The sum of the polynomials (8x²-9y²-4x)+(x²-3y²<span>-7x) is:
1. You must add the terms whose variables and exponents are the same.
2. Let's rewrite the polynomials:
</span>
(8x²-9y²-4x)+(x²-3y²-7x)
8x²-9y²-4x+x²-3y²-7x
(8+1)x²+(-4-7)x+(-9-3)y²
3. Therefore, the result is:
9x²-11x-12y²
3. <span>What is the sum of the polynomials?
The answer is: </span>9x²-11x-12y²
Answer:
lowered by 31 feet
Step-by-step explanation:
The problem statement makes us assume the boat is lowered in each case. The boat is apparently not raised anywhere, so is lowered by ...
(12 + 11 + 8) feet = 31 feet
A 100% increase would be 18 so you just have to divide until you get the number added so from 9 to 13 is a increase of 4 so that would be around 44.44% repeating.
Here, 2x + 1 = 3x
3x - 2x = 1
x = 1
In short, Solution would be 1 only.
Hope this helps!
Answer:
10 1/4 - 2 2/4 = 37/4
Step-by-step explanation:
- 10 1/4 - 2 1/2
- 10*4+1/4 = 41/4
- (41/4) - 1 = 37/4
That answer!
