Each side=9 bc 9 times 9 times 9=729
Answer:
50.5
Step-by-step explanation:
Sooo first we calculate edf. 11/2= 5.5, 5.5x5=27.5
And then we do the other part.9/5=4, and 4x11.5=46, and we need to cut that in half cuz it’s a triangle 46/2=23. We add up the rectangle and the triangle: 27.5+23=50.5
Answer:
± 2
Step-by-step explanation:
let the number be n , then
n² - 4 = 0 ( add 4 to both sides )
n² = 4 ( take square root of both sides )
n = ±
= ± 2
The number is - 2 or 2
