Answer:Area)=12x(Base)x(Height)Step-by-step explanation:
Answer:
m=1
Step-by-step explanation:
add 6 to both sides, 9=9m
divide 9 on both sides, m=1
Answer:
x = 3 and 7
There are two true solutions.
Step-by-step explanation:
To solve
, use inverse operations by squaring both sides of the equal sign.
![(x-7)^2 = (\sqrt{-4x+28})^2\\x^2-14x+49 = -4x+28\\x^2-14x+4x+49-28 = 0\\x^2-10x+21=0](https://tex.z-dn.net/?f=%28x-7%29%5E2%20%3D%20%28%5Csqrt%7B-4x%2B28%7D%29%5E2%5C%5Cx%5E2-14x%2B49%20%3D%20-4x%2B28%5C%5Cx%5E2-14x%2B4x%2B49-28%20%3D%200%5C%5Cx%5E2-10x%2B21%3D0)
The quadratic expression can be factored into binomials and set equal to 0 by the zero product property to find x.
(x - 3) ( x - 7) = 0
x-3 = 0 so x=3
x-7 = 0 so x=7
Now check each solution into the original equation to be sure it solve the solution and is not extraneous.
![7-7 = \sqrt{-4(7)+28}\\ 0=0](https://tex.z-dn.net/?f=7-7%20%3D%20%5Csqrt%7B-4%287%29%2B28%7D%5C%5C%200%3D0)

The correct answer is that "Dish A has a greater rate of change."
In Dish A, the values are going up by 2 each day. In Dish B, the values are staying the same.
Therefore, Dish A has a greater rate of change.
