Al, Betty, and Carl can harvest a strawberry crop in 12 hours if the work together. If each person worked alone, Al could complete the job in 30 hours, and Carl would take twice as long as Betty. How long would it take Carl to do the job
alone? Let x be the time it take Betty to do the job alone.

96 39 cause 135 -96=39 im smart (i used a calculater)

c.

step-by-step explanation:

substitution for (0,1)

y=x^2+4x+1

1=0^2+4(x)0+1

1=0+4(x)0+1

1=4(x)0+1

1=0+1

1=1

substitution for (-3,-2)

y=x+1

-2=-3+1

-2=-2

it's undefined because anything multiplied by 0 is 0. that said, 7 days is 168 hours

wow ok so the answer is 1k or just k

because of combining like terms xd
