1/4d=1/5g(g+e)-h <br> solve for d<br> Please show your work.
loris [4]

Answer:

See below

Step-by-step explanation:

To solve for d, multiply both sides of the equal sign by 4.

4(1/4d) = 4 (1/5g(g+e)-h)

4/4d = 4(1/5g^{2} + 1/5ge - h)

d = 4/5g^{2} + 4/5ge - 4h

kirza4 [7]
Answer is a1 = 7

Using equation (derived from formula to find sum of values in a geometric series),
77 \:  =  \frac{a(1 - (  { - 2}^{5}))}{1 - ( - 2)}
Hence, solve for a.
