Answer:
20
Step-by-step explanation:
Assuming that the equation is x³ = 64, that can be solved by putting cube root on both sides like so: ∛(x³) = ∛64, which simplifies to <em>x = 4</em>.
Plugging that into our expression gives us <em>4² + 4</em>, which is 20.

Answer:
x=50
Step-by-step explanation:
1) Rewrite the problem as an equation: (x will be "a number")
9x+6=456
2) Subtract 6 from both sides:
9x=450
3) Divide both sides by 9:
x=50
Answer:
A
Step-by-step explanation:
for the number to be greater than 11 x cannot be negative so we can rule out C and D. 0 does not work as x so we can rule out B. we are left with A as the answer.
