Answer:

We need 8 cement spheres. With each on sphere being made, we use 2.5ft of cement.

To figure out this problem, all we need to do is 8 x 2.5

8 x 2.5ft = 20ft

~Hope this helps~

Use the identity below to complete the tasks: a3 − b3 = (a − b)(a2 + ab + b2) When using the identity for the sum of two cubes t

saveliy_v [14]

Answer:

a= $5q^ {2}$

b= $r^{2}s$

Step-by-step explanation:

Here $125q^{6}$ is like the $a^{3}$ in the general formula.

So we can write $125q^{6}$ as:

$(5q^ {2} )^{3}$

We can also write $r^{6} s^{3}$ as:

$(r^{2}s)^{2}$

Therefore:

a³= $(5q^ {2} )^{3}$

b²= $(r^{2}s)^{2}$
