<h3><u>4(2x^2 + 3x + 12)</u></h3>

We can factor a 4 out of this expression.

4(2x^2 + 3x + 12)

Now that the expression is simplified, we can see if splitting the middle term is possible.

<em><u>Display factors of 24.</u></em>

1 * 24

-1 * - 24

2 * 12

-2 * -12

3 * 8

-3 * - 8

4 * 6

-4 * -6

All factors of 24 have been listed, and none of these digits satisfy the criteria.

Trinomial cannot be further factored.

A couch and coffee table cost a total of $1017 . The cost of the couch is two times the cost of the coffee table. Find the cost
Solnce55 [7]

Answer:

The couch costs $678 and $339 for the coffee.

Step-by-step explanation:

In total you spent $1017 and it was used in 3 portions, 2 for the couch, and 1 for the coffee. First divide it and find out how much each portion costs. In this case (1017 divided by 3) the answer will be 339. Now since you spent 2 of the 3 portions on the couch multiply one portion by 2. Then you get 678 for 2 portions, hence telling us that the couch costed, $678. With the remaining one portion of 339, you already know coffee costs $339. Please give me brainliest, I am new to answering questions. Thanks!

Fill in the missing statement and reason in the proof of the Alternate Exterior Angles
gulaghasi [49]

The addition property of equality states that if you add the same value to both sides of an equation, the sides of the equation stay equal

∠EGB  and ∠AGF are congruent by <u>addition property</u>

Reason:

AB is parallel to CD;    Given

Points E, G, H, and F are collinear;    Given

The measure of ∠EGF = 180° by angles on a straight line

∠AGF and ∠AGE are adjacent angles, therefore, ∠AGF + ∠AGE = ∠EGF

  • ∴ ∠AGF + ∠AGE = 180° by transitive property

∠CHE and ∠AGF are same side interior angles

  • ∴ ∠CHE + ∠AGF = 180°

∠AGF + ∠AGE = ∠CHE + ∠AGF

Therefore, the measure of ∠AGE is equal to the measure of ∠CHE by <u>addition property of </u><u>equality</u>

  • ∠EGB + ∠AGE = ∠AGF + ∠AGE by linear pair angles

Therefore;

∠EGB  and ∠AGF are congruent by the<u> addition property</u> of equality
