(1,-3) is the answer i believe but not 100% sure
Answer:
2) 92.2km
3) B
4) 4.8m
Step-by-step explanation:
Equation: a² + b² = c²
2)
60² + 70² = c²
3600 + 4900 = c²
8500 = c²
√8500 = c
92.2 = c
3)
12² + 4² = c²
144 + 16 = c²
160 = c²
√160 = c
12.6 = c
4)
4.5² + 1.6² = c²
20.25 + 2.56 = c²
22.81 = c²
√22.81 = c
4.8 = c
Knowing how to write two-column geometry proofs provides a solid basis for working with theorems. Practicing these strategies will help you write geometry proofs easily in no time:
Make a game plan. Try to figure out how to get from the givens to the prove conclusion with a plain English, commonsense argument before you worry about how to write the formal, two-column proof.
Look up how to do geometry proofs and the first thing that should pop up if your on google should be a site called dummies.com
The first thing to do is to work out the biggest number that goes into bother 24 and 3. As the only that goes into three- other than 1- is itself, one can assume this is the number we are looking for.
Next, divide bother numbers by 3.
24 / 3 = 8
3 / 3 = 1
You now take 3 out of the brackets, and leave 8 and 1. 24x / 3 = 8x.
3(8x + 1)
Answer:
(3x^2-5x-5)/(x^2+x) <--- answer
Step-by-step explanation:
3x/(x+1) - 5/x = (3x^2 - 5(x+1) )/[ x(x+1) ]
= (3x^2 - 5x - 5)/(x^2 + x)
