Answer:

88 + 30 $\sqrt{7} \\$

Step-by-step explanation:

Expand to make easier:

(3 $\sqrt{7} \\$ + 5) x (3 $\sqrt{7} \\$ + 5)

FOIL:

9(7) + 15 $\sqrt{7}$ + 15 $\sqrt{7}$ + 25

Simplify:

63 + 30 $\sqrt{7}$ + 25

88 + 30 $\sqrt{7}$

$\frac{x}{x + 4}=\frac{3}{x - 1} \\3(x+4) = x(x-1)\\3x+12 =x^2-x\\0=x^2-4x-12\\0=(x-6)(x+2)\\X= 6, -2$

Steps:

First we cross multiply

Then Distribute,

Then move all terms to one side

If Lana deposits $500 into a savings account that gains simple interest at

Oksana_A [137]

Answer:

10 years

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 2%/100 = 0.02 per year,

then, solving our equation

t = 100 / ( 500 × 0.02 ) = 10

t = 10 years

The time required to

accumulate simple interest of $ 100.00

from a principal of $ 500.00

at an interest rate of 2% per year

is 10 years.

Distribute the 2 first.

f(n) = 2n - 2 + 3n

Combine like terms.

f(n) = 5n - 2
