Answer:
2
Step-by-step explanation:
The answer is 2 because the expression tells you that the numbers in parentheses are the ones you start with first. In this case you need to start from left to right since both sides are in symbols.
1. 3x4=12
2. 24-18=6
3. 12/6=2

What are the zeros of the polynomial function F(x) = x3 - 5x2 - 6x?
Answer:
The zeros are {2, 3}
Step-by-step explanation:
Please use " ^ " to indicate exponentiation:
F(x) = x^3 - 5x^2 - 6x
Factoring out x, we get:
F(x) = x(x^2 - 5x - 6)
Factoing the quadratic, we get:
F(x) = x(x - 3)(x - 2) = 0
The zeros are {2, 3}

Select all that are measures of angles that are coterminal with a -50° angle.
-770°
-530°
-410°
50°
310°
360°
410°
670°
Answer: -770, -410, 310, 670 degrees
Step-by-step explanation:
Coterminal angles are angles that are have the same sides ... they are essentially the same angle, but are, for example, rotated an extra 360 degrees.
You can add/subtract 360 degrees to check if angles are coterminal:
-770 = -50 - 360 - 360 -- YES, it is coterminal with a -50 degree angle.
-530 [tex]\neq[/tex] -50 - 360 ... -- NO
-410 = -50 - 360 -- YES
50 [tex]\neq[/tex] -50 + 360 ... -- NO
310 = -50 + 360 -- YES
360 [tex]\neq[/tex] -50 + 360 ... -- NO
410 [tex]\neq[/tex] -50 + 360 ... -- NO
670 = -50 + 360 + 360 -- YES

Use the right triangle ABC. The figure is for reference only and is not drawn to scale. If AC = 16 cm and AB = 34 cm what is the length BC?
Answer:
AB = 34 and AC = 16
BC^2 = 34^2 - 16^2
BC^2 = 1,156 - 256
BC^2 = 900
BC = 30
Step-by-step explanation:
What is the value of X in the figure?
Answer:
x = 360/7
Step-by-step explanation:
the sum of 3x and 2/4x is supposed to be 180 degrees.
1.- write it as an equation.
3x + 1/2x = 180
2.- Combine like terms.
3x + 1/2x = 7/2x
7/2x = 180
3.- divide.
180 / 7/2 = 360/7
What type of triangle, if any, can be formed with angle measures of 32, 126, and 32
-only an acute isosceles triangle
-either an acute isosceles triangle or an obtuse isosceles triangle
-no triangle
-only an obtuse isosceles triangle
Answer:
No triangle
Step-by-step explanation:
All triangles must have angles that measure up to 180 degrees. When you add 32, 32, and 126 you get 190. That means that no triangle can be formed.

Explain, with a test, why the two triangles in each figure are similar. Find the
unknown lengths.
Answer:
x = 3, y = 6
Step-by-step explanation:
In the figure attached,
If ΔADE and ΔABC are similar triangles, their corresponding sides will be in the same ratio.
By this property,
[tex]\frac{AB}{AD}=\frac{AC}{AE}=\frac{BC}{DE}[/tex]
[tex]\frac{AB}{AD}=\frac{AC}{AE}[/tex]
[tex]\frac{AD+BD}{AD}=\frac{AE+EC}{AE}[/tex]
[tex]\frac{3}{2}=\frac{x+1.5}{x}[/tex]
3x = 2x + 3
3x - 2x = 3
x = 3
Similarly, [tex]\frac{AB}{AD}=\frac{BC}{DE}[/tex]
[tex]\frac{3}{2}=\frac{y}{4}[/tex]
y = [tex]\frac{3\times 4}{2}[/tex]
y = 6

Answer:
B, C and E
Step-by-step explanation:
To get the expressions that have the same solution as the given expression;
first, we need to get the result of the given expression.
-4(6) = -4 * 6
-4(6) = -24
the next step is to test each of the given options.
A.
-4(-6) = -4 * -6
-4(-6) = 24
B.
4(-6) = 4 * -6
4(-6) = -24
C.
6(-4) = 6 * -4
6(-4) = -24

Answer: (5, 12, 13).
Step-by-step explanation:
Pythagorean triples are any three side lengths of a right triangle that are all whole numbers.
The most common triples are (3, 4, 5), (5, 12, 13), and (9, 40, 41).
You can test the options given in the Pythagorean theorem to see if they make the theorem correct.
25 + 64 = 100 is not correct.
9 + 16 = 36 is not correct.
25 + 144 = 169 is correct.
1 + 1 = 4 is not correct.
The correct choice is (5, 12, 13).

2. The lengths of two insects are given below.
Ladybug: 10 millimeters
Walking stick: 30 centimeters
What is the difference in length of these two insects in millimeters
A 70 mm
B 20 mm
C 290 mm
D 2,990 mm
The conversion rate of millimetres to centimetres is 10 = 1 (Meaning 10 millimetres will equal one centimetre).
Knowing this, we can convert the centimetres to millimetres by multiplying by 10.
30 x 10 = 300
So a walking stick is 300 millimetres long.
To find the difference, we need to subtract the larger number from the smaller one.
300 - 10 = 290
Therefore the answer is 290mm.
Hope this helps! :)
what is the missing constant term in the perfect sqaure that starts with x^2 - 4x
Answer:
The expression is; x^2 – 4c + 4
Step-by-step explanation:
For the expression to be a perfect square, let us say the constant term should be assigned as ⇒ c;
This creates of following expression;
x^2 - 4x + c
In order to be a perfect square, the discriminant needs to be zero ;
( - 4 )^2 - 4 * ( 1 )c = 0 ,
16 – 4c = 0 ,
4c = 16 ,
c = 4 ,
Solution; The expression is, therefore; x^2 – 4c + 4

plz help me. its " joseph runs 2/3 of a mile in 8 minutes. if joseph runs at that speed, how long will it take him to run 1 mile. and show your work". PLZ HELP ME ILL GIVE U 20 POINTS.
Answer:
He runs 2/3 mile in 8 mins, he runs one mile in 12 mins
It will take Joseph 12minutes to run 1 mile
Speed is defined as the ratio of the distance covered to the time taken.
If Joseph runs 2/3 of a mile in 8 minutes, then;
[tex]\frac{2}{3} miles = 8minutes[/tex]
In order to calculate the time it will take Joseph to run 1 mile, we can write:
[tex]1mile=x[/tex]
Divide both expressions
[tex]\dfrac{\frac{2}{3} }{1} =\dfrac{8}{x} \\\dfrac{2}{3}=\dfrac{8}{x}[/tex]
Cross multiply
[tex]2x=3 \times 8\\2x=24\\x=\frac{24}{2} \\x=12minutes[/tex]
This shows that it will take Joseph 12minutes to run 1 mile.
