Answer:
We have the expression -1(2x + 3) - 2(x - 1).
Distribute the -1 across the 2x and 3.
-1(2x + 3) - 2(x - 1) = -2x - 3 - 2(x - 1)
Now distribute the 2 across the x and -1.
-2x - 3 - 2(x - 1) = -2x - 3 - 2x + 2
Combine like terms.
-2x - 3 - 2x + 2 = -4x - 1
So, D -4x - 1 is the answer.
Answer:
160
Step-by-step explanation:
add the numbers together then divide by 8
The answer to this is false.
Answer:
B.
Step-by-step explanation:
The original equation is cos 64 = 32/k. To solve for k we need to isolate it. we can multiply by k then divide by cos 64. This gives us the equation k = 32/cos 64. Therefore, B is the right answer.
<h3>I'll teach you how to solve (81x^-20 y^-16)^-3/4</h3>
---------------------------------------------------------------
(81x^-20 y^-16)^-3/4
Apply exponents rule:
(81x^-20 y^-16)^-3/4=
1 / (81x^-20 y^-16)^-3/4
Simplify (81x^-20 y^-16)^-3/4:
1/27/x^15 y^12
Apply the fraction rule:
x^15 y^12 / 27
Your Answer Is x^15 y^12 / 27
