Answer: 2(4 + x)

Step-by-step explanation:

i just multiplied across the parentheses. we can rule out the first option, because it would multiply out to be 8 + 4x.

the second option is the one that i calculated second, so i knew that i could rule out the last one my default.

just for kicks, if we multiplied the third option, it would come out to 8 + 4x.

I need help with math xl please! See attached
Elden [556K]

I had to answer a question similar to that one on Math XL. This question was about renting a truck instead of needing a 48 mile taxi. (Took me a long time just to find the truck question, but I am giving you the truck help me answer the question, in hopes that it will help you.)

The cost of renting a truck from Hamilton Auto Rental is ​$47.60 per day plus ​$0.15 per mile. The expression 47.60 plus 0.15 m represents the cost of renting a truck for one day and driving it m miles. Evaluate 47.60 plus 0.15 m for m equals 120.


Substitute the numerical value for each variable into the expression and simplify the result.


I am sorry if that didn't help you, but it was the closest thing I could find to use to help you.

what are the solutions of the equation x4 95x2 – 500 = 0? use factoring to solve. and x = ±10 and x = ±10i and x = ±10i and x =
Andreas93 [3]

Doing factorization, we know that the factors of the given equation are ±√5 and ±10i.

<h3>What is Factorization?</h3>

In mathematics, factorization or factoring consists of writing a number or any mathematical item as a product of several factors, typically small or easier objects of the same.

For example, 3 × 5 is a factorization of an integer 15 and is a factorization of an equation x² – 4.

So, we have the equation:

x⁴ + 95x² – 500 = 0

Factorizing the above equation:

x⁴ + 100x² - 5x² - 500 = 0

x²(x² + 100) - 5(x² + 100) = 0

(x² - 5)(x² + 100) = 0

Solving further:

x² = 5

x² = -100

x = ±√5

x = √-100

Factors: ±√5 and ±10i

Therefore, doing factorization, we know that the factors of the given equation are ±√5 and ±10i.
