Answer:
B.
Step-by-step explanation:
Since the numbers in the root is all the same, lets say [tex]\sqrt{2}[/tex] is a variable.
7x[tex]\sqrt{2}[/tex] - 4[tex]\sqrt{2}[/tex] + x[tex]\sqrt{2}[/tex]
Group with like terms:
7x[tex]\sqrt{2}[/tex] + x[tex]\sqrt{2}[/tex] - 4[tex]\sqrt{2}[/tex]
Combine like terms:
8x[tex]\sqrt{2}[/tex] - 4[tex]\sqrt{2}[/tex]
There you have it! Since all the square roots are the same thing, we can treat them like variables.
the answer is B..................

What is the nth term rule of the quadratic sequence below?
8,14,22,32 ,44, 58, 74...
Answers
Answer:
y=n^2+3n+4
Step-by-step explanation:
Sequence,S: 8,14,22,32 ,44, 58, 74...
First differences of S: 6,8,10,12,14,16,...
Second differences of S: 2,2,2,2,2,2,....
It is indeed a quadratic since the 1st differences that are the same are the second differences.
So the 1st term is 8. If the 0th term was listes it would be 4 since 8-4=4 and 6-4=2.
This means our quadratic it is in the form
y=an^2+bn+c where c=4.
So we have y=an^2+bn+4.
Now we can find a and b using two points from our sequence to form a system of equations to solve.
(1,8) gives us 8=a(1)^2+b(1)+4
Simplifying gives 8=a+b+4
Subtracting 4 on both sides gives: 4=a+b
(2,14) gives us 14=a(2)^2+b(2)+4
Simplifying gives 14=4a+2b+4
Subtracting 4 on both sides gives 10=4a+2b
So we have the following system to solve:
4=a+b
10=4a+2b
I'm going to solve using elimination/linear combination style.
Dividing second equation by 2 gives the system as:
4=a+b
5=2a+b
Subtract the 2nd equation from the first gives:
-1=-1a
This implies a=1 since -1=-1(1) is true.
If a+b=4 and a=1, then b=3. Because 3+1=4.
So the equation is y=1n^2+3n+4 or y=n^2+3n+4.
please help me to solve this

Answer: x= 112°, y = 34°
Step-by-step explanation:
"Angles formed by drawing lines from the ends of the diameter of a circle to its circumference form a right angle."
That means the angle adjacent to 56° = 90° - 56° = 34°"The angle formed at the centre of the circle by lines originating from two points on the circle's circumference is double the angle formed on the circumference of the circle by lines originating from the same points."
The angle adjacent to the left of ∠X = 2(34°) = 68°x = 180° - 68° = 112°
The angle adjacent to the right of ∠X = the angle adjacent to the right of ∠X = 68°y = 68 ÷ 2 = 34°

Step-by-step explanation:
The area of a rectangle, given the coordinates of the vertices is found as follows;
1) The vertices of the rectangle ABCD are; A(-9, 8), B(-5, 5), C(1, 13), and D(-3, 16)
The length of side AB = √((-9 - (-5))² + (8 - 5)²) = 5
The length of side BC = √((1 - (-5))² + (13 - 5)²) = 10
The length of side CD = √((1 - (-3))² + (13 - 16)²) = 5
The length of side DA = √(((-9) - (-3))² + (8 - 16)²) = 10
The area of rectangle ABCD = 5 × 10 = 50 square units
2) The vertices of the rectangle EFGH are; E(30, 20), F(39, 29), G(49, 19), and H(40, 10)
The length of side EF= √((39 - 30)² + (29 - 20)²) = 9·√2
The length of side FG = √((39 - 49)² + (29 - 19)²) = 10·√2
The length of side GH = √((40 - 49)² + (10 - 19)²) = 9·√2
The length of side HE = √((40 - 30)² + (10 - 20)²) = 10·√2
The area of rectangle EFGH = 9·√2 × 10·√2 = 180 square units
3) The vertices of the rectangle IJKL are; I(-6, 2), J(2, 2), K(2, -8), and L(-6, -8)
The length of side IJ= √((-6 - 2)² + (2 - 2)²) = 8
The length of side JK= √((2 - 2)² + ((-8) - 2)²) = 10
The area of rectangle IJKL = IJ × JK
∴ The area of rectangle IJKL = 8 × 10 = 80 square units
4) The vertices of the rectangle MNOP are; M(5, 5), N(11, 5), O(11, -5), and P(5, -5)
The length of side MN = √((5 - 11)² + (5 - 5)²) = 6
The length of side NO = √((11 - 11)² + ((-5) - 5)²) = 10
The area of rectangle MNOP = 6 × 10 = 60 square units
5) The vertices of the rectangle QRST are; Q(10, 0), R(15, 5), S(25, -5), and T(20, -10)
The length of side QR = √((10 - 15)² + (0 - 5)²) = 5·√2
The length of side RS = √((25 - 15)² + ((-5) - 5)²) = 10·√2
The area of rectangle QRST = 5·√2 × 10·√2 = 100 square units
6) The vertices of the rectangle UVWX are; U(0, 5), V(15, 20), W(25, 10), and X(10, -5)
The length of side UV = √((0 - 15)² + (5 - 20)²) = 15·√2
The length of side VW = √((25 - 15)² + (10 - 20)²) = 10·√2
The area of rectangle UVWX = 15·√2 × 10·√2 = 300 square units

