Answer: −(b+4)(2b−3)

Step-by-step explanation:

1. Factor out the negative sign.

−(2b^2+5b−12)

2. Split the second term in 2b^2+5b−12 into two terms.

−(2b^2+8b−3b−12)

3.Factor out common terms in the first two terms, then in the last two terms.

−(2b(b+4)−3(b+4))

4. Factor out the common term b+4b+4b+4.

−(b+4)(2b−3)

Elanso [62]

Answer:

30, 30, 32, 32, 34, 38, 38, 38. Thats how you first need to set it up then what you do is add them all up which would equal to 272. Then you take 272 dived by how many numbers there are (theres 8 numbers) so you do 272/8 which would be 34! So 34 would be your answer.

URGENT!! I NEED HELP ASAP NOT ROCKY
Anestetic [448]

Answer:

  • $9000

Step-by-step explanation:

<u>Given</u>

  • Monthly payment P = $300
  • Time t = 3 years = 36 months
  • Number of payments n = 36
  • Interest rate r = 12% PA = 1% per month = 0.01 times

<u>Use loan payment formula:</u>

  • P = r(PV) / (1 - (1 + r)⁻ⁿ),
  • where P- monthly payment, PV - present value (amount of the loan), r -rate of interest, n- number of payments

<u>Substitute values and solve for PV:</u>

  • 300 = (0.01*PV) / (1 - (1 + 0.01)⁻³⁶)
  • PV = 300*(1 - 1.01⁻³⁶ )/ 0.01
  • PV = 9032.25 ≈ $9000 (rounded to the nearest hundred dollars)

Which of the following absolute value equations has no solutions?Group of answer choices
Amiraneli [1.4K]

The absolute value measures the distance a number is away from the origin (zero) on the number line. A number can be to the left or right of zero on the number line, but the distance away from zero is always positive. Graphically:

In other words:

• If d is positive and

\begin{gathered} |x|=d \\ \text{ then} \\ x=d\text{ or }x=-d \end{gathered}

• If d is negative and

\begin{gathered} |x|=-d \\ \text{then} \\ \text{ No solution, because distance (d) can not be negative.} \end{gathered}

Therefore, the equation that has no solutions is:

\boldsymbol{|x|=-3}
