let two integers be x and y
A.T.Q
x+y= -3
or, x= -3-y(i)
and xy= -18
or,(-3-y)y= -18[by(i)]
or,- -3y-y²= -18
or,-y²= -18+3
or, -y²= -15
or, y²=15
therefore y=✓15
from (i)
x= -3-✓15
y=√15
11+b-y
Hope this helps
Have a happy holidays
Answer:
32 cars
Step-by-step explanation:
we know that he can paint 12 cars in 3 weeks.
that means that he can paint 4 cars per week.
4cars x 8weeks = 32 cars in 8 weeks
Divide the speed value by 1.609,
1kilometer per hr=0.621mph
80kph=49.7097Mph
