Answer:
A trapezoid was broken into a rectangle and a triangle. What is the length, b, of the base of the triangle?
The correct answer to the question is 4 cm
Step-by-step explanation:
The trapezoid with sides 10 cm, 12 cm, and 14 cm to look for the length of the base of the triangle formed by braking the trapezoid into rectangle and a triangle
Please see attached diagram
The length of the trapezoid = 14 cm
The opposite parallel side = 10 cm
When the trapezoid is broken along the second end of the opposite parallel side to form a rectangle with length 10 cm by 12 cm as shown below, the base b of the triangle will then have a length of 4 cm so that
Length of base of triangle + length of base of rectangle = original length of base of trapezoid
The answer is 4 cm

Answer:
Step-by-step explanation:
t + u = 11 ----------- (1 )
10t + u = 10u + t - 9
10t + u - 10u - t = -9
10t - t + u - 10u = - 9
Combine like terms
9t - 9u = -9
Divide the entire equation by 9
t - u = -1 --------------(2)
Add equation (1) & (2) and so, u will be eliminated and we can find the value of t
(1) t + u = 11
(2) <u>t - u = -1</u>
2t = 10
t = 10/2
t = 5
Plugin t = 5 in equation (1)
5 + u = 11
u = 11 - 5
u = 6
The original number is 56
