What is the solution set of 2x2 + x = 15?

Step-by-step explanation:

X=11

Step-by-step explanation:

2x 2 + x = 15

2x 2 + x -15 = 0

(2x - 5)(x+3) = 0

2x-5=0

x = 5/2

x+3=0

x=-3

answer {-3, 5/2}

step-by-step :

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
