<u>Answer</u>

a³ - a² - 3a + 6


<u>Explanation</u>

The equation requires you to subtract the two expressions.

(a³ - 2a) - (a² + a - 6)

In such an expression we subtract the like term only.

(a³ - 2a) - (a² + a - 6) =  a³ - 2a - a² - a + 6

                                  = a³ - a² -2a - a + 6

                                  = a³ - a² - 3a + 6

a girl wants to count the steps of a moving escalator which is going up. if she is going up on it, she counts 60 steps. if she i
Leto [7]

Let

x--------> the speed of the girl in step

y--------> the speed of the escalator in step

d------> the distance between ground and floor.

we know that

speed=\frac{distance}{time} \\ \\ time=\frac{distance}{speed}

when the girl is going up on escalator

x-y=\frac{d}{60} ----> equation 1

when the girl is going down on escalator

x+y=\frac{d}{90} -------> equation 2

Adds equation 1 and equation 2

2x=\frac{d}{60} +\frac{d}{90} \\ \\ 2x=\frac{5}{180} d

x=\frac{5}{360}d --------> equation 3

Time to climb (in step) with y=0 (escalator standing still)

x*t=d\\\\ t=\frac{d}{x} -----> equation 4

Substitute equation 3 in equation 4

t=\frac{d}{\frac{5d}{360}}  \\ \\ t=\frac{360}{5} \\ \\ t=72 steps

therefore

the answer is

72 steps

Matthew has $1,500 in his savings account. Currently, he pays $20 each month for an
____ [38]

Answer: 30 months

Step-by-step explanation:

Hi, to answer this question we have to write an equation:

Matthew's saving account money (1500) must be equal to the product of the amount he pays per month for the app subscription  (20) and the number of months (x); plus the product of the amount he pays per month for the Italian restaurant subscription  (30) and the number of months (x).

1500= 20x+30x

Solving for x:

1500=50x

1500/50 =x

30 months =x
