for x = -1, y = 5 and let us assume that z = 1
It can be simply done by putting the values of x,y and z in the given expression.

We know that the value of 4² = 16
So,

So, the value of
is -16.
Find the scale factor: StartFraction enlarged over original EndFraction = StartFraction 6 over 3 EndFraction = 2
Calculate the perimeter of the original figure.
Multiply the perimeter of the original figure by the scale factor.
Step-by-step explanation:
A, C, D
A is incorrect - In decimal form, 7/5 is 1.4
B is incorrect - In decimal form, 7/4 is 1.75
D is incorrect - In decimal form, 7/2 is 3.5
The answer is C. 7/4; In decimal form, 7/4 is 2.33333333.... (this represents a terminating decimal)
