Answer:
x=10
50 and 40
Step-by-step explanation:
The sum of the angles of triangle is 180
90 +5x+4x = 180
Combine like terms
90 +9x =180
Subtract 90 from each side
9x = 180-90
9x = 90
x = 90/9
x = 10
The angles are 5x = 5*10 =50 and 4x = 4(10)= 40
The answer is 6m^3-9m^2t^2+3mtr^2
Answer:
False. It is an equation.
Step-by-step explanation:
The difference between an expression and an equation is that an expression represents a single value (5x + 7) whereas an equation shows that two things are equal.
(0,4)(2,-3)
slope = (-3 - 4) / (2 - 0) = -7/2
