L=n-2, W=4+L=n+2
A=LW, since L=n-2 and W=n+2 we have:
A=(n-2)(n+2) so it could be this expression or the expansion
A=n^2-4
Answer:
284 miles per hour
Step-by-step explanation:
1136/ 4= 284
284 is the answer
Use quadratic formula since we can't factor
for 0=ax²+bx+c

so, for
0=1x²-6x-4
a=1
b=-6
c=-4





the solutions are x=3+√13 and x=3-√13
or aprox
x≈6.61 and x≈-0.61
