Vera_Pavlovna [14]3 years ago
4 0

Answer:

144º

Step-by-step explanation:

In a octagon there are 8 total sides. And the angles added up all together should equal 1080º.

136 + 132 + 129 + 116 + 158 + 141 + 124 = 936

1080 - 936 = 144

x = 144º

2(4w-1)=-10(w-3)+4 help
solniwko [45]

Answer:

w = 12

Step-by-step explanation:

2(4w-1)=-10(w-3)+4

2*4w + 2*-1 = (10*w + 10*-3) + 4

8w - 2 = 10w - 30 + 4

8w - 2 = 10w - 26

26 - 2 = 10w - 8w

24 = 2w

w = 24/2

w = 12

Check:

2((4*12)-1) = 10(12-3) + 4

2(48-1) = 10(9) + 4

2*47 = 90 + 4 = 94

Identify the value of a if
Serga [27]

Answer:

a=1/3

Step-by-step explanation:

from the point on the graph

x=4 and y=8

substitute them into the equation:

y=a(x-2) (2x+4)

you will get

8=a(4-2) (2(4)+4)

8=a(2) (8+4)

8=a(2) (12)

8=2a×12

8=24a

divide both sides by 24

8/24=24a/24

1/3=a or a=1/3
