Answer:

4 (5 + 4)

Step-by-step explanation:

1. the model show 20 + 16 which = 36

2. the first example 4 (5) + 4 which equals 20 + 4 or 24.

3. the second example 4 + 5 + 4 which equals 9 + 4 or 13.

<u><em>4. the third example 4 (5 + 4) , using order of operations, equals 4 x 9 and that equals 36.</em></u>

5. the last examples 5 (4 + 4) is 5 x 8 which is 40.

That is why the third example is correct!

Answer:

4(5+4)

Step-by-step explanation:

20 + 16 = 36

Think of PEMDAS (In this scenario you have parenthesis and addition)

4(5+4) = 20 + 16

4 (9) = 36

36 = 36

While looking at the other options:

4 (5) + 4 = 24

4 + 5 + 4=13

5 (4 + 4)= 40

Give an example for a pair of alternate interior angles, a pair of corresponding angles, and a pair of alternate exterior angles

erastovalidia [21]

Step-by-step explanation:

Consider the provided information.

Consider the figure 1:

We need to give an example of a pair of alternate interior angles, a pair of corresponding angles, and a pair of alternate exterior angles.

Alternate interior angles: If a transversal cuts two parallel line then pair of angles on the inner side of lines but on opposite sides of the transversal are know as the alternate interior angle:

For example: ∠3 and ∠6 are alternate interior angle another pair are ∠4 and ∠5.

Corresponding angles: If a transversal cuts two parallel line then the angles in same corner are called corresponding angles.

For example: ∠1 and ∠5 are corresponding angle another pair are ∠4 and ∠8.

Alternate exterior angles: If a transversal cuts two parallel line then the pair of angles on the outer side of lines but on opposite sides of the transversal are known as the alternate exterior angles.

For example: ∠1 and ∠8 are alternate exterior angle another pair are ∠2 and ∠7.
