Answer: x=70°

Step-by-step explanation:

These are supplementary angles, meaning they add up to 180°

45+(2x-5)=180°

45+2x-5=180

40+2x=180

2x=140

x=70°

Factor the trinomial below. x2 + 14x + 48

elixir [45]

IF IT EQUALS 0
1. find two number that multiplied to 48 and adds to 14, which are 6 and 8.

2. substitute the new numbers in with x to get x^2 + 6x + 8x + 48.

3. factor out the x and the 8 to get x(x+6)+8(x+6).

4. x = -6, x = -8

IF IT DOES NOT EQUAL 0
then (x+6)*(x+8) is your answer.
