Answer:
ED = 6
Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are equal, that is
= , substitute values
= ( cross- multiply )
18 ED = 108 ( divide both sides by 18 )
ED = 6
Answer:
The answer is b
Step-by-step explanation:
0.63-0.2=0.43
Trapezoid because a trapezoid is a quaderateral with 4 sides
we need a picture of the problem.
Standard form is Ax + By = C where A and B are coefficients to x and y respectively.
We have to move things to the other side of the equal sign to get the standard form, keeping in mind that the sign changes after it crosses over
Y = 1x + 3
We move the y to the right side
1X + 3 - Y = 0
Then we move the constant over
1X - Y = -3
The standard form of 1x + 3 = y is 1x - y = -3
