Answer:
134 sneakers and 66 sandals
Step-by-step explanation:
Sneakers= x, sandals= y
Profit rate:
- sneakers: (10-2)/8= 25%
- sandals: (17-14)/14= 21.4%
Sneakers are more profitable, so it should be maximized.
Cost:
8x+14y≤2000
x+y≤200
if we assume the maximum of 200 shoes stocked, then:
x= 200-y
8(200-y)+14y ≤ 2000
1600 - 8y +14y ≤ 2000
6y≤400
y≤66 and x=134 is the best option
Square root each side
x-5=positive/negative 9
x=14, and -4
Answer is D (3x^6+7x^3-2x^2-2)
When distributing exponents in this case you want to multiply them
Answer:
![2x^2y[x^{2}y^{2}-6xy-4]](https://tex.z-dn.net/?f=2x%5E2y%5Bx%5E%7B2%7Dy%5E%7B2%7D-6xy-4%5D)
Step-by-step explanation:
we have
![2x^{4}y^{3}-12x^3y^2-8x^2y](https://tex.z-dn.net/?f=2x%5E%7B4%7Dy%5E%7B3%7D-12x%5E3y%5E2-8x%5E2y)
Factor ![2x^2y](https://tex.z-dn.net/?f=2x%5E2y)
so
![2x^2y[x^{2}y^{2}-6xy-4]](https://tex.z-dn.net/?f=2x%5E2y%5Bx%5E%7B2%7Dy%5E%7B2%7D-6xy-4%5D)
