Answer:

d. cost will never be the same

Step-by-step explanation:

power plus: 34.37x + 21

heavy hulk: 34.62x + 33.50 (1/2 fee: 34.62x + 16.75)

*set expressions equal to each other*

34.37x + 21 = 34.62x + 16.75 --> *subtract 34.37x from both sides*

21 = .25x + 16.75 --> *subtract 16.75 from both sides*

4.5 = .25x *divide by .25 on both sides*

18 = x

*find y by plugging in 18 for x*

34.37 (18) + 21 = 34.62 (18) + 16.75

618.66 + 21 = 623.16 + 16.75

639.66 = 639.91

<u><em>they don't equal</em></u>

Write as a product of 2 binomials and a monomial (factor out as much as possible from each binomial):
gayaneshka [121]

(14x+21y)(6ab-3a) = 3a(2b - 1)(14x + 21y)

<em><u>Solution:</u></em>

Given that,

(14x+21y)(6ab-3a)

We have to factor out terms and write as a product of 2 binomials and monomial

A monomial is a mathematical expression with only one term, while a binomial is a mathematical expression with two terms.

From given expression,

(14x+21y)(6ab-3a) = (14x + 21y)(3 \times 2ab -3a)

3 and a are common factors in second bracket

(14x+21y)(6ab-3a) = 3a(2b - 1)(14x + 21y)

Hence, the product of two binomial is written in two binomial and a monomial
