1. Its C
2. The answer is A
For the answer to the question above, It m<span>eans Brian is switching from saving $25 dollars a week to $35 dollars a week. Because every week Brian will add $25 to his savings account (In week 1, Brian adds $25. In week 2 Brian adds $50. And so on). So to change from 25 to 35 would mean that Brian is saving more money every week ($10 to be exact). </span>
<span>And if you're curious, $350 stands for the amount of money Brian has initially (because at 0 weeks, Brian has $350 in his savings account).
I hope this helps</span>
C = 6/(6+ 12)*180 We solve the bracket first.
C = 6/(18)*180 From here we can solve any first.
= 1/3 * 180
= 60
You could rewrite this as double brackets, as you are multiplying together two sets of two terms. It would then look like:
(8i + 6j)(4i + 5j)
and you can expand by multiplying together all of the terms
8i × 4i = 32i²
8i × 5j = 40ij
6j × 4i = 24ij
6j × 5j = 30j²
To get your final answer, you then just need to add together all of the like terms, and get 32i² + 30j² + 64ij
I hope this helps!
Answer:
The answer is C
Step-by-step explanation:
This is the answer because you substitute x-3 for y in the second equation. So yes, C is the answer.
