If you are solving for a: it equals 3
distribute: 5a + 5=2a +14
get rid of extra number on one side: 5a=2a +9 (subtract 5 from both sides)
get rid of the other variable: 3a=9 (subtract 2a from both sides)
divide to isolate a: 3a/3=9/3 (divide by three on both sides)
answer= a=3
Answer:
x^4 - 10 x^3 + 23 x^2 + 20 x - 50
Step-by-step explanation:

You can use a bit algebraic manipulation like so
(4x+14)/(x+3)
(4x+12 + 2)/(x+3)
((4x+12) + 2)/(x+3)
(4(x+3) + 2)/(x+3)
4(x+3)/(x+3) + 2/(x+3)
4 + 2/(x+3)
2/(x+3) + 4
Answer: 16 + 55 = 71cm^2
Step-by-step explanation:
You want to divide this figure into 2 rectangles. There are two ways to do this, but either one will give you the same answer.
First One:
It has the dimensions of 5 and 11. 5 x 11 = 55cm^2
Second One:
This one wont be straightforward like the first one. You need to find these sides manually.
7 + x = 11
x = 4
Then,
9 - x = 5
x = 4
4 x 4 = 16cm^2
