Step-by-step explanation:
40% × 12 = 4.8
12 + 4.8 = 16.8
rounded off = 17 games
Answer:
h = sqrt(96)
Step-by-step explanation:
We can use the pythagorean theorem
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
2^2 + h^2 = 10^2
4 + h^2 = 100
h^2 = 100-4
h^2 = 96
Taking the square root of each side
h = sqrt(96)
Answer:
10x^3 - 34x^2 + 33x - 7
Step-by-step explanation:
Multiply each term of the trinomial by each term of the binomial. Then combine like terms.
(2x^2 - 4x + 1)(5x - 7) =
= 10x^3 - 14x^2 - 20x^2 + 28x + 5x - 7
= 10x^3 - 34x^2 + 33x - 7
