Determine the coefficient of x^4 in the expansion (2+x)^5

your coefficient would be 5

Step-by-step explanation:

the whole equation is raised to the 5th power which means that 2 becomes 32 and x turns into 5x, so your coefficient is the number next to a variable in this case that is 5.

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:

3/5

step-by-step explanation:

double number line is not a standard concept, so it must have been defined in your textbook. assume top line is numerator.
