Evaluate the expression (2x + 5)2 – 3x at the value r=-1. Evaluate the expression
(36-1)' + 5t at the value = 0.

Evaluate the expression (31 - 1)* + 5+ at the value 1 = 2.

Evaluate the expression (31 - 1)' + 5t' at the value = -1.

i think c. but don't trust it.

step-by-step explanation:

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

ask the math teacher she or he would know lol.

step-by-step explanation:

secant-secant formula:

(whole secant) x (external part) =           (whole secant) x (external part)

(8+y-2) *8=                                           (y+4+6) *6

(y+6)*8 = (y+10) *6

distribute

8y+48 = 6y +60

subtract 6y from each side

2y +48 = 60

subtract 48 from each side

2y = 12

divide by 2

y = 6

sv =     (y+4+6)

sv   = 6+4+6

sv = 16
