Answer:
237.3
Step-by-step explanation:
the answer is 712/3=237
Squaring both sides we get,x^2-2x+1=6x+10,,,x^2-8x-9=0.factoring by middle term breaking, x^2--9x+x-9=0,(x+1)(x-9)=0,x=-1,9
Answer:
6/81
Step-by-step explanation:
$80 times 0.25 equals 20
80 minus 20 equals 60 bucks
A= Area
l= length
w= width
l= w-3cm
A= l*w
A= 53cm²
53= l*w
(plug in value of length)
53= (w-3)(w)
0=w²-3w+53
Use the quadratic formula:
(in the pictures attached)
w= about 9cml=9-3=
6cmAny questions?
