Answer:
10s²-6s+9
Step-by-step explanation:
C = -3 + 5s²
B = -2s + 5
2(-3 + 5s²) = -6 + 10s²
3(-2s + 5) = -6s + 15
10s² - 6s + 9
Answer:
114
Step-by-step explanation:
if,
24inches=72cents
38inches=?
we cross multiplication,
38times72=2736 divide with 24=114
The answer is114
The value of x that will make the statement true is 1
Step-by-step explanation:
The given is:
- f(x) = x - 4
- g(x) = 2x + 3
We need to find the value of x which makes [f(x) + 2g(x)] = 7
∵ f(x) = x - 4
∵ g(x) = 2x + 3
∵ f(x) + 2g(x) = 7
- Multiply g(x) by 2
∵ 2g(x) = 2(2x + 3) = 2(2x) + 2(3) = 4x + 6
∴ 2g(x) = 4x + 6
∵ f(x) + 2g(x) = 7
∴ (x - 4) + (4x + 6) = 7
- Add the like terms in the left hand side
∴ (x + 4x) + (-4 + 6) = 7
∴ 5x + 2 = 7
- Subtract 2 from both sides
∴ 5x = 5
- Divide both sides by 5
∴ x = 1
The value of x that will make the statement true is 1

Answer: 3x2 + 3x - 7
Step-by-step explanation: The first term is, 3x2 its coefficient is 3
The middle term is, +3x its coefficient is 3
The last term, the constant, is -7
1.Multiply the coefficient of the first term by the constant 3 times -7 = -21
2. Find two factors of -21 whose sum equals the coefficient of the middle term, which is 3
