Answer:
c. 441ft^2
Step-by-step explanation:
Area is height times length and since it's a square, safe to say that the sides are equal in length. So square root both of the given areas of the 2 square:
= 29
= 20
Now u have side b and c of the triangle, it's a right triangle so use the Pythagorean theorem a^2 + b^2 = c^2
a^2 + b^2 = c^2
a^2 + 20^2 = 29^2
a^2 + 400 = 841
subtract 4 from both sides
a^2 = 441
square root both sides

a = 21
Now the side a of the triangle is also a side of the small square therefore
21^2 = 441
No it is not a prime number
Part e because I did it and got it right on the test txt me if u need help
B...because there is no y intercept because of the 0,0 then you just turn the other one into a fraction and because the 1 is negitive the fraction is negitive
