Answer:
x = 14
Step-by-step explanation:
Tan 25 =
Where opposite = x, Adjacent = 30 m
=> 0.466 x 30 = x
=> x = 14
Answer:
–9(3x³ – 8x + 9)
Step-by-step explanation:
–27x³ + 72x – 81
The above equation can be factorised as follow:
–27x³ = –3 * 3 * 3 * x * x * x
72x = 2 * 2 * 2 * 3 * 3 * x
–81 = –3 * 3 * 3 * 3
Common factor = 3 * 3
Greatest common factor = 9
Thus,
–27x³ + 72x – 81 = 9(–3x³ + 8x – 9)
–27x³ + 72x – 81 = –9(3x³ – 8x + 9)
The partial products would be 10 multiply 40, 10 multiply 3, 7 multiply 40, and 7 multiply 3.

Answer:
y = 1.5x
Step-by-step explanation:
We notice that the ratio y/x is a constant: 30/20 = 3/2. Then y is proportional to x and the equation can be written ...
y = (3/2)x
