Answer:
x=−5+√29 or x=−5−√29
Step
Let's solve your equation step-by-step.
x2+10x+10=14
Step 1: Subtract 14 from both sides.
x2+10x+10−14=14−14
x2+10x−4=0
For this equation: a=1, b=10, c=-4
1x2+10x+−4=0
Step 2: Use quadratic formula with a=1, b=10, c=-4.
x=
−b±√b2−4ac
2a
x=
−(10)±√(10)2−4(1)(−4)
2(1)
x=
−10±√116
2
x=−5+√29 or x=−5−√29
Answer:
72 spaces total
Step-by-step explanation:
The ration is 3:5. The 3 is the empty spaces which is 27. In order to simplify 27 to 3, you have to multiply it by 9. Knowing you have to simplify both sides by the same number you then multiple the 5 by 9 getting 45. The total amount of taken spaces is 45. Add the amount of empty spaces and taken spaces together you get 72 spaces total.
In my school, we do congruent statements with triangles by using SSS,ASA, SAS, etc.
For the first one, it would be SSS because the side-side-side matches up with side-side-side.
For the second one, I believe they are not similar because the lengths are corresponding between the two triangles.
Hope this helps! :)
If you need any help on triangle congruency statements, I have a flip-booklet we made in our geo class that helps a lot, and I would love to send it to you!
I think y is 2 because x is -1 right?
