Step-by-step explanation:
sqrt(5x)×(sqrt(8x²) - 2×sqrt(x)) =
sqrt(5x × 8x²) - 2×sqrt(5x × x) =
sqrt(40x) × x - 2x × sqrt(5) =
2x×sqrt(10x) - 2x×sqrt(5)
therefore, the last option is correct.
1: square root of 2
2: cube root of 2, squared
3: square root of 3, squared
4: cube root of 3
hopefully this helps you :)
Answer:
11
Step-by-step explanation:
Plug in
0 for j to get 1
1 for j to get -2
2 for j to get 4
3 for j to get -8
4 for j to get 16
Then add 1 - 2 + 4 - 8 + 16 = 11
B but the last one in the b row
Answer:
-24
Step-by-step explanation:
4a+8-a
a=-2
4(-2)+8-(-2)
-8+-16
=-24
