Answer:

#1. The correct answer is C. 5b²-b-2

#2. The correct answer is A. 4x-5

Step-by-step explanation:

#1. (5b²-3b+2)+(2b-4), combine like terms. ----->  5b² doesn't have any like terms, so you would move onto -3b and 2b, -3+2= -1 or in other words, just b. Now move onto +2 and -4, 2+-4= -2. So, your answer would be 5b²-b-2.

#2. (6x-3)-(2x-2), also, combine like terms here. -------> 6x has a like term in the other set of parenthesis, 2x. So, you would subtract 6-2= 4, and you would now have 4x. Same thing with -3 and -2. -3-2= -5. So, now your answer would be 4x-5.

<em>Hope this helped you understand!! (:</em>

Kamila [148]

Answer: $509

Step-by-step explanation:

Given : Gabe is getting married in three years and wants to save $20,000 for his wedding. He opens an account earning 6% interest, compounded monthly.

According to the given description, we have

A= $20,000 , r= 6%=0.06 , t= 3 years , n= 12  [1 yearn = 12 months]

Formula to find Periodic monthly deposit :-

P=\dfrac{A\left(\dfrac{r}{n}\right)}{\left(1+\dfrac{r}{n}\right)^{\left(n\cdot t\right)}-1}

Substitute given values in the above formula , we get

P=\dfrac{20000\left(\dfrac{0.06}{12}\right)}{\left(1+\dfrac{0.06}{12}\right)^{\left(3\cdot12\right)}-1}\\\\=\dfrac{100}{1.19668052482-1}\\\\=\dfrac{100}{0.19668052482}=508.438749031\approx509

Hence, the  periodic monthly deposit (payment) needed to achieve a balance of $20,000 after three years= $509.
