Multiply then add
2x + 6
8x
Answer:
you have the answer correct actually
Step-by-step explanation:
Volume of a sphere with radius of 70 feet is:

where r is that radius
Because we need quarter sized tank of that radius we need to divide formula for volume by 4
Than we get:

V = 359188,76
Rounded:
V = 359189
Anyway, the value of 5 is 50 and the value of 6 is 6 as in the ones place.

she should have invested P, in order to get I = 6500
but she instead invested 17,801, how much more did she need? well, P - 17801
solve for P
