Answer:
Step-by-step explanation:
To obtain the strongest mix :
Maria:
2 cups of concentrate ; 5 cups of water
Ratio = 2/5 = 0.4 concentrate per 1 cup of water
Laurie:
3 cups of concentrate ; 7 cups of water
Ratio = 3/7 = 0.4285714 concentrate per 1 cup of water
0.4285714 > 0.4
Hence, Laurie's mix is the strongest as it has higher concentrate per cup of water.
Area of the rectangle y = (x+4)(-x+64)= -x²-4x+64x+256=-x² + 60x +256
y= -x² + 60x +256
Check the picture below.
so, notice, the prism is really just 6 rectangles stacked up to each other at the edges. So if we just get the area of each rectangle and sum them up, that's the surface area of the prism.
left and right, two 6x5 rectangles
top and bottom, two 17x5 rectangles
front and back, two 17x6 rectangles
