Answer:
6+(2x+4)=1/2-(3+x) okay I hope this is it.
Good luck on this.
Answer: 9600cm
Step-by-step explanation: 120
*80
9600
Okay so here I go ima bout to explain it
Answer: I can help you to solve by graphing the second one, the 2 answers are 1. Slope: 1/3, x-intercept: (–6, 0), and y-intercept: (0, 2). And 2. X-intercept: (–3, –2, –5/6, 0, 1) and Y-intercept: (–16, –6, –23/12, –4, –12)
Step-by-step explanation:
This is a lot of calculation.
So we know that the sum of angles for any heptagon is 900, because heptagon can be divided into five non-overlapping triangles and sum of angles of each triangle is 180.
Now you just add up all angles and simplify the equation:
900 = (6x - 8) + 120 + (7x - 64) + (5x - 4) + 135 + (3x + 31) + (4x + 15)
900 = <span>25x + 225
Now it's just regular algebra equation. You can solve for x:
675 = 25x
x = </span>27
So the value of x is 27
