Answer:
Step-by-step explanation:
number of side = n =7
Sum of all the angles of given polygon = (n -2)*180 = 5 *180 = 900
x + 140 +133 +145 + 117 + 119 + 125 = 900
x + 779 = 900
x = 900 - 779
x = 121
Answer:
1/-21
Step-by-step explanation:
Step 1: Simplify both sides of the equation.

=6x
Step 2: Subtract 6x from both sides.

=0
Step 3: Add 1/12 to both sides.

Answer: The answer is A : 6x^2+24x+24
Step-by-step explanation:
(2x+4)(3x+6)
multiple the two equations together
2x*3x=6x^2
2x*6=12x
4*3x=12x
4*6=24
combine like terms
6x^2+12x+12x+24
6x^2+24x+24
Answer:
Step-by-step explanation:
<h2>4/x=2/10</h2>
cross multiplication:
4*10=2*x
40=2x
x=40/2=20
<h2>w/2 = 4.5/6.8</h2>
6.8w=2(4.5)
6.8w=9
w=9/6.8=1.32352941
Answer:
rise/run= -20/5= -4/1=-4 slope
or you sound use the slope formula (y2-y1)/(x2-x1)
(-9-11)/(1+4)
-20/5
-4
