Given the perimeter of a rectangle and either the length or width, find the unknown measurement using the appropriate formula.

Yuki888 [10]

$p = 2l + 2w$
P=Perimeter
L=Length
W=Width

Hints given are P= 76, L=20 so 2L=40

76=40+2w
76-40=2w
36=2w
18=w

Find all values of k so that the trinomial x^2 + kx - 35 can be factored using integers

Korvikt [17]

$(x-r_1)(x-r_2)=x^2-(r_1+r_2)x+r_1r_2$

So the trinomial $x^2+kx-35$ can be factored as long as

$\begin{cases}r_1+r_2=-k\\r_1r_2=-35\end{cases}$

has integer solutions for $r_1,r_2$ . Clearly, both have to be factors of -35, which leaves only a handful of cases:

$(r_1,r_2)=(1,-35)\implies r_1+r_2=-34$
$(r_1,r_2)=(-1,35)\implies r_1+r_2=34$
$(r_1,r_2)=(5,-7)\implies r_1+r_2=-2$
$(r_1,r_2)=(-5,7)\implies r_1+r_2=2$

So the possible values of $k$ are $\pm34$ and $\pm2$ .

a ball is dropped from a height of 784ft. It's height h, in feet, after t seconds is given by h(t) =784-16tsquared. After how lo

Nitella [24]

h(t) = -16t2 + 64

Time to reach ground:

h(t) = 0

-16t2 + 64 = 0

Solve for t, keeping only the positive solution.

Time to fall 36 ft:

Since it is dropped from 64 ft, its height after falling 36 feet is 64-36=28 ft.

28 = -16t2 + 64

-16t2 + 36 = 0
