Answer:
16
Step-by-step explanation:
h(-3)=(-3) 2 -3(-3)+5= put it all in the calculator and it gives you 16
^ ^
-3 -3
2/5 * 4= 8/5 or 1 3/5 which is ur answer
3(1+1/2) + 5(1+3/4) + 4(2) + 2(2+1/8) + 1(2+3/8)= answer. It is a lot of work depending on what you can use to solve it!
Answer:
329/9, the answer seems wrong but I triple checked because I thought so too. The answer is 100% correct
Step-by-step explanation:
Angle EFG + Angle FGH + Angle GEF = 180 degrees
(2x+1) + (6x+2) + (x + 19) = 180 degrees
9x + 22 = 180 degrees
9x = 158 degrees
x= 158/9
x+19 = Angle GEF
158/9 + 19 = Angle GEF
329/9 =Angle GEF
Double check:
(2x+1) + (6x+2) + (x + 19), x=158/9
2(158/9) + 1 = 325/9
6(158/9) +2 = 322/3
(158/9) +19 = 329/9
325/9 + 322/3 + 329/9 = 180
The difference of this problem is 90 .
