I think it would be 4x^2 and 3x^3 because they both have the same "x". Because you can't add, for example, 5x + 7z, they aren't alike. That's why you have to choose like terms, for example, 5x+ 5x= 10x.
If you want to add fractions, you need to first make them like fractions, this means both fractions need to have the same denominator without changing its proportion:
7/10 = 70/100
17/100 = 17/100
Now it is the same and you can add them now because they are like fractions.
70/100 + 17/100 = 87/100
Your answer is B.
Since one of the 5 vowels is paired with the four card suit.so our answer is just 5+5+5+5=20
Answer:
10x²+11-2x
Step-by-step explanation:
I hope you mean 7x²+8+5, not 7x²+8x+5.
We need to combine like terms. Anything with squared should be added together, et cetera.
(7x²+8+5)+(3x²-2x-2)
You can take out the parenthesis, because they don't matter in addition.
7x²+8+5+3x²-2x-2
Add the terms, step by step. Each bold pair needs to be added together.
7x²+8+5+3x²-2x-2
10x²+8+5-2x-2
10x²+11-2x
Now there's no more we can add together.
Add (-2X) to both sides:
2X + B + (-2X) = C + (-2X)
If we (rearrange) it into B + 2X + (-2X) = C + (-2X)
B + 2X - 2X = C + (-2X)
Since +2X - 2X = 0
B + 0 = C + (-2X)
B = C + (-2X)
B = C - 2X
