Maybe c or A not completely sure try looking for the one you think it is and try reading it again
A=LW
192=(13+x)((9+x)
192=117+22x+x^2 (subtract 192 from both sides)
x^2+22x-75+0 (factor)
(x+25)(x-3)=0
so x=-25 or 3
Check work
since we are adding x it can only be the positive solution so x=3 so the new dimensions are:
L=13+3=16m
W=9+3=12
check: 16*12=192 so the answer is correct hope this helped
Answer:
"Big Game's competitive footballs are the exact dimensions set down by the NCAA – approximately 10.5 to 11.5 inches in length, with a circumference of roughly 28 inches on the long side of the ball and 21 inches on the short side."

Answer:
y=1/8x+1.25
Step-by-step explanation:
Since it's perpendicular change the slope to the opposite
You have the slope so plug it into the equation y-y1=m(x-x1)
y-(1)=(1/8)(x--2)
