Answer: See each part below.
1) A, B, and C are the coefficients in order when it equals 0. Move over the 4 and you have 5, 9, -4 or Choice B.
3) If you graph the equation, it will be above the x-axis. Therefore, it has no roots. Choice D
4) Choice A is correct. Use the coefficients: A = 4, B = 3, C = -10. Simply plug those into the quadratic equation and you will get -2 and 1.25.
How to solve:
Step 1 : Note down the given ratio from the questions.
Step 2 : <span>Find the greatest common factor, and divide the numerator and denominator by that value.

Answer:
6x + 35
Step-by-step explanation:
First Distribute
8x + 3x + 15 -5x +20
Then collect like terms
6x + 35
to solve you would need the value of x to plug it!
Answer:
B) 628.32 cm cubed
Step-by-step explanation:
we know the formula to find the volume of a cylinder is π*r^2*h
where r is the radius and h is the height.
the equation would look like this
π*5^2*8
π*25*8
π*200
628.32 cm
