So first we establish that opposite angles are equal, and therefore 12x-28 is equal to 5x+38
Then we establish that opposition sides are equal, and therefore 3y+3 is equal to 24
(-8,-5). If you think about it, for a rectangle, the x-coordinates must be the same in two pairs and the y-coordinates must be the same in two pairs. Since there are already 2 0's, 2 1's, you need a -8 and -5 to complete it. Hence, the last coordinate is (-8,-5)
Answer:
You multiply the length and the width to get the area.
Step-by-step explanation: For example if the length was 5 and the width was four the answer would be 20 because 5x4=20
That would be the surface area of a circle with a radius of r.
60=4πr^2
r^2=15/π
r=√(15/p) and if we use 3.14 as an approximation of π
r=√(15/3.14)
r≈2.19 units to nearest hundredth of a unit
