Answer:

x = -1 and x = 4

Step-by-step explanation:

Firstly solve the quadratic expression of

2x^2-6x-8 = 0....it gives you the two brackets of.....(2x-8)(x+1)=0

then...you equate the two brackets to 0.separately

2x-8 = 0....which gives you...x = 4...as the first solution..then..;

x+1 = 0....which gives you...x = -1...as the second solution

Answer:

19.17 feet of lace will be leftover.

Step-by-step explanation:

Given:

Kaitlyn is making a quilt she purchased a 46 feet long piece of lace to sew around the edges of the quilt she needs 322 inches of lace for the quilt.

Now, to find the feet of lace will be leftover.

Total feet of lace = 46.

Kaitlyn needs lace for the quilt = 322 inches.

So, by using conversion factor we change inches into feet:

12 inches = 1 foot.

322 inches = $\frac{322}{12} =26.83\ feet.$

Feet of lace she need for the quilt = 26.83.

Now, to get the feet of leftover lace:

Total feet of lace - feet of lace she need for the quilt

$=46-26.83$

$=19.17\ feet.$

Therefore, 19.17 feet of lace will be leftover.

The angles are equal (alternate angles in parallel lines)
X + 86 = 80
X = 80 - 86 = -6

Serhud [2]

Answer: 6 1/8

Step-by-step explanation:

1/8 x 2 = 1/8 x 2/1 = 2/8 = 1/4

1/4 x 3 = 1/4 x 3/1 = 3/4

3/8 x 4 = 3/8 x 4/1 = 12/8 = 1 4/8 = 1 1/2

1/2 x 3 = 1/2 x 3/1 = 3/2 = 1 1/2

5/8 x 1 = 5/8 x 1/1 = 5/8

3/4 x 2 = 3/4 x 2/1 = 6/4 = 1 2/4 = 1 1/2

Start with the big number first.

1 1/2 = 1 4/8

5/8 = 5/8

3/4 = 6/8

1/4 = 2/8

Add them all up.

1 4/8 + 1 4/8 = 2 8/8 = 3

3 + 1 4/8 = 4 4/8

4 4/8 + 5/8 = 4 9/8 = 5 1/8

5 1/8 + 6/8 = 5 7/8

5 7/8 + 2/8 = 5 9/8 = 6 1/8
