Note that sum of triangle interior angles is 180. So,

(12x+12)+15+(3x+18)=180

15x+45=180

15x=135

x=9

Since A=12x+12=12.9+12=120

And C=3x+18=3.9+18=45

Given Information:

Principle amount = P = $6,000

Interest rate = r = 4% = 0.04

Period in years = t = 5

Required Information:

How much interest will he earn in 5 years = ?

Answer:

Amount of interest = $1,299.92

Step-by-step explanation:

Using the formula given in the question,

B = P(1 + r )^{t}

Where B is the final amount, P is the initial amount, r is the interest rate and t is the number of years

B = P(1 + r )^{t}\\\\B = 6,000(1 +  0.04)^{5}\\\\B = 7,299.92

The amount of interest earned is

Amount \:of\: interest = B - P \\\\Amount \:of \:interest = 7,299.92 - 6,000\\\\Amount \:of \:interest = 1,299.92

Therefore, Quincy has earned $1,299.92 in terms of interest by investing  $6,000 in a savings account at the rate of 4% annual interest for a period of 5 years.

Solve 4(x + 2) = 20
KiRa [710]

Answer:

x = 3

Explanation:

\sf 4(x + 2) = 20

\sf 4x + 8 = 20

\sf 4x = 20 - 8

\sf 4x = 12

\sf x = \frac{12}{4}

\sf x = 3

check:

4(x + 2) = 20

4(3 + 2) = 20

4(5) = 20

20 = 20

Hence proved x = 3
