M angle 1 equals 4x + 15 + m angle 2 equals 2x + 16 what is angle 3 and what is X​
Rudik [331]

Are you talking about the angles in a triangle? Your question is not clear. I'll assume you are talking about a triangle.

Angle 1 + Angle 2 + Angle 3 = 180°

4x + 15 + 2x + 16 + x = 180°

Solve for x to find Angle 3, which in this case is the value of x.

What number must you add to complete the square x^2+2x=13
Sveta_85 [38]
You must halve the linear coefficient and then square it.   In this case:

(2/2)^2=1 so you must add 1 to both sides of the equation...

x^2+2x+1=14 now the left side is a perfect square...

(x+1)^2=14

Use the next of a rectangular prism to answer the question
Andreyy89

。☆✼★ ━━━━━━━━━━━━━━  ☾

Work out the area of the square :

6 x 6 = 36

As there are 2, multiply by 2:

36 x 2 = 72

Work out the area of the rectangle:

12 x 6 = 72

As there are 4, multiply by 4:

72 x 4 = 288

Add these values:

288 + 72 = 360

Thus, your answer is E. 360 in^2
