Hey there,
The question given is as follows:
- (3x² - 4x + 8) + (-x² - 2x - 8)
When we add polynomials we add like terms (e.x. we add 3x² with -x²) and combine the two to make one polynomial. When we add the two polynomials given above:
So our answer to the problem would be 2x² - 6x.
Hope I helped,
Amna
Answer: the numerator is the top number(s) and the denominator is the bottom number(s)
Step-by-step explanation:
$25.99x
Step-by-step explanation:
As, for 1 song = $0.99 + $25
So, 1 song = $25.99
So, x song = $25.99 multiplied by x
Which is = $25.99x
So answer = $25.99x
First combine like terms.
4n-2n = 2n
now it's a one step equation:
2n=18
divide both sides by 2
n=9
Answer:
135
Step-by-step explanation:
Okay so we know that all angles in tringle sums up to 180
Therefore ∠2 = 180 - ∠1 - ∠3 = 180 - 35 - 100 = 45deg
We also know that angles on a straight line add up to 180deg as well
Therefore ∠4 = 180 - ∠2 = 180 - 45 = 135deg
