A Trapezoid needs to have one pair of sides parallel.
Two of the points already plotted have the same Y value ( 3)
So the 4th dot, should have the same Y value as the first dot, which is 1.
The 4th dot should be plotted at C (5,1)
Answer: Yes it is.
Step-by-step explanation: So we are already told that segment AC is congruent to segment DC. They both have a right angle, as indicated by the angle symbol, and they share side-length BC.
According to the Hypotenuse-Leg Theorem, two right triangles that have a congruent hypotenuse and a corresponding, congruent leg are congruent triangles. AC and DC are hypotenuses and they are congruent. And BC, the shared side, is a corresponding congruent leg. And since they are both right triangles, we then know that the HL Theorem applies.
So i think here you would FOIL. so -5x^2+10x-5x+10 and then combine like terms :)
It could be the first one or the third the others are not actual measuring units
im going with the first one
Step-by-step explanation:
1. 18^2 - 10^2 = 324 - 100 = 224
Sqt(224)=14.9666
Approximate = 14.97
2. 100 - 16 = 84
Sqrt 84 = 9.1652
Approximate = 9.17
3. 225 - 49 = 176
Sqrt 176 = 13.2665
Approximate = 13.27
4. 361 - 144 = 217
Sqrt 217 = 14.7309
Approximate = 14.73
