√52-√13+√117

sqrt (4*13) - sqrt (13) + sqrt (13*9)

sqrt(4)sqrt(13) -sqrt(13)+sqrt(13)sqrt(9)

2sqrt(13) -sqrt(13)+3sqt(13)

In 15 hours bob makes 7.5 boxes. how many boxes can he make in one hour?

so 15 hours=7.5 boxes
divide both sides by 15 to get hours
1 hour=7.5/15

Triangle FGH has the following side lengths: FG = 5 ft, GH = 10 ft, HF = 12 ft Triangle PQR is similar to triangle FGH. The long

7nadin3 [17]

The first thing we must do for this case is find the scale factor.
We have then that for the larger side of both triangle, the scale factor is:
$k = \frac{RP}{HF}$
$k = \frac{7.2}{12}$
$k = 0.6$
To find the other two sides, we must apply the scale factor on each side of the triangle FGH.
We have then:

For PQ
$PQ = k * FG

PQ = 0.6 * 5

PQ = 3$

For QR
$QR = k * GH

QR = 0.6 * 10

QR = 6$

Answer:
You have that the lengths for the other two sides of triangle PQR are:
$PQ = 3

QR = 6$
