Answer:
Option 2 which is r^6
Step-by-step explanation:
You need to apply the exponent rules.
Since the r's are the same, you can subtract the exponents.
r^9 - r^3 = r^6
Notice that the bases ("r") stayed the same.
Answer:
John is 31
Ella is 25
Step-by-step explanation:
Let sister's age be x, then John's age is (x + 6). So from sentence 2,
(3x) - 2(x + 6) = 13
3x - 2x - 12 = 13
x = 13 + 12 = 25
and x + 6 = 31
Answer:
I think it would be 4x
Step-by-step explanation:
Heres how. At first you ignore the exponent (you'll come back to it) 12x ÷ 6x = 2x. Then you have to solve with the exponent. 2 × 2 = 4 then add the label. 4x, and that's how you get the answer. Hope this helps.
