It is B. 3(-3x)+2(2x-1)= -9x+4x-2—> (-5x-2)
Neither they are equal. 32 fluid ounces = 1 quart.

Answer:
88 problems
Step-by-step explanation:
98% of the total is 86 problems answered correctly.
(0.98)x = 86
x = (86/0.98)
x = 87.551
We need a whole number, so round to 88 problems
Answer:
The simplified equation is ![\pm\frac{\sqrt{b^2-4ac}}{2a}](https://tex.z-dn.net/?f=%5Cpm%5Cfrac%7B%5Csqrt%7Bb%5E2-4ac%7D%7D%7B2a%7D)
Step-by-step explanation:
Step 1:Applying Quotient Rule
![\sqrt[n]{\frac{a}{b}}=\frac{\sqrt[n]{a}}{\sqrt[n]{b}},\:\quad \mathrm{\:assuming\:}a\ge 0,\:b\ge 0](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5D%7B%5Cfrac%7Ba%7D%7Bb%7D%7D%3D%5Cfrac%7B%5Csqrt%5Bn%5D%7Ba%7D%7D%7B%5Csqrt%5Bn%5D%7Bb%7D%7D%2C%5C%3A%5Cquad%20%5Cmathrm%7B%5C%3Aassuming%5C%3A%7Da%5Cge%200%2C%5C%3Ab%5Cge%200)
=
----------------------------(1)
Step 2: Applying radical Rule
![\sqrt[n]{ab}=\sqrt[n]{a}\sqrt[n]{b},\:\quad \mathrm{\:assuming\:}a\ge 0,\:b\ge 0](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5D%7Bab%7D%3D%5Csqrt%5Bn%5D%7Ba%7D%5Csqrt%5Bn%5D%7Bb%7D%2C%5C%3A%5Cquad%20%5Cmathrm%7B%5C%3Aassuming%5C%3A%7Da%5Cge%200%2C%5C%3Ab%5Cge%200)
![\sqrt{4a^2}=\sqrt{4}\sqrt{a^2}](https://tex.z-dn.net/?f=%5Csqrt%7B4a%5E2%7D%3D%5Csqrt%7B4%7D%5Csqrt%7Ba%5E2%7D)
So equation(1) can be written as
-----------------------------(2)
Now
![\sqrt{4} = 2](https://tex.z-dn.net/?f=%5Csqrt%7B4%7D%20%3D%202)
![\sqrt{a^2} = a](https://tex.z-dn.net/?f=%5Csqrt%7Ba%5E2%7D%20%3D%20a)
Now equation(2) becomes
= ![\pm \frac{\sqrt{b^2-4ac}}{2a}](https://tex.z-dn.net/?f=%5Cpm%20%5Cfrac%7B%5Csqrt%7Bb%5E2-4ac%7D%7D%7B2a%7D)
