Solve x2 – 64 = 0.
1. Isolate x2: x2 = 64
2. Apply the square root property of equality: Vx2 = 1/64
3. Isolate the variable:
X=_
X=_

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2

the answers might not be correct use at own risk

y=-2.5x+12.5

step-by-step explanation:

5y=2x+10

y=0.4x+2

slope=-2.5

5=-2.5*3+b

b=12.5

d. corresponding side lengths in similar triangles are proportional in length.
