Answer:

$x^{3} -13x^{} -12$

Step-by-step explanation:

(x+1) (x−4) (x+3)

= ((x+1)(x−4)) (x+3)

= ((x+1)(x−4)) (x)+((x+1)(x−4)) (3)

= $x^{3} -3x^{2} -4x^{} +3x^{2} -9x^{} -12$

= $x^{3} -13x^{} -12$

Calculate the total installment price the carrying charges in the number of months needed to save them money at the monthly rate

masha68 [24]

Answer:

the total installment is $936
the carrying charges are $186
the monthly rate to buy the items are 19.23 or 20 months

Step-by-step explanation:

$39 for 24 months comes to ...

$39 × 24 = $936

The "carrying charges" are the difference between the cash price and the installment price:

$936 -750 = $186

Saving at the rate of $39 per month, it would take ...

$750/$39 = 19.23 months about 20 months to save up the cash price.

Often, such savings would come from a once-a-month paycheck, so it would take more than 19 such paychecks to save the required amount.

hope it will help :)

Please help ASAP!!!??

Answer:

$\{-2,-1,1,2,4\}$

Step-by-step explanation:

Given

The attached graph

Required

Determine the range of the graph

First, we list out the coordinate of each point on the graph:

The points are:

$\{(-4,-1),(-3,-2),(-2,2),(1,1),(2,4)\}$

A function has the form: (x,y)

Where

y = range:

From the coordinate points above,

$y = \{-1,-2,2,1,4\}$

Order from least to greatest"

$y = \{-2,-1,1,2,4\}$

Hence, the range are: $\{-2,-1,1,2,4\}$
