With perimeter, all you have to do is add all the lengths and widths together.
7.5 + 7.5 + 4 + 4 = 23
Answer : 23 m

Answer:
2x²-2x-24
Step-by-step explanation:
Something has roots of 4 and -3 we can write
(x-4)(x+3)
We then attach a constant, a that will ensure that it passes through the correct point
a(x-4)(x+3)
now plug in the numbers and solve for a
a(3-4)(3+3)= -12
a(-1)(6)= -12
-6a= -12
a=2
So we have
2(x-4)(x+3)
and now it's just a matter of mulitplying/simplifying things
(x-4)(x+3)= x²-x-12
2(x²-x-12)= 2x²-2x-24
The estimate to 4 x 979 is 4 x 1,000. The answer is 3,916
Answer:
1.10 quarts
Step-by-step explanation:
We are given that
Capacity of system=20 quarts=
1 gallon=4 quarts
Initially mixture contains
Antifreeze=3 quarts=
Water=17 quarts=
Water runs in to the system=1gal/min
We have to find the antifreeze in the system at the end of 5 minutes.
Concentration inflow=0
Let Concentration outflow=x
Rate of system=Concentration inflow(water inflow rate)-Concentration outflow(water outflow rate)


Taking integration on both sides






Using formula



Substitute t=5

Hence, in the end of 5 minute ,the antifreeze in the system=1.10 quarts
