Answer:
x = 0
Step-by-step explanation:
To solve this equation you would need to get x by itself on one side
1/2 (x+4)^2 - 5 = 3
1.) add 5 to both sides
1/2 (x+4)^2 = 8
2.) divide each side by 1/2
(x+4)^2 = 16
3.) find the square root of both sides
(x+4) = 4
4.) subtract 4 from both sides
x = 0
The app "Photomath" is a great way to solve problems like these and it gives a step by step explanation that might be easier to understand than mine :)
Answer:
x=144
Step-by-step explanation:
Use the polygon formula (n-2) * 180 where n is the number of points
This polygon has 8 points
(8-2)*180 = 6 * 180 = 1080
136+124+141+158+116+129+132+x=1080
x=144

Answer: Because Frank is planting <em>x </em>seeds in one and <em>4x+7</em> in the other, you need to add both of those together.
x+4x+7=<u> 5x+7</u>
