Answer:
510.84 ft²
Step-by-step explanation:
Given that,
dimensions of wall = 12.9ft by 9.9ft
height of wall = 12.9ft
width of wall = 9.9ft
there are total 4 walls in a bedroom to be painted blue.
Formula to calculate area of one wall
<h3>Height x Width</h3>
Formula to calculate area of four walls
<h3>4 (Height x Width)</h3>
= 4( 12.9ft x 9.9ft)
= 4 (127.71 ft²)
= 510.84 ft²
So area Alyssa will paint = 510.84 ft²
<em>(assuming she will paint only wall s of her room not the ceiling)</em>

By using these measurements and drawing out a triangle, you have two sides “a” and “b” and are trying to find “c”. using pythagorean theorem you can determine that “a^2 + b^2 = c^2”. plug in your distances (20 and 14) and you get 24.4 as your distance.
The answer is translation
Slope-intercept form:
y = mx + b
"m" is the slope, "b" is the y-intercept (the y value when x = 0, or (0,y))
For lines to be parallel, their slopes have to be the SAME.
The given line's slope is 4, so the parallel line's slope is also 4.
y = 4x + b
To find "b", plug in the point (-3,5) into the equation.
y = 4x + b
5 = 4(-3) + b
5 = -12 + b Add 12 on both sides
17 = b
y = 4x + 17
Answer:
Step-by-step explanation:
Another way to solve would be to distribute first:
22 = 2(x + 6)
22 = 2x + 12
Subtract 12:
22 - 12 = 2x - 12
10 = 2x
Divide by 2:
10 / 2 = 2x / 2
5 = x
