Answer:
first calculate the area of the rectangle which is given by L×W
take thw length of the rectangle and substract the b of the trapezium which 4.5 you find y divide it by 2 since they're two. the answer you'll get is the height of both shaded triangles . take the base of the shaded triangles and the height y then find the area. the answer you'll get multiply it by 2.
Step-by-step explanation:
11×7=77
11-4.5=6.5
6.5/2
(½×7×6.5/2)2
=22.75m²
Answer:
x+7y = -77
Step-by-step explanation:
multiply both sides by 7 to get rid of denominator
7y = -x-77
now move x term to other side
x+7y = -77
Just divided the 43,000 by 2.5% and then add the 5 years
For this case we have the following system of equations:
We multiply the second equation by -3:
Thus, we observe that the second equation is equivalent to the first, if we add both we get:
The equality is fulfilled. The lines are on top of each other.
