The answer is 5a+15b-10
5 x a is 5a. 5 x 3b is 15b and 5 x -2 is -10.
You then put them together 5a+15b-10
I dont understand the question in english please xx
Answer:
A. -2 + 12 -2 ^ 3 + 2 ^ 0 * 3
= 10 - 2 ^ 3 + 2 ^ 0 * 3
= 10 - 8 + 1
= 3
B. 9 ^ (1/2)(25) - 8 + 2 + 3 ^ 2
= 9 ^ (1/2)(25) - 6 + 9
= 3 ^ 25 + 3
= 3 ^ 25 + 3
= 847288609446
C. 1/2 * 3/5 * (2 ^ 3 - 6) + 1/5
= 1/2 * 3/5 * 2 + 1/5
= 3/5 + 1/5
= 4/5
The area is 25π
Hope this helps
