what u need help with?
Answer:
x^2-x-5
Step-by-step explanation:
1. expand the square
(+1)(+1)−3(+2)
2. distribute
(+1)+1(+1)−3(+2)
3. distribute
^2++1(+1)−3(+2)
4. multiply by 1
^2+++1−3(+2)
5. combine like terms
^2+2+1−3(+2)
6. distribute
^2+2+1−3−6
7. subtract the numbers
^2+2−5−3
8. combine like terms
^2−−5
9. gg you are done
^2−−5
First you add up all of the numbers you've been given and then you divide that sum by the number of terms you added. For example, if you were given 21, 45, 58, 66, 67, 80, and 92 you would add them all together and get 429. Then you would divide 429 by 7 (because that is the number of numbers we added together) and you would get about 61.29.
So basically
Step 1: add all numbers together
Step 2: divide sum by the number of terms.
M<S = 1/2(80-40)
m<S = 40/2
m<S = 20
answer is A. 20
Answer: 17
Step by Step:
When finding the triangle’s angles you have to know the measure of a triangle which is 180 degrees and will apply to all types of triangles. Having to say that, you have all equations and have to put them all together to equal 180 degrees, so it will be 6x + 10 + x + 17 + 4x - 34 = 180 then you combine like terms to have 11x - 7 = 180 then add 7 to both sides so it will be 11x = 187 and then divided 11 to both sides as well to have only x = 17
