Question

ADD.....7/25z^3 + 1/35z^2 ADD.....7/25z^3 + 1/35z^2 @Mathematics

Answer 1

the powers of the zs are not the same so they cannot be added unless you have a value for z

Answer 2

i dont underdstand what that means. I know i have to factor out each denominator

Answer 3

i have that part so far

Answer 4

(7/25)z3 +(1/35)z2 =(1/5)z2((7/5)z +(1/7))

Answer 5

that can't be simplified. if you have x^2 and x^1, you can't add them because the powers aren't the same. that is as far as you can go unless the tell you what z equals.

Answer 6

answer is (49+5Z)/(175Z^3

Answer 7

ugh i see what i did wrong!

Answer 8

(1/5)z2((49z +5)/35)
