Multiply the values of a and c together;
9*30= 270 <— find prime factors of this
270= 3*3*3*5*2
Now find a way to add these factors in different ways to give 33 (b value)
We can try (3*3*2)+(3*5)=?
18+15=33
Now that you know the numbers, break down the b value.
9x^2+18x+15x+30
9x(x+2)+15(x+2) <— make sure the brackets are the same
(9x+15)(x+2) <— check if this expands to the initial answer
Hope I helped :)
Graphs are used to represent real life situations
- Point (1, 0.75) represents 1 cookie costs $0.75
- Point (0,0) represents 0 cookie costs $0
The x and the y coordinates of the graph are used to represent the following variables
- x : The number of cookies
- y : The cost of the number of cookies
This means that:
Point (1, 0.75) represents 1 cookie costs $0.75 and point (0,0) represents 0 cookie costs $0

Answer:
Step-by-step explanation:
To write the factored form, multiply a*c from the standard form . Here it is 4*1 = 4.
Then find factors of 4 that add to b=-4.
4: 1,2,4
-2+-2 = -4
Split the middle term into -2x+-2x and factor by grouping.

Answer:
D
Step-by-step explanation:
The "Let something else figure this out answer" should be attempted with a graph. Start with the graph of f(x) = (x)^(1/3)
When you have that, you know that the graph has been shift right 1 unit which means that you are after g(x) = (x - 1)^(1/3) which means that only B or D can be correct, but which is it. The difference between the two is the minus sign. Is it g(x) = (x - 1)^(1/3) or is it g(x) = -(x - 1)^(1/3)? It turns out that it is g(x) = - (x - 1)^(1/3) because that creates a reflection across the x axis.
The graph is a bit confusing because I've chosen to put all three graphs on the same axis, which is not the clearest thing to do. But if you study it carefully you'll see which is the answer.
Red: f(x) = (x)^(1/3)
Blue: g(x) = (x - 1)^(1/3)
green:g(x) = -(x - 1)^(1/3) [ Closest to your given graph]
Answer: Green (D)
