The sum of the polynomials is -11x - 3y^2.
In order to find this we must first collect all like terms. To start, we'll begin with all x^2 terms.
8x^2 - 9x^2 + x^2 = 0
Since these all cancel, we're left with no x^2 term. Next we'll do x terms.
-4x - 7x = -11x
The only thing left is -3y^2, which has no alike term. so we just include that in there.
-11x - 3y^2
2(x - 1) - (3x - 2)
First, simplify brackets. / Your problem should look like: 2(x - 1) - 3x + 2
Second, expand. / Your problem should look like: 2x - 2 - 3x + 2
Third, gather like terms. / Your problem should look like: (2x - 3x) + (-2 + 2)
Fourth, simplify. / Your problem should look like: -x
Answer: -x
Answer:
x=1
Step-by-step explanation:
We can solve this equation using a mix of simplifying and using arithmetic on both sides:
6-4x=7x-9x+4
6-4x=-2x+4
2-4x=-2x
2=2x
1=x
x=1

Answer:
b. 106 sq.cm
Step-by-step explanation:
A=L×W
A1= 2(5×8) = 2(40) = 80
A2= 2(1×8) = 2(8) = 16
A3= 2(5×1) = 2(5) = 10
Total area = 80 + 16 +10 = 106 sq. cm
