<h2>d) X= - 16/9</h2>
Step-by-step explanation:
2x - 4 - 6(x + 1) = 5x + 6
2x - 4 - 6x - 6 = 5x + 6
2x - 6x - 5x = 4 + 6 + 6
-9x =16
x= -16/9

example:all students are 39
students with same grade are 16
so
Consider the expression ![5 \times 18](https://tex.z-dn.net/?f=5%20%5Ctimes%2018)
Expanding 18 as (10+8),
= ![5 \times (10+8)](https://tex.z-dn.net/?f=5%20%5Ctimes%20%2810%2B8%29)
By using distributive property, we get
= ![( 5 \times 10) + ( 5 \times 8)](https://tex.z-dn.net/?f=%28%205%20%5Ctimes%2010%29%20%2B%20%28%205%20%5Ctimes%208%29)
= 50 + 40
By adding, we get
= 90
The digit at units place is '0' and the digit at tens place is '9'.
Therefore, there are 9 tens in the final product of

A parallelogram quadrilateral in which opposite sides are parallel is called a parallelogram. The measure of ∠SRV is 48°.
<h3>What is a parallelogram?</h3>
A parallelogram quadrilateral in which opposite sides are parallel is called a parallelogram.
Thus, a parallelogram is always a quadrilateral but a quadrilateral can or cannot be a parallelogram.
The diagram for the given condition can be made as shown below. Now in ΔTVU the sum of the measure of the angles can be written as,
∠TVU + ∠VTU + ∠TUV = 180°
∠VTU = 48°
Now, since the given polygon is a parallelogram RS║TU, therefore, the measure of ∠SRV will be equal to ∠VTU because the two angles are a pair of alternate interior angles. Therefore,
∠SRV = ∠VTU = 48°
Hence, the measure of ∠SRV is 48°.
