172.9
You find it by multiplying each side of the triangle by the height (9) and adding the results together.
A(lateral) = 8 * 9.1 + 3 * 9.1 + 8 * 9.1
= 72.8 + 27.3 + 72.8
= 172.9
Answer:
xz+y-2x-5
Step-by-step equation
You can only combine like terms
Answer:
y < - 6
Step-by-step explanation:
Given
- 2y > 12
Divide both sides by - 2, reversing the symbol as a result of dividing by a negative quantity.
y < - 6
Answer:
b=74
Step-by-step explanation:
You just gotta use sum of angles in a triangle and sum of angles on a straight line.
Answer:
y = -1/3x - 5 1/3
Step-by-step explanation:
Slope Intercept =
y=mx + b
Substitute the Slope
y= -1/3x + b
Substitute x and y from the point into the equation
-6 = -1/3(2) + b
-6 = -2/3 +b
Isolate the b with the addition property of equality
-5 1/3 = b
Substitute all variables
y = -1/3x - 5 1/3
