Step-by-step explanation:
Area of a rectangle is base times height.
A = bh
A = (12 in) (2.5 in)
A = 30 in²
Step-by-step explanation:
1.Get the equation in the form y = ax2 + bx + c.
2.Calculate -b / 2a. This is the x-coordinate of the vertex.
3.To find the y-coordinate of the vertex, simply plug the value of -b / 2a into the equation for x and solve for y. This is the y-coordinate of the vertex.

Answer:
x=-5
Step-by-step explanation:
Add 22x to both sides: -8x+100=140
Subtract 100 from both sides: -8x=40
Divide both sides by -8: x=-5
So the answer is x=-5
