Answer:
See below.
Step-by-step explanation:
Just like 18, continue with 19-21. Solve for x by rewriting each equation in log form.

When rewriting the form, the base of the exponent becomes the base of the log.
h = 6
l = 8
w = 6
surface area = 2 (wl +hl +hw) =
2( (6*8) +(6*8)+(6*6)) =
2(48 +48 +36)=
2(132)= 264 square inches
Answer:
-10/3 is the answer
Step-by-step explanation:
Given are two complex numbers as

Recall Demoivre theorem as
(cosA+isinA)(cos A+isin B) = cos(A+B)+isin(A+B)
Hence here we have sum of angles as
A+B = 63+117 =180

=
Since sin180=0 and cos 180=-1
The way we simplify this is by using the distributive property and multiply every term by 0.5. When we do this we get 2a+3b
Answer:
That would be A) -3/5.
