What she did:
![\sqrt{-2x + 1 } - 1 = x + 3 - 1 \sqrt{-2x} = x + 2](https://tex.z-dn.net/?f=%20%5Csqrt%7B-2x%20%2B%201%20%7D%20-%201%20%3D%20x%20%2B%203%20-%201%20%5Csqrt%7B-2x%7D%20%3D%20x%20%2B%0A2)
What she should have done:
![( \sqrt{-2x + 1} ^{2} = (x + 3)^2 -2x + 1 = (x + 3)^2 -2x + 1 - 1 = (x + 3)^2 - 1 -2x = (x +3)^2 - 1](https://tex.z-dn.net/?f=%28%20%5Csqrt%7B-2x%20%2B%201%7D%20%5E%7B2%7D%20%3D%20%28x%20%2B%203%29%5E2%20-2x%20%2B%201%20%3D%20%28x%20%2B%203%29%5E2%0A-2x%20%2B%201%20-%201%20%3D%20%28x%20%2B%203%29%5E2%20-%201%20-2x%20%3D%20%28x%20%2B3%29%5E2%20-%201)
The error that Eloise made in solving the radical equation
was that she subtracted 1 before squaring both sides.
<span>To add, the equation where at least one variable expression
is fixed inside a radical, usually a square root is called a radical equation.</span>
Answer:
10x⁶-6x³+10x²-6 answer
Step-by-step explanation:
(7x6 + 10x2 − 10) + (3x6 − 6x3 + 4)
7x⁶ + 10x² -10 + 3x⁶ -6x³ +4
add all coffitient
10x⁶-6x³+10x²-6 answer

The resulting equation after the first step in the solution would be 4p - 7 = 13
I got 1.78 but I'm not really sure but hope it helps
Nina makes 11.25 per hour.
Step-by-step explanation:
Given,
Number of hours worked by Nina = 32 hours
Amount earned by Nina = 360
Let,
x represent the amount earned by Nina per hour.
Amount per hour * Number of hours = Amount earned
![32*x=360\\32x=360](https://tex.z-dn.net/?f=32%2Ax%3D360%5C%5C32x%3D360)
Dividing both sides by 32
![\frac{32x}{32}=\frac{360}{32}\\x=11.25](https://tex.z-dn.net/?f=%5Cfrac%7B32x%7D%7B32%7D%3D%5Cfrac%7B360%7D%7B32%7D%5C%5Cx%3D11.25)
Nina makes 11.25 per hour.
