Answer:
Step-by-step explanation:
<u>Simplify</u>
- 6√20 + 8√5 - 5√45 =
- 6√4(5) + 8√5 - 5√9(5) =
- 6(2)√5 + 8√5 - 5(3)√5 =
- (12 + 8 - 15)√5 =
- 5√5
(-3/8)x+y=(-4), standard form formula is ax +by = c. So you just move them to the correct sides by adding or subtracting.
Step-by-step explanation:
for part A
7x-6x+4x
x+4x
=5x
for part B
3(3-9y)
9-27y

<u>Answer:</u>
- Colin will have $2365 after 3 years.
<u>Step-by-step explanation:</u>
<u>Using PRT/100, we can find the interest and then sum it up with the principle amount.</u>
- => 2200 x 2.5 x 3/100 = Interest
- => 22 x 2.5 x 3 = Interest
- => 55 x 3 = Interest
- => 165 = Interest
- => 2200 + 165 = Total amount
- => $2365
Hence, <u>Colin will have $2365 after 3 years.</u>
Hoped this helped.
