Answer:
length=11 width=10
Step-by-step explanation:
Create two equations with length(l) and breath(w) as our unknowns
2l+2w=42
2l=42-2w
2l/2=(42-2w)/2
l=21-w(equation 1)
lxw=110
lw=110
Substitute equation one into equation two
(21-w)w=110
21w-w²=110
Write your equations in standard quadratic form
0=w²-21w+110
solve this as a quadriatic tri nominal
0=(w-10)(w-11)
0=w-10. or 0=w-11
10=W. 11=L
I would pick B because there is no screenshot(s) of the Model. :)
Answer:
(x,y) is in the Quadrant II.
Step-by-step explanation:
The Quadrant II contains the x-values that are less than 0 (negative x-values), while the y-values are greater than 0 (positive y-values). Therefore, if x < 0 and y > 0, then point (x, y) must be somewhere in Quadrant II of the Cartesian Plane.
