Answer: rx-sx= -2x^2
rx+sx=4x^2+8x
(r)(s)=3x^2+16x+16
Step-by-step explanation: Hopefully this helps! :)
Area = W * L55 = 5 * L55/5 = L11 = L
Note "L" is the length.
Answer:
A(x) = -2X² + 600X
Step-by-step explanation:
Area = X · Y
Perimeter = 2X + Y = 600
Y = 600 - 2X
A(x) = X · (600 - 2X) = 600X - 2X²
A(x) = -2X² + 600X
if you want to maximize area:
A'(x) = -4X + 600 = 0
600 = 4X
X = 150
Y = 600 - (2 · 150) = 600 - 300 = 300
Area = 150 · 300 = 45,000 ft²
I'm no math wizard but I think you would solve like normal math problem. Hope it helps❤️
I feel like #19 is cut off...
20. 72000000 = 7.2 x 10^7
if you do 72000000.0 and move the decimal to the left until the number is less than 10, it'll be 7 spaces.
