Answer:
sorry i just need to ask question
Step-by-step explanation:
X² + 14x + 49 = 0
(x + 7) (x + 7) = 0
x = -7
The cube has the greatest surface area.
Answer:
y = 2x+6
Step-by-step explanation:
y-4=2(x+1)
Distribute
y-4 =2x +2
Add 2 to each side
y-4+4 = 2x+2+4
y = 2x+6
This is in slope intercept form
y = mx+b where m is the slope and b is the y intercept
For this case we can define the following variables:
x: shirt
y: jeans
We write the following system of equations:
12x + 28y = 3900
8.4x + 35y = 3885
We solve the system of equations:
x = 150
y = 75
Note: see attached image for the solution of the system:
