First, choose variables to represent the length and width of this rectangle. Why not use L and W? Then the area is L*W=84 sq. in., and this equation could be solved for either L or W. If for L, then L=84/W.
The Perimeter of the rectangle is P = 2L + 2W. Substitute the above expression for L into this expression for P. Doing so eliminates L from your equation. Now consider graphing your equation for P(W). Does your graph show a minimum value? If so, at which W value?
Answer: 4 buffalos and 20 chickens (i think)
Step-by-step explanation:
2x+4y= 8
Ducks have 2 legs and buffalos have 4.
x= ducks y=buffalos
2(24-y)+4y=24
48-2y+4y=40
2y=8
y=4
4 buffalos
x+y=24
x=24-y
x=24-4
x=20
20 ducks
Answer: see attachment
<u>Step-by-step explanation:</u>
The standard form of a linear equation is: Ax + By = C
where A, B, and C are INTEGERS.
The 1st, 3rd, & 4th equations are in the form Ax + By = C
The 2nd, 5th, & 6th equations are NOT in standard form.
Answer:
$73,564,723.80
Step-by-step explanation:
"x is the number of years after the expansion in 2005"
This year is 2021.
2021 - 2005 = 16
x = 16



Answer: $73,564,723.80
