Answer:
76w + 17
Step-by-step explanation:
7 ( 5 + 4w ) + 6 ( 8w - 3 )
= 7 ( 5 ) + 7 ( 4w ) + 6 ( 8w ) - 6 ( 3 )
= 35 + 28w + 48w - 18
= 28w + 48w + 35 - 18
= 76w + 17
Answer:
B
Step-by-step explanation:
<em>Let's multiply this out and combine like terms:</em>

So there are 2 terms.
Answer choice B is right.
Answer: B= A/(C+D)
Step-by-step explanation:
A = B(C+D)
Divide each side by B
A/B= C+D
Reciprocate both sides
B/A = 1/(C+D)
Now multiply each side by A
B = A/(C+D)
Answer: C all real numbers
