Answer:

A. The solution set is x = 5 or -7

Step-by-step explanation:

$\sqrt[4]{ {x}^{2} + 2x } = \sqrt[4]{35} \\ {({x}^{2} + 2x) }^{ \frac{1}{4} } = {(35)}^{ \frac{1}{4} } \\ {x}^{ \frac{1}{2} } + {2x}^{ \frac{1}{4} } = {35}^{ \frac{1}{4} } \\ {x}^{2} + 2x = 35 \\ {x}^{2} + 2x - 35 = 0 \\ (x - 5)(x + 7) = 0 \\ x = 5 \: or \: - 7$

Therefore, the answer is A. as the solution is x = 5 or -7

Simplify into one fraction<br><br> 8x-2/x-8-2/x-8

Elis [28]

$\frac{8x-2}{x-8} - \frac{2}{x-8}$

The fractions already have a common denominator of x-8, so all wee need to do is combine the numerators:

$\frac{8x-2-2}{x-8}$

$\frac{8x-4}{x-8}$

Express the fractions 3/4, 7/16, and 5/8 with the LCD. A. 9/16, 49/16, 36/16 B. 12/16, 7/16, 10/16 C. 24/32, 14/32, 24/32 D. 3/4

True [87]

Answer:

Step-by-step explanation:

the denominator you want is 16 so 4(4) is 16, which makes 3(4) 12 so 12/16. 7/16 is already perfect. 8(2) is 16 therefore 5(2) is 10 which makes 10/16.

What is the slope of a line that is perpendicular to the line 2x-4y=24

DanielleElmas [232]

Answer: y= -2x + 24

Step-by-step explanation

2x - 4y = 24

subtract 2x from both sides

divide 4y by 4y to get y by itself

then you get y= -2x + 24
