Marina86 [1]

Answer:

The equivalent to -(-5.25) = 5.25

Step-by-step explanation:

Given

$-(-5.25)$

We need to determine the equivalent to -(-5.25)

some of the sign rules are:

+(+) = +

−(−) = +

+(−) = -

−(+) = -

Thus,

$-(-5.25)$

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