Answer:
x = 18
Step-by-step explanation:
Given:
Finding x for which 3b = 5a:
- 3(4x - 7) = 5(2x + 3)
- 12x - 21 = 10x + 15
- 12x - 10x = 15 + 21
- 2x = 36
- x = 36/2
- x = 18

Answer: 
Step-by-step explanation:
You know that the triangle ABC and the triangle DEF are similar.
Therefore, if the lenght of AC is 12 centimeters and the lenght of DF is 10 centimeters, then you can find the ratio as following:

Then, the calculte the length of EF, you must multiply the lenght BC of the triangle ABC by the ratio obtained above.
Therefore, the lenght EF is the following:

A trapezoid<span> is a quadrilateral with one pair of parallel sides, and the </span>formula for<span> the area of a </span>trapezoid<span> is 1/2 times (base 1 + base 2) times height</span>
Answer with explanation:
The coordinates of four points of Quadrilateral ABCD are
A(4, 5), B(–7, –10), C(–4, –9), D(7, 6)

Slope between two points is given by

As slope of opposite sides are equal and length of Opposite sides are equal.So,the given Quadrilateral is a Parallelogram.
Option A
Yes; The opposite sides are congruent and have the same slope.
