Answer:
x= 20
Step-by-step explanation:
The three angles add to 90 degrees
x+2x+x+10 = 90
Combine like terms
4x+10 = 90
Subtract 10 from each side
4x +10-10 = 90-10
4x = 80
Divide by 4
4x/4 = 80/4
x = 20
Answer:
<h2>1).</h2>
(5a3b)(2ab)
Expand
That's
15ab( 2ab )
we have the answer as
<h3>30a²b²</h3>
<h2>2).</h2>
5y(-y² + 7y - 2)
Expand
That's
<h3>- 5y³ + 35y² - 10y</h3>
Hope this helps you
Answer: They are parallel so there is no solution.
Step-by-step explanation:
Brayden- y=5x-1 or y-5x= -1
Howard- y=5x+1 or y-5x= 1
Vincent- y=4x+5 or y-4x= 5
In summary, they are all parallel so there is no solution.
