F(x) = f(p)
f(p) = x^2 -1
your answer is f(p) = p^2 -1
hope you understand what i have done.
4y + 8x = 112
V = x*x*y= x^2y
y + 2 x = 28
y = 28 - 2x
V = x^2 (28-2x) = 28 x^2 - 2 x^3
Answer:
Step-by-step explanation:
let width=x
length=3x
area=3x×x=3x²
3x²=192
x²=192/3=64
x=√64=8
width=8 m
length=3×8=24 m
Cross multiply the fractions as in 20 times D and 13 times 60 and the problem will be 20d = 780. Here you can divide 780 by 20 and the answer is what D equals to.

AnswerS :
1. Tan Z = p / b = 21/28
2. Cos C = b / h = 16 / 34 = 8/17
3. Sin C = p/ h = 28/35
4. Tan X = p / b = 32/24 = 16 / 12
5. cos A = b / h = 30/34 = 15 / 17
6. Sin A = p / h = 32/40 = 16/20
7. sin Z = p / h = 24 / 40 = 12 / 20
8. sin C = p / h = 14 / 50 = 7 / 25

- Sin θ = Perpendicular / Height
- Tan θ = Perpendicular / Base
