Note: This looks incorrect but I couldn't find what's wrong.

x=39.83

angle 1= 84.66 degrees

Step-by-step explanation:

The total sum of the exterior angles of any polygon is 360 degrees.

I see that angle 1 is congruent to angle (2x-5)

Here's our equation:

x+21+x+12+45+2x-5+53+2x-5=360

6x+121=360

6x=239

6x/6=239/6

x=39.83

angle 1 = 2x-5 = 2(39.83)-5 = 84.66 degrees

The area of a rectangle is x 2 – 3x – 28. If the length is x + 4, find the width.

Hatshy [7]

Answer:

-4 square units

Step-by-step explanation:

a = l × b

x2 - 3x - 28 = (x +4)(×)

x2 - 3x - 28 = x2 + 4x

-3x - 28 - 4x = 0

-7x - 28 = 0

-7x = 28

x = -4

Solve. -7x=x^2+12 help

Nat2105 [25]

Hey There!

The answer to your problem is $x=-3$ or $x=-4$ both answers are correct!

Step 1: Subtract x²+12 from both sides.

−7x−(x²+12)=x²+12−(x²+12)

−x²−7x−12=0

Step 2: Factor left side of equation.

$(-x-3)(x+4)=0$

Step 3: Set factors equal to 0.

$-x-3=0$ or $x+4=0$

Get your answer:

$x=-3$ or $x=-4$
