Will mark brainliest!!
Delvig [45]

Answer:

  • 2
  • 2x + 1

Step-by-step explanation:

It usually works best for factoring to remove any common factors from the coefficients. Here, they are all even numbers, so have a common factor of 2. After taking that out, you have ...

  2(4x² -4x -3)

To factor this, you are looking for factors of (4)(-3) that have a sum of -4.

  -12 = 1(-12) = 2(-6) = 3(-4)

These pairs have sums of -11, -4, -1. So, we are interested in the factors 2 and -6. We can use those to rewrite the middle term, then factor by pairing.

  = 2(4x² +2x -6x -3) = 2((2x(2x+1) -3(2x+1)) = 2(2x -3)(2x +1)

Of these, the factors that are on your list of choices are ...

  • 2
  • 2x + 1

A saleswoman earns 20% commision on all the merchandise that she sells. Last month she sold $900 worth of merchandise. How much
KengaRu [80]

Given:

Last month sales = $900

Rate of commission = 20%

To find:

How much commission (in dollars) did she earn last month?

Solution:

We have, 20% rate of commission. So, the commission for the last month is equal to 20% of last month sales $900.

\text{Commission}=\dfrac{20}{100}\times 900

\text{Commission}=20\times 9

\text{Commission}=180

Therefore, the commission for the last month is $180.
