You have to find the Greatest common factor (GCF) to factor this binomial. First you should see what goes into both 8 and 12... the greatest number that goes into both is: 4... so basically you would have to divide 4 into both 8 and 12. You will get 2 and 6. Once you finish getting the GCF of both numbers, then you would put both the number in parenthesis like this (2+6). But there’s still a variable, which is x. So you would put that in the parenthesis with its coefficient. It will look like, (2x+6). Once you get this, get your GCF of 4 and put it on the outside of your parenthesis. It should look like, 4(2x+6)

Your answer should be —> 4(2x+6)

PLEASE HELP I WILL MARK THE BRAINLIEST
-BARSIC- [3]

Given: lines l and m are parallel, and line t is a transversal.

angle pair result/justification

1 and 2 are equal (vertical angles)

6 and 8 are equal (corresponding angles)

1 and 4 are equal (alternate exterior angles)

4 and 8 are supplementary angles (i.e. add up to 180 degrees, a straight angle)

Note:

alternate angles are on opposite sides of the transversal, and each attached to a different (parallel) line.

If they are both enclosed by the parallel lines, they are alternate interior angles (examples: angles 2 and 3, 6 and 7)

If they are both outside of the two parallel lines, they are alternate exterior angles (examples: angles 1 and 4, 5 and 8)

The perimeter of a rectangular piece of plastic is 30 millimeters. The area is 54 square millimeters. What are the dimensions of
Delvig [45]

Answer:

6 mm and 9 mm are the dimensions of the piece of plastic.

Step-by-step explanation:

Keep in mind the formulas for the area and perimeter of a rectangle:

A = lw

P = 2 (l + w)

List the factors of 54:

1, 2, 3, 6, 9, 18, 27, 54

POSSIBLE DIMENSIONS of the piece of plastic:

1 mm and 54 mm:

Area - 54 mm^2

Perimeter - 110 mm

2 mm and 27 mm

Area - 54 mm^2

Perimeter - 58 mm

3 mm and 18 mm

Area - 54 mm^2

Perimeter - 42 mm

6 mm and 9 mm

Area - 54 mm^2

Perimeter - 30 mm

The rectangular piece of plastic with the dimensions 6mm and 9 mm corresponds with the area and perimeter of the piece of plastic mentioned. So these are the correct dimensions.

Hope this helps!

Equation M: y = 3x + 4
solmaris [256]
Y = 3x + 4
y = 3x + 7

3x + 4 = 3x + 7
3x - 3x = 7 - 4
0 = 3.....incorrect....this system has no solutions because ur lines are parallel and they never cross.

or look at it this way..
y = 3x + 4
y = 3x + 7

both have slopes of 3...but the y intercepts are different......when this happens, it means the lines are parallel with no solution
