Answer:
+4
Step-by-step explanation:
The numbers above are all odd number
The arithmetic progression is the addition of +4
7+4=11
11+4=15
15+4=19
8) you go up by 2 on the y-axis and over 3 on the x-axis
9) you have to go up 3 on the y-axis and over 2 on the x-axis
But you always have to go over then up
Answer:
x = 19
Step-by-step explanation:
Assuming all angle measures are in degrees, the sum of them is 180:
(3x +16) +(4x -15) +(2x +8) = 180
9x +9 = 180 . . . . collect terms
x + 1 = 20 . . . . . . divide by 9
x = 19 . . . . . . . . . .subtract 1
The value of x is 19.
A number times 1 always equals itself, so: 4×1 = 4, OR 2×2 = 4
