Answer:
3 units.
Step-by-step explanation:
We can calculate the length, since it only moves on the "x" axis, since on the "y" axis, it remains the same.
We know that between -2 to 5, there are 7 units. 2 + 5 = 7.
Therefore this would be the length.
We know that the perimeter is equal to:
p = 2 * w + 2 * l
P = 20
20 = 2 * w + 2 * 7
2 * w = 20 - 14
w = 6/2
w = 3
therefore, the width value is 3 units.
Answer:
Step-by-step explanation:
(a²-2ab+b²)=(a-b)²
a²+2ab+b²=(a+b)²
i solve b and d
(b)
9x²-36x+36=0
(3x)²+2×3x×-6+(-6)²=(3x-6)²
(d)
a²-b²=(a+b)(a-b)
4x²-81=0
4x²-81=(2x)²-9²=(2x+9)(2x-9)
