Answer:multiply both numbers in the parenthesis by the number outside:

2n+4 +10=4n+20

add all like terms

2n+14=4n+20

subtract both sides by 14 and 4

2n-4n = 20 - 14

add or subtract like terms

-2n = 6

divide both sides by -2

n = -3

A man is trying to calculate the shadow of a 24 flag pole. He uses similar triangles by comparing his own height 5 ft to the len
Pie

Answer:

The answer to your question is 12 ft

Step-by-step explanation:

Data

Height of the flag pole = 24

shadow of the flag pole = x

height of the man = 5 ft

shadow of the man = 2.5 ft

Process

1.- Use the Thales' theorem to solve this problem

shadow of the flag pole/height of the flag pole = shadow of the man/height

                                                                                                 of the man

- Substitution

                     x/24 = 2.5/5

- Solve for x

                    x = 2.5(24)/5

- Simplification

                    x = 60/5

-Result

                   x = 12 ft

The formula is
A=p (1+r)^t
A future value?
P present value 4000
R interest rate 0.06
T time 7 years
A=4,000×(1+0.06)^(7)
A=6,014.52

Interest earned=A-p
6,014.52−4,000=2,014.52
