I'm assuming this means 3g+45=4g=84.
So, just move like numbers near each other. This way, you get 4g-3g=45-84, which means g= -39.
By definition, BF = 1/2 * CE;
So, BF = 1/2 * 90 = 45.
BF = 45
(Midsegment Length Theorem)
the slopes of the sides do not matter. It's the fact that AD and BC are parallel and AB and DC are NOT parallel that determines it to be a trapezoid.
Answer:
y = -1/7x - 23/7
Step-by-step explanation:
Step 1: Find slope <em>m</em>
m = (-4 + 3)/(5 + 2)
m = -1/7
y = -1/7x + b
Step 2: Find <em>b</em>
-3 = -1/7(-2) + b
-3 = 2/7 + b
b = -23/7
Step 3: Rewrite equation
y = -1/7x - 23/7
