Answer:

56

Step-by-step explanation:

The triangular prism has 5 sides. We will find the area of each individual side and add them together.

Sides 1 and 2: The triangles

These triangles have base 6 and height 4. Use the area of a triangle formula A=1/2*base*height=1/2*6*4 = 12 to get the area of each one.

Sides 3 and 4: The rectangular sides other than the base

These are rectangles with length 5 and width 2. A = 10.

Side 5: The base

This is a rectangle of length 6 and width 2. A = 12.

Adding it all up:

12+12+10+10+12 = 56.

4 algebra 1 questions if you know the answers please try to get me to understand
asambeis [7]

Distribute each term in one parenthesis to the other terms in the other parenthesis.

(x - 2) (2x + 3)

First, distribute x. When distributing, multiply

x(2x) = 2x²

x(3) = 3x

Next, distribute the other term, -2. Remember to change the signs.

-2(2x) = -4x

-2(3) = -6

-------------------------------------------------------------------------------------------------------------------

2x² + 3x - 4x - 6

Combine like terms

3x - 4x = -x

2x² - x - 6

-------------------------------------------------------------------------------------------------------------------

2x² - x - 6 is your answer

hope this helps

Tell the error and leave if you disagree or agree.​
Musya8 [376]

Answer:

Step-by-step explanation:

9. disagree;

error: he should have divided 60 by 4, not subtracted. So the correct answer is x = 15.

10. disagree;

error: it should be 3x + 2 = 127 (opposite angles)

so x = 125/3

Can someone explain these questions? Thank you so much.

3) There are 12 inches in a foot, so 144/12 equals 12 feet- the distance above the floor. 12 goes into 40 about 3 times. 3 feet + 12 feet equals about 15 feet.

4) When you want to find the percentage of something, you would take the percentage and move the decimal place two spaces to the left. So 45% becomes .45. Then you would multiply that by the number of houses. .45 times 36 equals 16.2. Rounded to the nearest whole number, 16 houses display holiday lighting.
