A polynomial with roots a and b is (x - a)(x - b).

(x - 2)(x - (-1))(x - 4) = 0

(x - 2)(x + 1)(x - 4) = 0

has roots 2, -1, and 4.

Let's take a look. A baker is using three cups of water for every eight ounces of water.

Let's think of a ratio!

8 * x = 96
x =  cups of flour.


Let's solve the equation.

96 divided by 8 equals 12.

The correct answer would be D - 12 cups of flour.

Which of the following is equivalent to 7(x-5)+2(6-x)=12?
photoshop1234 [79]

Answer:

7x - 35 + 12 - 2x = 12

Step-by-step explanation:

Distribution is the first step. Multiply 7 to x and -35. And multiply 2 to 6 and -x. That gives you the answer 7x - 35 + 12 - 2x = 12.

Find the dimensions and maximum area of a rectangle, if it’s perimeter is 24 inches
Andru [333]
Perimeter = 24

triangle perimeter = 2W + 2L

24= 2W + 2L

12 = W + L

L= 12-W

AREA = W*L

AREA = (W)(12-W)
A = 12W-W^2
 
maximum occurs when you take the derivative 

d/dw=12-2w = 0 
w=6

after this i think we can say 6 * 6 = 36 is the maximum area.. not to sure, havent done a problem like this in a while

hope this helps 

or if we know what w=6 we can find L

L = 12-w which we still get 6<span />
