Answer:
1)9-7+x
2+x
2)8-2x+5x
8+3x
3)-x+3x-9
2x-9
4)4x-4x-6
-6
you have to group the like terms
I hope this helps and sorry if they are wrong
You are to invent x^2, x and constant terms that sum up to specified figures.
You could begin with 6x^2-8x^2, which sums up to -2x^2.
Next, try 7x-4x, which subtract to 3x.
Last, choose two constants that sum up to 3.
Your poly? 6x^2 - *x^2 + 7x - 4x + ? + ?
Answer:
following sets of lengths can represent the measures of the sides of a right triangle? ... Q. Given ∆ABC ~ ∆LMN,
Step-by-step explanation:
I think the smallest sides correspond to the smallest angle measurement. So the smallest side would be UT and then VT and then UV.
Answer:
9/10
Step-by-step explanation:
If you are truly "struggling," you might want to consider working the problem using your calculator. It will give you a decimal answer: 0.9.
You know this is nine tenths, or 9/10 when written as a fraction.
__
When adding fractions, you are instructed to use a common denominator. Usually, that instruction is to find the "least" common denominator. In many cases, that simplifies reducing the fraction that will be the answer.
However, <em>any</em> common denominator will do. The easiest one to find is the product of the denominators. Here, that is 2·5 = 10.
The first fraction has a denominator of 2, so to make its denominator 10, you need to multiply it by 5/5.
The second fraction has a denominator of 5, so to make its denominator 10, you need to multiply it by 2/2.
__
Effectively, we have used the formula for the sum of two fractions:
(a/b) +(c/d) = (ad +bc)/(bd)
1/2 + 2/5 = (1·5 +2·2)/(2·5) = 9/10
