Answer:
D
Step-by-step explanation:
Assuming the figure PQRS is a parallelogram, then opposite sides are congruent, that is
PQ = RS ← substitute in values
6x + 2 = 12 + x ( subtract x from both sides )
5x + 2 = 12 ( subtract 2 from both sides )
5x = 10 ( divide both sides by 5 )
x = 2 → D
Answer:
36°, 63°, 81°
Step-by-step explanation:
Let 4x = measure of angle 1
7x = measure of angle 2
9x = measure of angle 3
The sum of the measures of the angles of a triangle = 180
So 4x + 7x + 9x = 180
20x = 180
x = 9
4x = 36 = measure of angle 1
7x = 63 = measure of angle 2
9x = 81 = measure of angle 3
Check: 36 + 63 + 81 = 180
Answer:
You can’t solve but you can simplify to
3x^3-10x+1
Step-by-step explanation:
X = 15
Explanation:
9x = -135
Divide by 9 on both sides
X = -15
It is -15 since 135 is negative
