Step-by-step explanation:

x^3+7x^2+5x^2+35x

= x^3+12x^2+35x

x³ + 12x² + 35x

Step-by-step explanation:

"What is (x² + 5x) multiplied by (x + 7)?

First, we can convert this into an algebraic expression!

This can be written as:

(x² + 5x)(x + 7)

We can use the FOIL Method for multiplying binomials.

FOIL: First, Outer, Inner, Last

"A technique for distributing two binomials. The letters FOIL stand for First, Outer, Inner, Last. First means multiply the terms which occur first in each binomial. Then Outer means multiply the outermost terms in the product. Inner means multiply the innermost terms in the product, Last means multiply the terms which occur last in each binomial."

FOIL: First: x² × x

x² × x = x³

FOIL: Outer: x² × 7

x² × 7 = 7x²

FOIL: Inner: 5x × x

5x × x = 5x²

FOIL: Last: 5x × 7

5x × 7 = 35x

Add Everything Together!

x³ + 7x² + 5x² + 35x

Simplify:

x³ + 12x² + 35x

answer: given that the roller coaster can accommodate 1600 riders per hour, thus the roller coaster can accomodate 1600 / 60 = 26.67 riders per minute.

given that there are 345 people in the line, the number of minutes it will take for the 345 persons to get into the roller coaster is given by 345 / 26.67 = 12.94 minutes.

therefore, it will take you 12.94 minutes to get to the front of the line.

step-by-step explanation:

i think this could be a possible answer (1 / 84) -1

good luck! : d
