Answer:
Step 2:
Part A
f(x) = a(x-h)^2 +k
Part B
I'm not really sure about this part
Part C
f(x)=-12/25(x-25)^2+32
Step 3:
Part A
y = ax^2 + bx + c
Part B
f(x) = -12/25(x - 25)^2 + 32
Part C
a = -12/25
b = 0
c = 32

Answer:
Below
Step-by-step explanation:
(2x/x+3) + (x+3/x-5)
Transform: 2x(x-5) + (x+3)^2 / (x+3)(x-5)
Remove brackets and expand : 2x^2 - 10x + x^2 + 6x + 9 / x^2 - 5x + 3x - 15
Collect like terms : 3x^2 - 4x + 9 / x^2 - 2x - 15
Final answer: 3x^2 - 4x + 9 / x^2 - 2x - 15
108
I'm not positive but i belive this is correct
Answer: 12.5
Step-by-step explanation:
you go on the web and google area of trapezium
Supplementary because the line equals 180°
(x-21)+x
2x-21=180
2x=201
×=100.5°
