Does anyone know how to do

rearrange to make z the subject of the formula

r=4-2(5-3z)^2

I believe the answer is:

r-4=-2(5-3z)^2

r-4/2= (5-3)^2

√r-4/2= 5-3z

-5+√r-4/2=3z

divide all by 3

step-by-step explanation:

i think you should think about the question and not look online.

your answer is 228

step-by-step explanation:

add the top and bottom bases together, then divide them by 2, then multiply by the height.
