Step-by-step explanation:
There's a calculated explanation below. I hope this helps!
The Pythagorean theorem can be used to find the length of the diagonal (d) of a square.
d² = (3√2)² + (3√2)² = 18 + 18 = 36
d = √36 = 6
The measure of the diagonal is 6.
7. X2=25
X=5, x=—5
8. (X—3)2=49
X=10, x=—4
9. X2+3x—28.
X=4, x=—7.
10. 5x2–8=3x.
X=8/5, x=—1
