The correct factorization of this equation is (2y - 8)(x + 4).

In order to factor polynomials with 4 terms like this, you can often use a strategy called grouping. To do that, split into two different binomials.

(2xy + 8y) and (-8x - 32)

Now you can factor out the greatest common factor of each parenthesis.

2y(x + 4) and -8(x + 4)

Now in grouping, if after factoring out the greatest common factor, you can put the two things you pulled out in one parenthesis. You can multiply that by one of the matching set for the final answer.

(2y - 8)(x + 4)

Answer:

A

Step-by-step explanation:

The figure has two disjoint pairs of consecutive sides which are congruent.

Thus the figure is a Kite

Using the properties of a Kite

• The diagonals are perpendicular

• The main diagonal diagonal bisects the pair of opposite angles

Hence ∠1 = 90° ( diagonals are perpendicular )

The angle 22° is a bisected angle so the angle below is also 22°

The sum of the 3 angles in a triangle = 180°, hence

∠2 = 180° - (90 + 22)° = 180° - 112° = 68°

The solution is A

Thank you for posting your question here. Below is the solution:

ark worked 5 2/3 + 9 1/3 = 15 hours. 8 3/5 + 9 2/5 = 18 hours + 9 hours. 
<span>15 + 18 + 9 = 42 hours worked @ $6.55 per hour </span>
<span>40 hours regular pay and 2 hours overtime. </span>
<span>Over time is 1 1/2 X $6.55 = $9.83 per hour X 2 hours overtime worked = $19.65 in over time . </span>
<span>40 hours @ $6.55 = $262.00 + $19.65 = $281.65.Gross pay </span>

<span>Chris. </span>
<span>5 1/2 + 9 1/2 = 15 hours </span>
<span>8 4/5 + 5 1/5 = 14 hours </span>
<span>14 + 15 = 29 hours worked. @ $9.65 per hour = $279.85 Gross pay </span>
