Answer:
15 a^2 + -10 a b
Step-by-step explanation:
Expand the following:
5 a (-2 b + 3 a)
Hint: | Distribute 5 a over -2 b + 3 a.
5 a (-2 b + 3 a) = 5 a (-2 b) + 5 a (3 a):
-2 5 a b + 5 3 a a
Hint: | Combine products of like terms.
5 a×3 a = 5 a^2×3:
5×3 a^2 - 2×5 a b
Hint: | Multiply 5 and 3 together.
5×3 = 15:
15 a^2 - 2×5 a b
Hint: | Multiply 5 and -2 together.
5 (-2) = -10:
Answer: 15 a^2 + -10 a b
Answer:
9
Step-by-step explanation:
Create a ratio
3:8
Since the total(denominator) is 8.
We can find a ratio of 24 total students so,3:8.
3:8
_:24
You multiply 3 on each side.
8×3=24
3×3=9
C I think because all of them add up to it so it would be 5seconds
You have $284 in your credit card balance. 186-174= 12. 99+35= 134 and then 12-134= -122. So 406-122= 284.
Answer:
Equation: S = 650 + 40w
Ryan has $1290 in his savings after 16 weeks.
Savings = S
weeks = 16
S = 650 + 40w
S = 650 + 40(16)
S = 650 + 640
S = 1290
