The answer is true! Good luck!
Ur not dumb!!! i graphed the line for u here. i suggest watching some khan academy videos for extra practice!
1.3 is the least because ur supposed to add a zero so they can all be the same place value
Answer:
x=5
Step-by-step explanation:
Other than using the plain special aspect of a 45-45-90 triangle where the legs are x, x, and x√2, you can solve for this.
Since the two legs have equal length, they are both x. Using the pythagorean theorem:
(x^2)+(x^2)=50 (Because 5 squared is 25 and √2 squared is 2, multiplying them gives you 50).
You can add (x^2) and (x^2) because they are the same terms (x squared).
Simplifying like so gives you:
2x^2=50
Dividing by two on both sides:
x^2=25
Taking the square root of both sides:
x=5
5x^2
6x^3y
2x^3 3xy
^ means the little number above x eg x^3
