Answer and Step-by-step explanation:
6 + 5![(8+2)^2\\](https://tex.z-dn.net/?f=%288%2B2%29%5E2%5C%5C)
<u>Add 8 and 2 together.</u>
6 + 5![(10)^2](https://tex.z-dn.net/?f=%2810%29%5E2)
<u>Now, square the number 10.</u>
6 + 5(100)
<u>Multiply 5 by 100.</u>
6 + 500
<u>Finally, add 6 to 500.</u>
506
<u>506 is the answer to the expression.</u>

The number is x
it is negative
the square is 28 more than 3 times itself
x²=28+3x
minus (28+3x)
x²-3x-28=0
factor
(x-7)(x+4)=0
set to zero
x-7=0
x=7
this is not the answer because we were told the number was negative
x+4=0
x=-4
correct
the number is -4
test
(-4)²=28+3(-4)
16=28-12
16=16
check
the number is -4
Answer:
x = 70
Step-by-step explanation:
Let me know if you need to show your work
The equation can be made by:
Letting x be the price of each tshirt sold
Y be the cost of washing cars
So the equation 1:
292.50 = 15x + 12y
Then the equation 2 is for this week:
<span>747.50 = 45x + 10y</span>
You won't want to move the decimal if you're finding 1%.
