I would reccomend using the rainbow method for this since there is a number infront of x^2 

1. Find your magic number   Multiply 12 * -4  = -48 
2. You want a number that multiplies to -48 but adds to 2 
12   -4    + 8
8     -6     +2   This is it. 
3. Substitute those numbers for your middle number 
12x^2 -6x + 8x -4   
4. Factor by grouping
(12x^2 -6x) + (8x-4) 
5. Pull out GCF 
6x(2x-1)  +  4(2x-1) 
(6x+4)(2x-1)

Plz help me .. I am really stumped!!!!!!! part of the set for a play is a big triangular piece of plywood. the area of the trian
saul85 [17]
The way to find the area of a triangle is A=\frac{B*H}{2}
if the base is 3 feet longer then the height we can write it like this B=H+3

now we can add it to our area equation
20=\frac{H(H+3)}{2}
20=\frac{ h^{2} +3h}{2}
40=H^{2}+3H
10\frac{1}{3}=H^{2}
h=3.2ft

What is the value of the function at x = 3?<br><br> Enter your answer in the box.
butalik [34]

Answer:

4

Step-by-step explanation:

Recall a linear function, is a line on a graph made up of an infinite amount of points which satisfy the relationship. That means at x=3 there is a specific point on the line with an output. The value of a function at x=3 asks, what is the output y value for the input x value?

To find it, we locate 3 on the x-axis. We draw a vertical line directly to the line following the grid line. We mark the point on the line. We then draw a horizontal line directly to the y-axis following the grid line. The point we hit on the y-axis is the value of the function.

Here it is 4.
