Answer:
2.8 cm
Step-by-step explanation:
The area of a trapezoid is calculated using the formula:
where
B is the length of the major base
b is the length of the minor base
h is the height of the trapezoid
In this problem, the glass window has the shape of a trapezoid. We know that:
B = 2 cm is the length of the top base
b = 4.5 cm is the length of the bottom base
is the area of the trapezoid
Solving for h, we can find the height of the stained glass window:
Answer:
8
Step-by-step explanation:
(15-4x)+5
(15-4(3))+5
(15-12)+5
3+5=8
If h(x) = -2x - 10 you should put the -4, -2. -18, -3 or/and -16 in the place of the x in the formula.
So for example:
h(-4) = -2 * (-4) - 10 = 8 - 10 = -2
Or at least, that's what I think the answer should be.
Good luck!
