X = 14
1/2 of 14 = 7
7 + 13 = 20
65%
There are only 7 numbers that don't fit this criteria. Therefore, there are 13 that do. 13/20 = .65*100 = 65%
In the case above, the side-side-angle (SSA) is no valid means for establishing triangle congruence.
<h3>What is the
triangle congruence about?</h3>
Using the image attached:
m angle A = M angle A
AB = A¹B¹
BC = B¹C¹
Looking at the image of both angles you will see that both are not congruence because Two triangles can be regarded as congruent if and when all its three corresponding angles or sides are said to be equal and all the three corresponding angles are also said to have equal measure.

Answer:
10x^2-4x
Step-by-step explanation:
We will have to open the bracket first
So let's solve
2x(5x-2)
10x^2-4x
Since we are not asked to solve further so we will have to leave he final answer as 10x^2-4x
But in the case where a certain value is given to substitute for x we will have to solve further
