Answer:
I think it´s B
Step-by-step explanation:
A. 19 B. 17 C. -11 D. 21
The given expression is 5a+5b The given values of a and b are a=-6 ,b=-5
Substituting the values of a and b in the expression we have :
5a+5b= 5(-6)+5(-5)
= -30 -25 ( when a positive and a negative number is multiplied the result is a negative number)
-30-25=-55 (same signs are added)
The answer to the expression 5a+5b when a=-6 anf b=5 is -55.
[The given options are not correct.]
B. $55 + w = $605
C. $605 – $55 = w
D. $55 – w = $605 – w
Answer:
A
Step-by-step explanation:
Explain when is a rational expression restricted.
2^a X 2^b X 2^c
2^a+b X 2^a-b
