X^2
You subtract exponents when dividing exponents
Answer:
Because 3(5x) is the same as 3 *5 * x
Step-by-step explanation:
When a number is next to another in parantheses, it signifies multiplication. In this case, we already have 5 and x grouped together by a multiplication sign, so the entire thing is 5 * x. The statement below is key
Distribution in multiplication is only possible if a variable is grouped to another real number by a plus or minus sign.
So in this case, we have 3 * 5 * x, which is 15x. However, if we had 3(5 + x), we would have 15 (3 * 5) + 3x (3 * x).
Hopefully that makes sense!
<h3><u>Eight can only go into 20 </u><u>
two </u><u>full times.</u></h3>
8 * 2 = 16
16 + 8 = 24 ≠ 20
Answer:
11.5
Step-by-step explanation:
Simple interest formula:
where
I = interest
P = principal
r = rate
t = time
In your case,
P = $4,000
I = $4,920 - $4,000 = $920
t = 2 years
So,
The rate as decimal is 0.115 that is 11.5% as percent
