How does the formula S=2B+Ph apply to finding the surface area of a right prism?

no, the equation would be invalid since they are both not equal.

step-by-step explanation:

here you got

4y-6+4y 2-9

first, you would simplify the equation on the form.

4y-6+4y 2-9

then, move all the terms that contains a y to the left and all the other terms to the right.

+4y-4y+-9-6

finally, you will simplify the left and the right side of the equation.

y=-3

it is contrapositive

i could not see the question too well so check yourself again too . this is because i want you to get it correct.

b, i believe, but not sure.
