Answer:
72.54
Step-by-step explanation:
Use formula for trapezoid: a+b/2 * h
Step-by-step explanation:
the area is
![A=\frac{(12+12-4x)(x+2)}{2}\\=2(6-x)(x+2)\\=-2x^2+8x+24\\=-2(x^2-4x+4)+32\\=-2(x-2)^2+32](https://tex.z-dn.net/?f=%20A%3D%5Cfrac%7B%2812%2B12-4x%29%28x%2B2%29%7D%7B2%7D%3C%2Fp%3E%3Cp%3E%5C%5C%3D2%286-x%29%28x%2B2%29%3C%2Fp%3E%3Cp%3E%5C%5C%3D-2x%5E2%2B8x%2B24%3C%2Fp%3E%3Cp%3E%5C%5C%3D-2%28x%5E2-4x%2B4%29%2B32%3C%2Fp%3E%3Cp%3E%5C%5C%3D-2%28x-2%29%5E2%2B32)
will max if
a. x = 2
and the max area is
b 32
Answer:
X=13/3
Step-by-step explanation:
Distribute and transfer the x’s to the other side and make sure to flip the signs of the x’s. Then solve for x.
The statement
would best describe the line segments drawn would be they are parallel
and congruent. The correct answer between all the choices given
is the second choice or letter B. I am hoping that this answer has satisfied
your query about and it will be able to help you.
first, distribute -6 to (2b + 1), giving you -12b - 6, and then on the another side of the equation, distribute -2 to (5 + 4b) giving you, -10 - 8b. now we need to put our coefficients on one side so we will add 8b to each side of the equation, giving us -6 = -10 - 8b + 12b, then we will add 10 to both sides of the equation giving us, 10 -6 = -8b +12b, this gives u 4 = 4b. then, you would solve for b, which equals 1.
