Answer 1

Answer:

2x² + 15x + 27

Step-by-step explanation:

(2x + 9)(x+3)

2x² + 6x + 9x+ 27

2x² + 15x + 27

Answer 2

Answer:

2x² + 15x +27

Step-by-step explanation:

Using FOIL:

⇒ 2x * x = 2x²

⇒ 2x * 3 = 6x

⇒ 9 * x = 9x

⇒ 9 * 3 = 27

It would add up to; 2x² + (6x + 9x) +27 and simplifying the parenthesis would simplify to 2x² + 15x +27.

Step-by-step explanation:

Find the value of x and find whether the angles or supplementary or complementary.

Answers

Answer:

1) x = 31

2) Both angles add up to be a supplementary angle (an angle who's sum is 180° altogether).

Step-by-step explanation:

1) Since both angles add up to be a supplementary,

→ equation 1 + equation 2 = 180

→ (3x + 25) + (2x) = 180

Solving by applying algebra will give the answer "x = 31".
