Answer:
x = 27
Step-by-step explanation:
The angle at any point on a straight line is 180 degrees.
The middle line over there is creating a right angle which is 90 degrees.
This must mean that both sides are 90 degrees.
3x+9 = 90
3x = 81
x = 27
Answer:
True
Step-by-step explanation:
Answer:
11 miles per hour and 77 miles per hour
Y = 14x is the equation you should use! Hope this helped.
11. Area as product = 7( d + 4 )
Area as sum = 7d + 28
12. Area as product = y( y + 3 )
Area as sum = y^2 + 3y
13. In circles , 12x and 60
Area as product = 12 ( x + 5 )
Area as sum = 12x + 60
14. In circles , x and 4
Area as product = 5 ( x + 4 )
Area as sum = 5x + 20
Hope this helps :)
