Answer:
2x(5x+1)(2x+3)=0
Step-by-step explanation:
x{20x^2+34x+6}=0
2x(10x^2+17+3)=0
2x(10x^2+15x+2x+3)=0
2x{5x(2x+3)+1(2x+3)}=0
2x(5x+1)(2x+3)=0

Answer:
7 pizzas
Step-by-step explanation:
Using the formula for slope (rise/run) we can calculate how much one pizza cost.
dollars per pizza.
Take the $11 per pizza and divide it by $80 to get 7.2727 pizzas. Since you can not have .2727 of a pizza you round down to 7 pizzas.
Rather than solve the entire problem for you, I'll give you some hints to help you get started:
1. The amplitude of your sinusoidal graph is |3|, or just 3.
2. Because of that, your graph begins at the point (0,3).
3. Because this is the cosine function, your graph descends from (0,3) to y=3 and then begins to ascend (back to y=3).
4. The coefficient of x is "one half pi," or pi/2. Call this "b".
5. The period of your function is 2pi/b. Here, b=pi/2.
Dividing, [2pi]/[pi/2] = 4.
6. Mark your horizontal axis as follows: x=0, 4, 8, 12, 16, ...
7 Draw one cycle of the cosine function with amplitude 3. It must begin at (0,3) and end at (4,3) (which covers one period).
8. Draw another cycle or two, beginning at (4,3) and ending at (8,3), and so on.
Answer:
32 black grapes
Step-by-step explanation:
3:4 is the same as 3/4 so we Know that the ratio is green to black.
There are 24 grapes which means the ratio is 24:? Now you ask yourself what is 24 3/4s of .... 32
24/32 and to check simplify
24/8
32/8
3/4 therefore this is the correct answer
(hope this helps, sorry if I didn't explain well)
