HELP!! -- The model for the glass building below has a scale factor of 2 inches for every 9 yards in actual length. The ratio of the surface area is . If the surface area of the windows of the model is 100 square inches, the surface area of the windows of the building is square yards. Blank #1: A. 2 inches squared: 9 yards squared. B. 4 inches squared: 81 yards squared.

Blank #2: A. 2,025 B. 2 C. 4,250 D. 450

maximum area = xy = (16)(32) = 512 ft2

to maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.'

hello :

by applying the distributive property :

6 × 4.3 = 6 × ( 4 + 0.3 )

            =   (6 ×   4) + (6 ×   0.3)

            = 24 + 1.8

6 × 4.3 = 25.8

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.

for me what is finding a good play list and going out because i can not lay down and relax so i usually go to a coffee shop. i also use the gum trick and this actually works. another advice is highlighting subjects it really does me remember certain things
