18 should be the answer if not I’m sorry I just need this as a step
Same height when both equations are equal
-16x^2 + 74x + 9 = -16x^2 + 82x
82x - 74x = 9
8x = 9
x = 9/8
x = 1.125
x = 1.13 ---->rounded to nearest hundredths of seconds
answer
1.13 seconds
•*Ok first let me show you the formula for the Area of the trapezoid.
A=a+b/2 h.(I will be using the letter x for the multiplication sign)
*And here is the formula to find the height of a trapezoid
h=2 x A/a+b (2 times the Area over base "a" plus base "b")
*We need to plug in the numbers: h = 2 x 136.5/6+15
*Next, we add the two bases to get 21: 6+15=21 (h=2 x 136.5)
*Then, divide the total of the two bases (21) from the area to get 6.5: 136.5/21-6.5
*Finally we multiply 2 by 6.5: 2 x 6.5= 13
The height if this trapezoid is 13.
Hope this helps you ☺

MN=9.1 cm
LM= 9.9 cm
Step-by-step explanation:
Answer:
all of them are valid solutions
Step-by-step explanation:
So we plug in values of t below and get:
18 is < 107
54 is < 107
36 is < 107
27 is <107
