Which equations are correct? all that apply -2b^3(6b^2+5)= - 12b^5-10b^3

- 7x^2(4x^3+2)= - 28x^6-14x^2

- 3y^4(5y^2+2)= - 15y^8- 6y^4

- 5d^3(3d^2+4)= - 15d^5-20d^3

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
