Answer:
108 degrees
Step-by-step explanation:
3x+x+6x=10x, 180/10=18 and 18x6 is 108
To solve this problem you must apply the proccedure shown below:
1. You have the following expressions shown in the problem above:
(<span>8m^2-6/n+3) + (9m^2-4/n+3)
2. As you can see, they have equal denominators, then you have:
(</span><span>8m^2-6+ 9m^2-4)/(n+3)
</span><span>
3. Therefore, when you sum, you have the following result:
(17m</span>²-10)/(n+3)
<span>
The answer is: </span> (17m²-10)/(n+3)<span>
</span>
Answer:
12 inches
Step-by-step explanation:
The formula for a trapezoid is
A = 1/2(a +b)h
The formula to find the height =
h = 2A/a + b
A= 216 in²
a =14 in
b = 22 in
Hence,
h = 2 × 216/14 + 22
h = 12 inches
The height of the trapezoid = 12 inches
5 km = 5000 meters
66 minutes = 3960 seconds
Meters per second = 5000/3960 = 1.26
The answer is A.1.26
Answer:
x=13
Step-by-step explanation:
I guess the angles are supplementary,Which means they have a sum of 180°.
11x - 15+5x-13=180
16x-28=180
16x=208
x=13
