Which verbal expression is represented by 2(x + 4)? A. twice the sum of a number and four

B. the sum of two times a number and four

C. two times the difference of a number and four

D. twice the product of a number and four

A.

Step-by-step explanation:

The sum of a number, x, and 4 just means x + 4.

If we take twice this sum, it implies that we take the resulting number and multiply it by 2.

Our resulting number is x + 4, so we are left with 2(x + 4).

I hope this helps!

D

Step-by-step explanation:

the one that makers most sense is the last one, but i would define it as "two times some number divided by 4"

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
