The answer will be 8.39 because the third number (8) is above 5 so you have to round up. Good luck!
(2x^2 + 16x + 30) / (5x^2 + 13x -6)
Start by factoring the numerator and denominator.
Cancel any like factors.
2(x^2 + 8x + 15)
2(x + 5)(x + 3) / (5x -2)(x + 3
2(x + 5) / (5x - 2)
The third choice
He still has 75% of his income left because 1500/375=4 so he spent 1/4 of his check and has 3/4 left.
If Mr. Koppel only has $10.00 to spend on gas, and the gas is $1.49 a gallon. We will have to divide $10 into 1.49.
10 ÷ 1.49 = 6.7
So, Mr. Koppell will be able to buy 6.7 gallons of gas with his $10.00.
Hope this helps. :)
1) Tanθ= opposite/adjacent
θ=Tan-1(9/7)
θ=52.125 = 52 degrees
2) Cosθ= adjacent/hypothesis
θ=Cos-1(5/12)
θ=65.376 = 65 degrees
