Answer:
1 or 2
Step-by-step explanation:
You need to make use of the distributive property, along with ...
![\sqrt{a}\cdot\sqrt{b}=\sqrt{ab}\\\sqrt{a}\cdot\sqrt{a}=a\qquad\text{meaning of square root}](https://tex.z-dn.net/?f=%5Csqrt%7Ba%7D%5Ccdot%5Csqrt%7Bb%7D%3D%5Csqrt%7Bab%7D%5C%5C%5Csqrt%7Ba%7D%5Ccdot%5Csqrt%7Ba%7D%3Da%5Cqquad%5Ctext%7Bmeaning%20of%20square%20root%7D)
Then
![\sqrt{7x}\left(\sqrt{x}-7\sqrt{7}\right)=\sqrt{7x}\cdot\sqrt{x}-7\sqrt{7x}\cdot\sqrt{7}\\\\=\sqrt{7}\sqrt{x}\sqrt{x}-7\sqrt{7^2x}=x\sqrt{7}-7\cdot 7\sqrt{x}\\\\=x\sqrt{7}-49\sqrt{x}](https://tex.z-dn.net/?f=%5Csqrt%7B7x%7D%5Cleft%28%5Csqrt%7Bx%7D-7%5Csqrt%7B7%7D%5Cright%29%3D%5Csqrt%7B7x%7D%5Ccdot%5Csqrt%7Bx%7D-7%5Csqrt%7B7x%7D%5Ccdot%5Csqrt%7B7%7D%5C%5C%5C%5C%3D%5Csqrt%7B7%7D%5Csqrt%7Bx%7D%5Csqrt%7Bx%7D-7%5Csqrt%7B7%5E2x%7D%3Dx%5Csqrt%7B7%7D-7%5Ccdot%207%5Csqrt%7Bx%7D%5C%5C%5C%5C%3Dx%5Csqrt%7B7%7D-49%5Csqrt%7Bx%7D)
Let's say that each pizza is sliced into 8 equal sized pieces, I have to make all of the fraction have the denominator of 8.
Conor: 1/4 * 2/2 = 2/8
Tyler: 3/4 * 2/2 = 6/8
Brandon: 2/8
Audrey: 4/8
Then I'll put the fractions in order from least to greatest. 2/8, 2/8, 4/8, 6/8. Then you would have to multiply each fraction by 2 since there are two pizzas that have 8 equally sized pieces.
Brandon: 2/8 *2/2 = 4/16
Conor: 2/8 * 2/2 = 4/16
Audrey: 4/8 * 2/2 = 8/16
Tyler: 6/8 * 2/2= 12/16
This means that Tyler ate the most of the two pizzas.

42
Step-by-step explanation:
168/4=42
Answer:
The correct answer options are,
A: 0
B: There is one real root with a multiplicity of 2.
Step-by-step explanation:
Discriminant of a quadratic equation ax² + bx + c = 0 is given by,
b² - 4ac
It is given a quadratic equation 9x² + 24x + 16 = 0
<u>To find the discriminant </u>
Here a = 9, b = 24 and c = 16
Discriminant = b² - 4ac
= 24² - (4 * 9 * 16)
= 576 - 576
= 0
The correct options are
A: 0
B: There is one real root with a multiplicity of 2.
