System A has ONE real solution
System B has NO real solutions
System C has ONE real solution
70 cm
ex:
100 cm in a meter
so you’d do 100-30 cm
and that equals 70 centimeters
Answer:
5.4 m
Step-by-step explanation:
The Pythagorean theorem tells you the relationship between the various lengths is ...
cd² = ac² +ad²
cd² = (2.4 m)² + (1.8 m)² = 9.00 m²
cd = √(9.00 m²) = 3.0 m
Since cd = cb and ab = ac+cb, we have ...
ab = 2.4 m + 3.0 m = 5.4 m

You may recognize this as a 3-4-5 right triangle with a scale factor of 0.6. We are asked for the sum of the lengths of the "4" and "5" legs, which is ...
0.6·(4+5) = 5.4
First, we separate all instances of t by subtracting J from both sides:
F = J + Jrt
F - J = Jrt
Then, we separate the t by dividing both sides by Jr:
Therefore, t is equal to (F - J) ÷ Jr
Simply use the formula they give you. For question 6, 4 is the radius. So the area of the circle is 4pi. Now for seven you do the same thing, but they gave you the diameter instead and it’s a half circle. So try that one on your own. Let me know if you get stuck
