Answer:
cm for centimeters, km for kilometers.
If 2.5cm → 15 km, then
17.5 cm → x km
x= (15km*17.5cm)/(2.5cm)=105 km
Step-by-step explanation:
Answer:
x+3 will be factor of polynomial
Step-by-step explanation:
We have given polynomial
We have to find that is x+3 is one of factor of polynomial
For this if x+3 will factor of polynomial
Then if we put x=-3 in the polynomial then the the value of polynomial will be zero
As
So x+3 will be factor of polynomial
Answer:
3
Step-by-step explanation:
21 can be divided by 3 also 36
Answer:
it would take 40 pounds of pressure to break the board.
Step-by-step explanation:
Now we plug in the numbers of force and length
Now we multiply both sides by 2.5 to get rid of the fraction.
Now we plug in our variation constant
So we convert the length of 2.5 feet into inches. This is 18 inches. Since there are 12 inches in one foot, we have that 18 inches is equal to 18 divided by 12.
18÷12=1.5
We get that 18 inches is equal to 1.5 feet
we plug L = 1.5 into our inverse variation equation and solve for F.
This simplifies to F = 40
