Solve the equation = a/4+a/3=21
a=36
2 1/4 ⋅ 9/5 —> 9/4 ⋅ 9/5 = 81/20 or 4 1/20 or 4.05
Answer:
1. Communitave property
2. communitave property
3.
1. distribute 2 to x and 10 to get ride of parenthesis
2. subtract 2x from the left to move it to the right so x is by itself
3. add 15 to both sides to cancel it out on one side, and move to the other.
4. divide by 5 on both sides so you can get the value of x
5. flip equation so it is in the x equals form
4.
1. distribute 2 to the x and positive 3 on the left side, also distribute -4 to both x and -1 , to get rid of our parenthesis.
2. add 4x to both sides so it cancels out on one side and moves to the other ( our xs and numbers need to be on opposite sides)
3. subtract 4 on the left side to move it to the right side because again numbers on the right and letters on the left
4. divide by 6 on both sides of the equation to solve for x
It would be the first one because if you do 4^2+4^2 it does NOT equal 32 it equals a even greater number. So the first one is not a right triangle
