-7

Step-by-step explanation:

First, set the equation equal to one and the x's to 2

Then, solve the parts without variables

4(2)+a(2)+6(2)-5=1

8+a(2)+6(2)-5=1

8+a(2)+12-5=1

Then add like terms

8+a(2)+7=1

15+a(2)=1

Then subtract 15 from both sides

a(2)=-14

Finally, divide by two on both sides

a=-7

PLEASE HELP ASAP!!
Fed [463]

Answer: The missing statements are,

In first blank:  ∠2≅∠1

In second blank:  AC≅AC

In third blank:  Reflexive

Step-by-step explanation:

Since, The hypotenuse angle theorem states that if the hypotenuse and an acute angle of one right triangle are congruent to the hypotenuse and an acute angle of another right triangle, then the two triangles are congruent to each other.

Here, given:

∠D and ∠B are right angles.

DC ║ AB

Prove: Δ ADC ≅ Δ CBA

              Statement                                       Reason

1.∠D and ∠B are right angles       1. Given

2. ∠2 ≅ ∠1                                      2. If lines are parallel then interior angles

                                                        are equal

3. AC≅AC                                      3. Reflexive

4.Δ ADC ≅ Δ CBA                        4. Hypotenuse angle theorem
