Answer: z=1/2 or 0.5
Step-by-step explanation: 1. Subtract 19/2 to both sides. 13-19/2 is equal to 7/2 or 3.5." So then you're left with 7z=3.5
2. Divide by 7 to both sides. 3.5/7= 0.5.
3. z=0.5

Answer:
polygon B = 20 meters
Step-by-step explanation:
polygon A : polygon B
3 : 4
15 : x
first take 15 and divide by 3, this would tell us how much it went up by:
15 ÷ 3 = 5
next, take 4 and multiply it by 5:
4 x 5 = 20
this means that polygon B is 20 meters
8 + -3x-15/2x^2+×+2 should be the correct answer.
