Answer:
-7(a + 2b + 4)
Step-by-step explanation:
-7a - 14b - 28
⇒ -7(a + 2b + 4)
North Carolina was founded in 1653 by the Virginia colonists. And was also named after Charles the 9 of France but later for Charles the 1 and 2.
Triangle AEB could be proven similar to triangle DEC using the AA similarity postulate as ∠AEB ≅ ∠DEC because vertical angles are congruent; rotate ΔCED 180° around point E, then translate point D to point A to confirm ∠EAB ≅ ∠EDC.
<h3>What is AA similarity postulate?</h3>
The AA Similarity Postulate shows that two triangles are similar. If two angles in one triangle are congruent to two angles in another triangle, then the two triangles are similar.
In tis case, Triangle AEB could be proven similar to triangle DEC using the AA similarity postulate as ∠AEB ≅ ∠DEC because vertical angles are congruent; rotate ΔCED 180° around point E, then translate point D to point A to confirm ∠EAB ≅ ∠EDC.

The answer is choice A
The sample space is basically the set of all possible outcomes. Each outcome is a pair of results from drawing a card coupled with spinning a spinner.
Table A represents all of the possible outcomes properly. The card results are along the column on the left side. The spinner results along the row up at the top. Each cell is an intersection of the left and top result. For example, row1,column3 has "red,purple" to indicate you got "red" on the spinner and "purple" on the card. Each cell in table A is correctly labeled.
The other tables (B, C, D) are improperly labeled in at least one cell.
* Table B has "blue, green" in the top row" middle cell when it should be "blue, purple"
* Table C has "green, green" in the upper left corner when it should be "green, purple"
* Table D has "blue, blue" in the bottom middle cell when it should be "blue, green". Saying "blue,blue" is impossible as there isn't a blue card.
The three items mentioned above help us eliminate choices B through D.
Y=-13+3
y=-10
That is a horizontal line, it has a slope of zero.
