Answer:

Step-by-step explanation:

(x + 3)^2 – 3(x + 3) - 10 = (x + 3) (x + 3) – 3(x + 3) - 10

        = (x + 3) [ (x+ 3) - 3 ] -10

       =  (x + 3 ) [ x + 3 - 3 ]  - 10

        =  (x + 3) * x - 10 = x² + 3x -10

        =  x² -2x + 5x -10

        = x ( x - 2) + 5 (x- 2)

        = (x-2) (x+5)

Answer:

(X+2) and (X-5)

Step-by-step explanation: (X+3)*x-3(X+3)-10

=(X*2+6X+9)-(3X+9)-10

=X*2+6X+9-3X-9-10

=X*2+3X-10

X=(-b+/-(b*2-4ac)*1/2)/2a

a=1, b=3, c=-10

=-3+/-((3)*x-4(1)9-10))*1/2/2(1)

=-3+/-(9+40)/2

=(-3+/-7)2

Therefore 1. (-3-7)/2, and 2. ((-3+7))/2

1. -10/2=-5, X=-5 therefore (X+5)

2. (4/2)=2, X=2 therefore (X-2)

Lucy needs to hire a host. Host A is offering his services for an initial $60 in addition to $13.25 per hour. Hostess B is offer
Oksanka [162]

Host A: 60+13.25h

Host B: 75+11.5h

60+13.25h =75+11.25h

subtract 11.25h from each side

60+2h = 75

subtract 60 from each side

2h = 15

divide by 2

h = 7.5

at 7.5 hours the two hosts will charge the same

Anisha invested $8,000 in an account that earns 10% interest How much money will she have in 15 years of the interest is compoun
tamaranim1 [39]

Answer:

A = $35,198.32

Step-by-step explanation:

<em>Use the formula to calculate compound interest</em>:

A = P(1 + i)ⁿ

"A" for total amount after the time period

"P" for principal, or starting money

"i" for the interest rate in a compounding period

To calculate "i":

i = r / c

"n" for the number of compounding periods

To calculate "n":

n = tc

So, we can <u>combine the formulas</u> into:

A = P(1+\frac{r}{c})^{tc}

"c" is the compounding periods in a year. (quarterly = 4)

<u>We know</u>:

P = 8000

r = 10% / 100 = 0.1

t = 15

c = 4

<u>Substitute the information in the formula</u>.

A = P(1+\frac{r}{c})^{tc}

A = 8000(1+\frac{0.1}{4})^{15*4}      Solve "i" and "n"

A = 8000(1+0.025)^{60}        Solve inside the brackets

A = 8000(1.025)^{60}         Do the exponent before multiplying by 8000

A = 35198.318             Exact answer

A ≈ 35198.32              Round to two decimal places for money

Therefore she will have $35,198.32 after 15 years.
