[tex] \sqrt{12} \times \sqrt{8} [/tex]
means
[tex] \sqrt{12 \times 8} [/tex]
then it will be
[tex] \sqrt{96} [/tex]
96 is not perfect square so
[tex] \sqrt{16 \times 6} [/tex]
and then
[tex] \sqrt{16} \times \sqrt{6} [/tex]
finally
[tex]4 \sqrt{6} [/tex]
is the answer
if it's helpful ❤❤❤

Which expression is NOT equivalent to 2m 3 +4?
A. 4 + 2m
B. 3m2+4
C. 2(m+2)
D. m+m2+3+1
Answer:
I believe the answer is B,
explanation:
Well, the others are exactly alike, the first answer is just the two numbers flipped, the third is where multiplication is needed, so (2 x m^3) + (2 x 2) = 2m^3 + 4. and the final one is m^3 plus itself which equals to 2m^3 + 4.

16 divided by (x + 4) in WORD FORM
Answer:
sixteen divded by the sum of x and 4
Step-by-step explanation:
Hey there!
In order to do 16 divided by (x+4), you can first do 16/x + 16/4. Then, simplify 16/4, and then the answer to the question is 16/x + 4.
Hope this is what you were looking for! Let me know if you need more help! Good luck and have a great day!

Answer:
25 degrees
Step-by-step explanation:
A right triangle is considered 90 degrees, so subtract 90 degrees by 65 degrees.
90 - 65 = 25
Hence, angle A equals 25 degrees.
Which line has a slope of 0.625, and which line has a slope of 1.6?
Explain why the slopes of these lines are 0.625 and 1.6.
Answer:
The answer is below
Step-by-step explanation:
The equation of a straight line is given by:
y = mx + b; where y and x are variables, b is the y intercept (i.e. value of y when x is zero), m is the slope of the line.
The slope of a line passing through the points [tex](x_1,y_1)\ and\ (x_2,y_2)\ is:[/tex]
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Let the point where the two lines intersect be the origin (0, 0).
Line 1 passes through (0, 0) and (8, 5). Hence:
slope of line 1 = [tex]\frac{y_2-y_1}{x_2-x_1}=\frac{5-0}{8-0} =0.625[/tex]
Line 2 passes through (0, 0) and (5, 8). Hence:
slope of line 2 = [tex]\frac{y_2-y_1}{x_2-x_1}=\frac{8-0}{5-0} =1.6[/tex]

The length of a rectangle is 1 inch less than twice its width, and its perimeter is 40 inches. Find the width of the rectangle.
7 in.
13 in.
14 in.
If the second equation is multiplied by 5 and then the equations are added, the result is _____.
x + 5y = 3
2x - y = -2
9x = 13
11x = -7
9x = -7
For the following system, use the second equation to make a substitution for x in the first equation.
x + 3y = 5
x + 7 = 2y
What is the resulting equation?
2y + 2x + 3y = 5
2y + 7 + 3y = 5
2y - 7 + 3y = 5

x 20
x ≥ 20
Answer:
1) 7 in
2) 11x=-7
3)2y - 7 + 3y = 5
4) i DONT'KNOWN
Step-by-step explanation:
1)
step 1
the length of the rectangle is 1 inch less than twice its width ( in other words , you have to subtract 1 to twice the width to get the length)
Let
L represents the length
W represent the width
Hence
Twice width= 2w
Now , replace
L=2w-1 equation (1)
Also
The perimeter =40 inches
[tex]perimeter= 2(L+W) 40=2(L+W) equation (2)[/tex]
Step 2
Solve for w
Replace equation (1) in equation (2)
[tex]40=2(L+W) equation (2)\\40=2((2W-1)+W)\\40=2(3W-1)\\40=6W-2\\Add 2 in both sides\\40+2=6W-2+2\\42=6W\\Divide both sides by 6\\\frac{42}{6}=\frac{6W}{6} \\7=W[/tex]
so ,the width is 7 in.
2) Given the equations
[tex]x+5y=3\\2x-y=-2[/tex]
The first step is to multiply the second equation by 5 (both sides of the equation)
[tex]5(2x-y=-2)\\5(2x-y)=5.(-2)\\5.2x-5.y=-10\\10x-5y=-10\\[/tex]
Next is to add both equations
x+5=3 +10x-5y=-10 = 11x+0y=-7
The result is 11x=-7
3)[tex]x+3y=5\\x+7=2y[/tex]
To make a substitution for x using the second equation in the first equation you :
1. solve for x the second equation
Subtract 7 in both sides of the equation:
[tex]x+7-7=2y-7\\x=2y-7\\[/tex]
2.Substitute the x in the first equation for the value of x you get in step 1 :
[tex]2y-7+3y=5[/tex]

What is the value of 100?
Answer:
10
Step-by-step explanation:
Means back the numbers into multiples of several small numbers
Like:; 1. We take LCM of 40
Just break into multiples of small number
40= 2×2×2×5
2. We take LCM of 50
50= 5×5×2
So LCM for 100 is 2×2×5×5
after that see the pairs in the LCM like 2×2 or 3×3 or 4×4(same numbers)
Then write the the single number in place of two multipled numbers
Like:; 2×2 is written as 2 // 3×3 is written as 3
So we can write 100 into 2×2×5×5 and then after selecting pairs (2×2)×(5×5)
write pairs in single number 2×5
And so we get 2×5=10
So we find root of 100 that is 10

Mr. gracia is at Dunkin' Donuts .he has $17.50 in his pocket ,and he buys a sandwich for $2.50 and 5 coffees using cash . Write an inequality to determine the possible cost of each coffee
Answer:
The coffee is $3 or less
Step-by-step explanation:
Set up an inequality where c is the cost of one coffee:
17.50 [tex]\geq[/tex] 5c + 2.50
Solve for c:
17.50 [tex]\geq[/tex] 5c + 2.50
15 [tex]\geq[/tex] 5c
3 [tex]\geq[/tex] c
So, the coffee is $3 or less

Kayla thinks that the slope of a vertical line is undefined, while Joshua argues that the slope of a vertical line is zero. Who is correct?
Answer:
Kayla
Step-by-step explanation:
Vertical lines are always undefined because if your answer has to be divided by zero, the answer is an undefined operation.
Horizontal lines always have the slope of zero!

The expression 8 + 2x can be written as _____.
4(2 + x)
2(4 + x)
2(4 + 2x)
Answer: 2(4 + x)
Step-by-step explanation:
i just multiplied across the parentheses. we can rule out the first option, because it would multiply out to be 8 + 4x.
the second option is the one that i calculated second, so i knew that i could rule out the last one my default.
just for kicks, if we multiplied the third option, it would come out to 8 + 4x.

Step-by-step explanation:
What are the coordinates of vertex B' if the figure is rotated
90° counterclockwise about the origin?
Answer:
Answer: B'(-5,2)
Step-by-step explanation:
Rotations
When rotating a point B(x,y) 90 degrees counterclockwise about the origin it maps to an image point B'(-y,x).
The image shows a figure formed by points ABCD. The coordinates of B are B(2,5).
This point will be rotated 90 degrees counterclockwise about the origin, thus the coordinates of the image point B' are B'(-5,2).
Answer: B'(-5,2)
