If 3x + 8 = -4, then
evaluate x3 + 5

-59

Step-by-step explanation:

x3 is meaningless; I assume you meant x^3.  

If that's the case, then:

3x + 8 = -4 is equivalent to 3x = -12, so that x = -4.

Then (-4)^3 + 5 = -64 + 5 = -59

-59

Step-by-step explanation:

the question can be solved by some simple mathematical steps.

If 3x + 8 = -4

then, x3 + 5 =?

from 3x + 8 = -4

collect the like terms

3x = -4 - 8

3x = -12

divide both sides by 3

3x/3 = -12/3

x = -4

if x = -4 then to find  x3 + 5 will imply that we will insert the value of x = -4 into the x3 + 5

-4 ³ + 5

-64 + 5

= -59

therefore the value of x3 + 5 is solved to be -59

the answer is a

step-by-step explanation:

because if you put 1 in to the square root of x it equals 300.
