I think your answer might be 19.5
Answer:
second option
Step-by-step explanation:
The perimeter P is the sum of the 3 sides, then
P = 4x² + 3 + 2x - 5 + x + 11 ← collect like terms
= 4x² + 3x + 9
Answer:
45
Step-by-step explanation:
5(4(2)+ 1²)
5(8 + 1²)
40 + 5
45
Consider the universal set U and the sets X, Y, Z. U={1,2,3,4,5,6} X={1,4,5} Y={1,2} Z={2,3,5} What is (Z⋃X′)⋂Y?
beks73 [17]
X' = U - X
= {1,2,3,4,5,6} - {1,4,5}
= {2,3,6}
(ZUX') = {2,3,5} U {2,3,6}
= {2,3,5,6}
(Z⋃X′)⋂Y = {2,3,5,6} ⋂ {1,2}
= {2}
f(x) + g(x) =
4x + 3
3x^2 + 2x - 4
----------------------------------
3x^ +6x -1
Answer: 3x^ +6x -1
