What is -2(x+5)=4 ????

faust18 [17]

Multiply -2 and x, and you’ll have -2x. Then multiply -2 and 5, and you’ll have -10. Therefore, -2x-10=4, but we’re not done yet. We need to get x by itself, so what we’re gonna have to do is add 10 to both sides. Now you’ll have -2x=14, and when you divide both sides by -2, you’ll have x=-7 which will be your answer

Evaluate (-3) to the power of 4

Alexxx [7]

Answer:

-81

Step-by-step explanation:

Write it out, so it's more clear: $-3^{4}$
Because the base number of the equation (-3) is a negative, we know the answer will be a negative
Multiply -3 by itself 4 times: -3 × 3 × 3 × 3
-3 × 3 × 3 × 3 = -81
