Answer:
10x²+11-2x
Step-by-step explanation:
I hope you mean 7x²+8+5, not 7x²+8x+5.
We need to combine like terms. Anything with squared should be added together, et cetera.
(7x²+8+5)+(3x²-2x-2)
You can take out the parenthesis, because they don't matter in addition.
7x²+8+5+3x²-2x-2
Add the terms, step by step. Each bold pair needs to be added together.
7x²+8+5+3x²-2x-2
10x²+8+5-2x-2
10x²+11-2x
Now there's no more we can add together.
Answer:
You add the parts then subtract them with the old part

Answer:
Leslie should buy her dog food from Petsmart because the price per can is cheaper
Step-by-step explanation:
Step one;
given data
At Petco, we are told that she receives 9 packs with four cans each for $25
Hence Petco gives a total of 9*4= 36cans
the cost of each can will be 25/36
=$0.69 per can
Step two:
At Petsmart, we are told that she receives 7 packs with six cans each for $25
Hence Petsmart gives a total of 7*6= 42cans
the cost of each can will be 25/42
=$0.59 per can
<u>Leslie should buy her dog food from Petsmart because the price per can is cheaper </u>
Answer:
1. $327.60
2. $21,560.00
3. $2,208.28
Step-by-step explanation:
The formula for simple interest is:
I = Prt
where
I = amount of interest
P = principal amount
r = annual interest rate
t = number of years
The total future amount after earning simple interest is the principal polus the interest.
F = P + Prt
F = P(1 + rt)
1.
F = P(1 + rt)
F = $210(1 + 0.08 * 7)
F = $327.60
2.
F = P(1 + rt)
F = $14,000(1 + 0.06 * 9)
F = $21,560.00
3.
F = P(1 + rt)
F = $1,900(1 + 0.059 * 2.75)
F = $2,208.28
