So, 21 divided by 4 = 5.25 inches each side
5 1/4 inch.... You basically dicide 21 by 4 because a square has for sides

In the Diagram Lines M And N are Parallel M < 2 = 150 degress, Find the Measure of the following angles <4=?
<6=?

Answers

The value of <4 = 150 and <6 = 150.

what are parallel lines?

The fundamental characteristics listed below make it simple to recognize parallellines.

  • Straightlines that are always the same distance apart from one another are called parallel lines.
  • No matter how far apart they are from one another, parallel lines can never intersect.

Given:

m<2 = 150

Now, from the Diagram

m<2 = m<4 (Corresponding angle)

m<4 = 150

and, m<6 = m<4 (VerticallyOpposite Angle)

m< 6 = 150

Hence, the value of <4 = 150 and <6 = 150.

<4= 150
<6=150
because the angels are parallel <4 & <2 are the exact same measurements and because 6 is perpendicular to  <4 & <2 thus making it also 150 degrees

Factor 6y 2 - 48 + 42y.

(6y + 8)(y - 6)
6(y + 8)(y - 1)
6(y - 1)(y - 7)

Answers

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

Answer:

6 (y + 8) (y - 1)
