Answer:
o
Step-by-step explanation:
if x = 0 ,y =10
4×0+10
=10
if x = 1, y = 6
=4×1 + 6
=4 +6
=10
if x = 2, y = 2
=4×2 +2
=8 + 2
=10
u can substitute any value for x and y ...i have only used positive values here
Answer:
Step-by-step explanation:
P = 480
P = 2 length + 2 width
but we also know that
2width = length
so plug that into the length
P = 2(2width) + 2 width
480 = 4 width + 2 width
480 = 6 width
80 = width
160= length
see?