I need help right now before it due
Answers
Step 1: Write an equation
To start off, we will need to write an equation. We are told that this is an isosceles triangle, and are asked to use our knowledge of this shape to solve. An isosceles triangle has two angles that share the same degree. In this case, we can see that these are the bottom two angles, one of which is labeled as x. This means that the equation will be 98, in addition to 2x, equaling 180. This is because in a triangle, each angle will come together to equal 180. Let’s formally write the equation now.
98+ 2x= 180
Step 2: Solve
All we have left is solving the equation. Let’s rewrite the equation to start.
98+ 2x= 180
Now let’s work to isolate x. To start, we need to move the constant to the right side. Let’s subtract 98 from each side.
98+ 2x= 180
2x= 82
Great! In the final step, we can find the value of x. To do so, we need to divide each term by 2. This will give us our answer.
2x= 82
x= 41
X is equal to 41°. Hope this helps! Comment below for more questions.

a box of candy contains 0.6 of pounds of caramels and 3.6 pounds of coconut what precent of the contents of the box
Answers
Answer:
We know that the box has:
0.6lb of caramels
3.6lb of coconut.
Then the total mass of candy in the box is:
0.6lb + 3.6lb = 4.2lb
This is the 100% of the box.
Now, we can write this as:
4.2lb = 100%
For example, if we want to know which percentage is caramels, we write the equation:
0.6lb = X
We want to find the value of X
Then we have two equations:
0.6lb = X
4.2lb = 100%
Let's take the quotient of these two equations:
(0.6lb/4.2lb) = X/100%
Now we can solve this for X:
(0.6lb/4.2lb)*100% = X = 14.3%
the caramels represent the 14.3% of the wheight of the box.
And for the coconut candy, we have the relation:
3.6lb = Y
Now let's do the same again, we start with the two equations:
3.6lb = Y
4.2lb = 100%
Take the quotient:
(3.6lb/4.2lb) = Y/100%
Solve for Y:
(3.6lb/4.2lb)*100% = Y = 85.7%
Now we found the percentage that represent each type of candy in the box.

a_(n)=7n-1 9 ( what is the fourth term)
PLEASE HELP ASAP.
Answers
Answer:
Fourth term of given arithmetic progression a(4) = 30
Step-by-step explanation:
Given incomplete information:
a(n) = 7n - 1 9
Assume Correct information:
a(n) = 7(n - 1) + 9
Find:
Fourth term of given arithmetic progression
Computation:
Fourth term of given arithmetic progression = a(4)
So,
Number of term (n) = 4
So,
a(n) = 7(n - 1) + 9
a(4) = 7(4 - 1) + 9
a(4) = 7(3) + 9
a(4) = 21 + 9
a(4) = 30
Fourth term of given arithmetic progression a(4) = 30
A sector of a circle of radius is 15Cm, and angle 216 degrees is bent to form a cone. What is base radius of the cone and the vertical height of the cone?
Answers
Answer:
Step-by-step explanation:
Radius r = 15
Circumference = 2πr = 30π cm
Circumference of cone = arc length of sector
= 30π × 216°/360°
= 18π cm
Radius of base of cone = 18π/(2π) = 9 cm
Slant height of cone = radius of circle = 15 cm
Height of cone = √(15² - 9²) = 12 cm

Find the equation of the line that
is perpendicular to y = -4x + 3
and contains the point (8, 1).
Answers
Answer:
x-4y=8
Step-by-step explanation:
y=mx+c comparing with given eq
we get slope(m1)=-4
since both are prependicular
m1×m2=-1
-4×m2=-1
m2=1÷4
eq:-y-y1=m2 (x-x1)
y-1=(1÷4)(x-8)
x-4y=4
perpendicular means the y-intercept stays the same (so 3 stays), but the slope would be the opposite reciprocal of the original.
the opposite of -4 is 4. opposite of negative=positive.
the reciprocal of 4 is 1/4
so the new slope is 1/4
since we have a point, you plus everything on the point slope-form.
y-y1=m(x-x1)
(8,1)—> the 8 is x1 and the 1 is y1
the slope is m
so it’ll be
y-1=1/4(x-8)
solve. first distribute the 1/4
y -1=1/4x - 2
add 1 to both sides
y= 1/4x - 1
