Answer:

768 in²

Step-by-step explanation:

Surface Area = 2(15*14) + 2(15*6) + 2(14*6)

Surface Area = 2(210 + 90 + 84)

Surface Area = 2(384)

Surface Area = 768

Multiply the two binomials 6x - 5 and 2x + 3 and write your answer in simplified terms

puteri [66]

Answer:

x = 2

Step-by-step explanation:

6x + -5 = 2x + 3

-5 + 6x = 2x + 3

-5 + 6x = 3 + 2x

-5 + 6x + -2x = 3 + 2x + -2x

-5 + 4x = 3 + 2x + -2x

-5 + 4x = 3 + 0

-5 + 4x = 3

-5 + 5 + 4x = 3 + 5

0 + 4x = 3 + 5

4x = 3 + 5

4x = 8

x = 2

Please help me , I have been try to solve it for 2 hours. thank you very much.

Alexxandr [17]

Answer:

See the three answers with their explanation below

Explanation:

a. To eliminate the fraction from each side you multiply both sides by the least common denominator of the fractions of the two sides.

In this case it is 2×3 = 6

See how you do it:

$6\times \frac{1}{2}(x-4)=6\times \frac{1}{3}x+6\times 2\\ \\ 3(x-4)=2x+12$

b. This word problem would lead to the given equation:

Half the age of Alice 4 years ago equals 2 more than one third of her current age.

Current age: x
Age four years ago: x - 4
Half the age of Alice four years ago: $\frac{1}{2}(x-4)$

2 more than one third of her current age: $2+\frac{1}{3}x=\frac{1}{3}x+2$

Equality condition:

$\frac{1}{2}(x-4)=\frac{1}{3}x+2$

c. Solution

$\frac{1}{2}(x-4)=\frac{1}{3}x+2\\ \\ 3(x-4)=2x+12\\ \\ 3x-12=2x+12\\ \\ x=24$

Meaning: Alice is currently 24 years old.

The mean age of 5 people in a room is 25 years.

Schach [20]

Answer:

37 years

Step-by-step explanation:

If the mean age of 5 people in that room was 25 years,

∴ Sum₍₅₎= (25×5)years

= 125 years

When a person enters that room, the mean age was now 27.

∴ Sum₍₆₎=(27×6) years

= 162 years

∴ The age of the person who entered the room = Sum₍₆₎ - Sum₍₅₎

= (162-125) years

= 37 years

∴ The age of the person who entered the room is 37 years.

Hope this helps!!!
