3x + 4 = x+ 8 > 3x - x = 2x > 2x + 4 = 8 > 8 - 4 = 4 > 2x / 2 crosses out > 4 / 2 = 2 > x=2
2y + 5 = y + 7 > 2y - y = y > y+ 5 = 7 > 7-5= 2 > y=2
the perimeter of the kite is 4

Answer:
Mean:(137.2)
Median:(139.5)
Step-by-step explanation:
Mean = (125+136+150+119+143) divide by six(6)
= 823/6 = approx 137.2
Median = for the median, you will arrange the numbers in other. from smaller to the bigger number.
119,125,136,143,150, 150. so 136 & 143 is the middle number.
so you will add the middle number and divide by 2.
that is 136+143/2 = 139.5.
I think it is the first one! When you plug in -7 as ^an, it follows the sequence #1.
Example: a1 = 7 an = 2 + an
you would do this:
first term = 7, second = 7+2 = 9, third = 9+2 = 11, ..........
Get it?
