Answer:
Perimeter: 4 * s
Area: S 2
Diagonal: s 2 \sqrt {2} 2
Area of square when diagonal is given = 1 2 × d 2 \frac {1} {2}\times d^ {2} 21 × d2

Answer:
The Earth's orbit makes a circle around the sun. At the same time the earth orbits around the sun, it also spins. In science, we cal that rotating on its axis. Since the earth orbits the sun AND rotates on its axis at the same time we experience seasons, day and night, and changing shadows throughout the day.
Let the three consecutive integers be x , x+1 ,x+2
Given, sum of three consecutive integers = -126
x +x+1+ x+2 = -126
3x +3 = -126
3x = -126 -3
3x = -129
x = -129/3
x = - 43
x +1 = -42
x +2 = -41
Answer:
12 hr. mowing lawns
28 hr. working at Mc Donalds
Step-by-step explanation:
Let t = time mowing lawns
then 40 - t = time working at McDonalds
7,5(40 - t) + 6t = 282
300 - 7.5t + 6t = 282
-1.5t = -18
t = 12 hr. mowing lawns
40 - t = 40 - 12 = 28 hr. working at Mc Donalds
