Answer:
C- the figure has one pair of opposite sides that are marked parallel
Step-by-step explanation:
A trapezoid is a quadrilateral with one pair of parallel sides.
Since this figure has only one pair of sides marked parallel, it is a trapezoid.
For solve equation by <span>graphing, it need to come equation at the form, that it's simple to build a graph for left part of equation, and another graph for right part. The intersection of thats two graphs is the solution.

Answer:
B)3 = 5x2 – 10x
D)8 = 5(x2 – 2x + 1)
G) = (x – 1)2
Step-by-step explanation:
Given quadratic : 3 - 4x = 5x2 - 14x
We need to apply completing the square to solve the equation.
First step is to get rid 4x from left side.
We can add 4x on right side to get rid from left side.
3 = 5x^2-14x+4x
On simplifying this step, we get
3 = 5x^2-10x
Now, we need to factor out 5 from right side to get the coefficient of x^2 as 1.
We get,
3 = 5(x^2-2x)
Now, coefficient of x is -2. So, we need to add half of the square of -2.
-2/2 = -1.
And square of -1 is 1.
Therefore, adding 1 inside parenthesis and 5×1 = 5 on left side, we get
3+5 = 5(x^2 -2x+1)
8 = 5(x^2 -2x+1)
Let us find the perfect square of (x^2 -2x+1).
(x^2 -2x+1) = (x-1)^2
Therefore, we get
8 = 5(x-1)^2.
So, the above highlighted are steps in the process of completing the square.
Answer:
2960
Step-by-step explanation:
360 x 20 = 7200
212 x 20 = 4240
7200-4240 = 2960
