Answer: 7
Step-by-step explanation: there are 4 full circles so that equals 4. 1+1=2, 1/8+7/8=1. 4+2+1=7
Answer:
-x^2 - 7x + 4
Step-by-step explanation:
2x(x - 1) - 3x^2 - (5x - 4)
= 2x^2 - 2x - 3x^2 - 5x + 4
Adding like terms, we get:-
-x^2 - 7x + 4 (answer).
Angle four is 22 degrees because dune side interior angles are supplementary
130- 11.4
8- 2.8
144- 12
160- 12.6
I used the square root calculator on mathwarehouse.com to determine this. Hope this helps.
