First, you would add 9x to both sides so that you get:
x^2 + 9x + 20 = 0.
Then, you want to factor. You want coefficients of x that add to 9 and have the constants add to 20:
(x + 5) * (x + 4) = 0
The answer is (C).
Answer:
1.2w = 16.2
Step-by-step explanation:
Add both sides of the equation by 3.8
Your option is C due to the fact that your question asks for a cube with 4 length, width, and height.
The area of a cube is L x W x H
The third option would be 4 x 4 x 4 = 64
Option 3, or C would be the answer
Hope this helps
Answer:
|-a|=|a|
Step-by-step explanation:
The lines beside the a's mean that you are trying to find the absolute value of what's inside. The absolute value of something is the distance it is from 0. You can't have a negative distance so anything inside of absolute value line are positive.
Therefor this is how we can solve this.
|-a| __ |a|
a __ a
a=a
Swap the sides so that all the terms of the variables are on the left side
x2+3=y
Subtract 3 from both sides
x2=y-3
