Answer:

y = 4(x+6)(x-2)

Step-by-step explanation:

y = 4x² + 16x - 48, factor out the 4

y = 4(x² + 4x - 12), find factors of 12

Factors of 12:

1*12, 2*6, 3*4; find a pair that sums to 4x or 4

6-2 = 4, since 12 is a negative number, a number in the factor must be negative, in this case, making 2 negative, would make 6-2 = 4

y = 4(x+6)(x-2)

Given the equation −4Square root of x minus 3 = 12, solve for x and identify if it is an extraneous solution.

Answer:

There is no solution for the given radical equation.

x = 225/16 is an extraneous solution.

Step-by-step explanation:

The given equation is

Add 3 to both sides of the equation

Squaring both sides

Divide both sides by 16

Substituting back the value of x in original equation to check the extraneous solution.

Since -18≠ 12. Hence, the value of x does not satisfy the equation.

Therefore, x = 225/16 is an extraneous solution.

Given a right triangle with the side lengths of legs = 9 and 13

For the required angle :

opposite side = 9

adjacent side = 13

so,

$\begin{gathered} \tan \theta=\frac{opposite}{adjacent}=\frac{9}{13} \\ \\ \theta=\tan ^{-1}\frac{9}{13}=34.7 \end{gathered}$

Step-by-step explanation:

as you can see they want you to find the total out of the gallons so the first thing you want to do is get 1,688 and 1,297 and multiply both of them the total is 2189336 so 1,688 x 1,297=289336
