1.25/20=1x
1.25x=20
x=20/1.25=16
1 inch=16 feet
Yintercepts are where x=0
set to zero to solve
0^2+4y^2=16
4y^2=16
divide 4
y^2=4
sqrt both sides
y=+/-2
xintercept is where y=0
x^2+4(0)^2=16
x^2+0=16
x^2=16
sdqrtboth sides
x=+/-4
yintercepts are (0,2) and (0,-2)
xintercepts are (4,0) and (-4,0)
Answer: The first one is 144 . The second one is C.
Step-by-step explanation:
None of those are correct 630
2X+8=x-6
2x-x=-6-8
X=-6-8
X=-14
