Triangle AEB and triangle CED (second option)
Step-by-step explanation:
(a○b)(x) is the same as a(b(x)).
it is really that simple.
first you calculate the result of the inner function, and then that result is the input for the outer function.
that's it.
so,
(w○u)(2) = w(u(2))
u(2) = -2 -1 = -3
w(-3) = 2×(-3)² + 1 = 2×9 + 1 = 19
so, 19 is the first answer.
(u○w)(2) = u(w(2))
w(2) = 2×2² + 1 = 2×4 + 1 = 9
u(9) = -9 - 1 = -10
so, -10 is the second answer.
Answer:
12!!
Step-by-step explanation:
since 8 x 12 = 96 :)
Answer:
1
Step-by-step explanation:
10x + 2 = 7
10x = 7 - 2
10x = 5
x = 5/10 reduces to 1/2
2x = 2(1/2) = 1 <==
