The equation for 1 trapezoid is 1/2h(b1 + b2) To find two, you can just cancel out the 1/2 to get h(b1 + b2).8 times (14+ 24) is 38. So 8 times 38 is 304 units^2.
Answer:
Step-by-step explanation:
Given
Required
The third side
To do this, we make use of the triangle inequality theorem which implies that:
Where
So, we have:
Solve all inequalities
Ignore negative inequalities.
So, we have:
and
Combine
<em>The above implies that the third length is between 5 and 19 (inclusive)</em>
Answer:
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a direct variation if it can be expressed in the form or
In this problem we have
y=18 when x=2
Find the value of the constant of proportionality k
---->
therefore
The equation is equal to
Answer:
Step-by-step explanation:
1/4 inch to 3/8 ft = x inches to 1 ft
(1/4) / (3/8) = x / 1
cross multiply because this is a proportion
3/8x = 1/4
x = 1/4 * 8/3
x = 8/12 which reduces to 2/3 inches <==
