Answer:
18: x=2 y=2.5
19: y = 0.5
Step-by-step explanation:
2(2)=4
2.5(2)=5
4+5=9
2×0.5=1
Answer:
15) diagonals are congruent in rectangles and squares; looks like a square
16) SW = 31
Step-by-step explanation:
since diagonals are congruent in rectangles then 'a+30' equals '2a+29'
a + 30 = 2a + 29
30 = a + 29
a = 1
SW = WU = TW = WV

Answer:
A.) Even.
Step-by-step explanation:
If a function is an even function, then
F(-x) = f(x)
Also, if a function is an odd function, then, f(-x) = -f(x)
You are given the below function
f(x) = 1 + 3x^2 − x^4
Let x = 2
Substitute 2 for x in the function
F(x) = 1 + 3(2)^2 - (2)^4
F(x) = 1 + 3(4) - 16
F(x) = 1 + 12 - 16
F(x) = -3
Also, Substitute -2 for x in the function
F(x) = 1 + 3(-2)^2 - (-2)^4
F(x) = 1 + 3(4) - 16
F(x) = 1 + 12 - 16
F(x) = -3
Since f(-x) = f(x), we can conclude that
F(x) = 1 + 3x^2 - x^4 is even
