Answer:
No solutions
Step-by-step explanation:
Distribute the -1 on the left side
-1(5x+7) +1 = -5x-5
-1*5x +-1*7 +1 = -5x -5
-5x-7+1=-5x-5
Combine like terms
-5x-6=-5x-5
Add 5x on both sides
-6=-5
This statement is false, therefore there are no solutions
Hope this helps! :)
Answer:
17. angle DAB=118º
18. angle DAB=126º
Step-by-step explanation:
The angle A should be 180º-85º-33º(cause the total angle in a triangle is 180º)
So you will get 62º as the angle of A.
And what the question ask is angle of DAB,so again 180º-62º=118º(A straight line is 180º)
Same goes to question 18,use 180º to minus the two angle given,you get 54º ,and then 180ºminus 54º again,the answer is 126º
Your answer would be B. -x² - 2x + 16
If we look at the terms separately, you can add them separately, so:
4x² + -5x² = -x²
0 + -2x = -2x
9 + 7 = 16
I hope this helps!
