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>

Answer:
Ok ill get back to you when I figure it out so see you in 5 minutes!
Answer: Hi I think that I can help you with your problem!
Let which means
Here a bar over 8 means that there the given decimal value is non terminating and there are a large numbers of 8 present after the decimal.
To solve the given non terminating decimal as fractions, we will have to eliminate the bar term from the given value.
So, we can rewrite as:
......(1)
Now, let us multiply the above with 10.
....... (2)
Now, let us subtract (1) from (2):
So, in simplified fractions:
Step-by-step explanation:
-4x > 16
Divide -4 on both sides. Don't forget to flip sign since we are dividing by a negative number.
x < -4
2y² + y - 3
(2y+3)(y-1)
2y(y-1) + 3(y-1)
2y² - 2y + 3y - 3
2y² + y - 3
2y + 3 = 0
2y = -3
y = -3/2
y = -1 1/2
y - 1 = 0
y = 1
2y² + y - 3 = 0
2(-3/2)² + (-3/2) - 3 = 0
2(9/4) - 3/2 - 3 = 0
18/4 - 3/2 - 3 = 0
18/4 - (3/2 * 2/2) - 3(4/4) = 0
18/4 - 6/4 - 12/4 = 0
(18 - 6 - 12)/4 = 0
(18 -18)/4 = 0
0/4 = 0
0 = 0
