Perimeter of the rectangle = length + length + width + width
P = (3x-3) + (3x-3) + (x-3) + (x-3)
P = 3x + 3x + x + x - 3 - 3 - 3 - 3
P = 8x - 12
Perimeter of the triangle = side 1 + side 2 + side 3
P = (2x-1) + (2x-1) + (2x)
P = 2x + 2x + 2x - 1 - 1
P = 6x - 2
The perimeter is equal for both shapes
6x - 2 = 8x - 12
-2 + 12 = 8x - 6x
10 = 2x
x = 10÷2
x = 5
The length of fencing needs to be bought for each shape is (use either expression of perimeter to work it out)
P = 6x - 2 = 6(5) - 2 = 30 - 2 = 28 feet
Answer:
10
Step-by-step explanation:
Plug in 2 for x.
f(2) = 3·(2)²-2
=3·4-2
=12-2
=10
Answer:
Find the deal in which you can get the most bagels for the cheapest price.
Step-by-step explanation:
Well, for starters you would look at all of the bagel deals, and find the cheapest few. Most likely in stores, you can find deals that are cheap when the bagels are in bulk. For example, if the store is selling 6 bagels for $4, then to get 11 bagels, you would pay 8 dollars (i do not know if the solution should count tax or not), but if the store was selling 15 bagels for 7 dollars (maybe a different brand, or it is on sale), (also since there is alot , it may be cheaper). You should consider brand, location, and quantity.
