It is really simple 

consider a polynomial 

4x^2-12x

now we can see that we have 4x as a common term hence takin out 4x common

4x^2-12x = 4x(x-3)

so its factors are 4x and x-3

canoes built in jan - 7

canoes built in feb - 7*2 =14

canoes built in mar - 14*2 =28

canoes built in april - 28*2 = 56

canoes built in may - 56 *2 = 112

total canoes built - 7+14+28+56+112 =  217

hence the answer is 217

I guess you are missing something ....

The integers R and K are randomly selected, where $-3 < r < 6$ and $1 < k < 8$. What is the probability that the division R/K is an integer value? Express your answer as a common fraction.

thank you melody it is correct

thnx for the help the answer is correct .

can you ecplain that modulo part

its may be pretty simple

we can see a right angled triangle.... so apply pythagoras theorem

p² + b² = H^{2So we will get the height 2root97 we know area of trapezim = heigt*(sum of parallel sides)  /2}

^{that turn out to be 2root97 * (15 + 20)/2}

^{which is 690/2 = 345 approx}

^{leave a like}

you can use the second equation of motion s= ut+1/2at^2

here consider that the ball was at rest before kicking . and came to rest after comming to ground

then v=u=0m/s

and a=10m/s^2  (9.8) BECAUSE IT IS UNDER THE INFLUENCE OF GRAVITY.

this is only true if the ball is kicked vertically upward .

but if the ball was in a projectile motion i.e. in a 2D motion then apply the formula

H =v02sin2 θ/2g

H = maximum height (m)

v0 = initial velocity (m/s)

g = acceleration due to gravity (9.80 m/s2)

θ = angle of the initial velocity from the horizontal plane (radians or degrees).
