w x L = 36
w = L- 5
L x ( L-5 ) = 36
L^2 -5L -36 =0
<span>Use the quadratic formula
L= - b + radical b^2 - 4 (a)(c) divided 2.a
L= 5 + 13 / 2 = 18 /2 =9</span>
The discriminant is the part of the quadratic formula underneath the square root symbol: b²-4ac. The discriminant tells us whether there are two solutions, one solution, or no solutions.
63,219 is overall the lower value, but has the greater hundreds and ones place.
Hope this helps!
His is:-
250 - 2/5 *250 - 3/10 * 250
= 250 - 100 - 75
= 250 - 175
= 75 answer
