Step-by-step explanation:
First she needs to estimate or guess what length they may be, like say the eraser is 2 1/2 inches, she then can use a ruler on the paper to get the actual length.
Answer:
a) {3,6,9}
Step-by-step explanation:
multiples of 3=3,6,9
multiples of 2=2,4,6,8,10
b) a n b = {6}
Jacob wants to build a rectangular enclosure for his animals. One side of the pen will be against the barn,so he needs no fence on that side.
Let w be the width of the enclosure (perpendicular to the barn) and let l be the length of the enclosure (parallel to the barn).
one side of the length is not counted for perimeter because one side of length will be against the barn.
Perimeter = 400 ft
Perimeter of rectangle = L + W + W
400 = L + 2W
L = 400 - 2W
Area = L * W
Replace L by 400 - 2W
A(W) = (400 - 2W) * W

Now we find out x coordinate of vertex to find the width that maximize the area

a= -2 and b = 400

The width w would maximize the area is w = 100ft
To find maximum area we plug in 100 for W in A(W)


the maximum area is 20,000 square feet
