You would first substitute -7 for m and 2 for n. It would look like this: 4| -7-2 | . we first solve the absolute value because it is the first step in PEMDAS or order of operations. -7-2 is equal to -9. Our equation should look like this now: 4 |-9| . we solve the absolute value portion, the absolute value of a negative number is the the same number but positive. the absolute value would be 9. (we just take the negative symbol off). we now have 4 x 9. This is equal to 36.
36 is the answer.
Answer: they had a bad reputation
Step-by-step explanation:
By determining the area of the square, we get 
Step-by-step explanation:
Step 1:
The area of a square is given by squaring its side length.
The given squares side length is
cm.
The area of a square
Here a is the side length.
The area of the square is given as 7 cm².
Step 2:
Substituting the value of a in the equation, we get

Taking the x values on one side and the constants on the other side, we get

So 
So it has been proved.
Image of the triangle is attached
Answer:
24 cm
Step-by-step explanation:
If two triangles are similar, the corresponding sides must be in the same ratio.
From the diagram, the height of the triangle is 36cm.
But the height of triangle ABE = h,
To find the height of triangle BCD, let's subtract the height of triangle ABE from 36cm.
Therefore.
Height of BCD = 36 - h.
Since the triangles are similar and their corresponding sides have the same ratio, we have the expression:
Substituting figures, we have:
Cross multiplying, we have:
20(36-h) = 10 * h
720 - 20h = 10h
720 = 10h + 20h
720 = 30h

h = 24 cm
Therefore, the height of triangle ABE is 24cm
2/2 which = 1 whole is the slope
