astraxan [27]

Answer:

6 (y + 8) (y - 1)

Step-by-step explanation:

Factor the following:

6 y^2 + 42 y - 48

Factor 6 out of 6 y^2 + 42 y - 48:

6 (y^2 + 7 y - 8)

The factors of -8 that sum to 7 are 8 and -1. So, y^2 + 7 y - 8 = (y + 8) (y - 1):

Answer: 6 (y + 8) (y - 1)

PS: it's really helpful to pose the question correctly 6 y^2 + 42 y - 48 NOT

6y 2 - 48 + 42y

The length of a lacrosse field is 15 yards less than twice the width, and the perimeter in 270 yards. The defensive area of the

sammy [17]

The defensive area is 510 square yards

Step-by-step explanation:

Let L be the length of the rectangle

and

W be the width

According to given statement

L = 2W-15

Perimeter = 270

$P = 2W+2L\\270 = 2W + 2(2W-15)\\270 = 2W + 4W -30\\270 +30 = 6W\\6W = 300$

Dividing both sides by 6

$\frac{6W}{6} =\frac{300}{6}\\W = 50\ yards\\\\and\\L = 2(50) -15\\= 100-15\\=85\ yards$

We have to find the area first to find the defensive area

So,

$Area = L* W\\= 85 * 50\\=4250\ square\ yards$

Defensive area = 3/25 of total area

So,

$=\frac{3}{25}*4250\\=3 *170\\=510\ square\ yards$

Hence,

The defensive area is 510 square yards
