Multiply: (9x − 5)(2x2 + 12x − 3)
a) 18x3 + 98x2 − 87x + 15
b) 18x3 + 98x2 − 33x + 15
c) 18x3 + 118x2 − 87x + 15
d) 18x3 − 98x2 − 87x − 15

A) is your answer

Step-by-step explanation:

Multiply the 2x by 9x

then you take the second variable in the second equation and mulitply it by 9x. giving you 98 x squared

THEN you take 9x times Negative 3 and get -87

AND NEGATIVE 5 TIMES NEGATIVE 3 IS

POSTIVE   15

answer: bea's uncle is 25 years old.

step-by-step explanation:

given the equation , we can say that the variable "x" represents the age of bea's uncle. then to find his age, we need to solve for "x":

we must add 15 to both sides of the equation:

now we need to divide both sides of the equation by 3:

therefore, we can conclude that bea's uncle is 25 years old.
