Answer:

(x+4)(x+2)

Step-by-step explanation:

Distributive property of 2 binomials:

First, outer, inner, last

(a+b)(c+d) = ac+ad+bc +bd

Factor x^2 into x*x

Factor 8 into 2*2*2

Find what two numbers add up to 6 and multiply to get 8

1 and 8 do not work because they add up to 9.  2 and 4 work because they add up to 6.  

Check: (x+4)(x+2)

First:  x*x = x^2

Outer: 2*x

Inner: 4*x

Last: 2*4 = 8

Add together: x^2+2x+4x+8 = x^2+6x+8

Natali5045456 [20]

Answer:

(-5, 3)

Step-by-step explanation:

The coordinates of the midpoint are the averages of the endpoints.

-1.5 = (x + 2) / 2

-3 = x + 2

x = -5

6 = (y + 9) / 2

12 = y + 9

y = 3

Anya's grandparents decide they want to invest at the bank. They have $35,000
Aneli [31]

Anya's parents will have $44,440.71 after 6 years if they invested in a bank.

The interest rate given is an annual rate yet will be compounded quarterly. You therefore need to convert the interest rate to a quarterly rate.

= 4% / 4 quarters

= 1% per quarter

Number of periods:

= Number of years x Number of quarters in year

= 6 x 4

= 24 quarters

The amount they will have in their account is:

<em>= Amount x ( 1 + rate) ^ number of periods </em>

= 35,000 x ( 1 + 1%)²⁴

= $44,440.71

In conclusion, they will have $44,440.71 if they invested their money in a bank for 6 years.
