It would take her 45 mins to grade 2 stacks or 3/4 of an hour.
Answer:
13
Step-by-step explanation:
Equation: a^2 + b^2 = c^2
5^2 + 12^2 = c^2
25 + 144 = c^2
169 = c^2 also equals (the square root of 169 = c)
The square root of 169 = 13
C = 13
3x15=45 and 17x15=255 so 45+255=300
The answer is D because of the distributive property.
You would distribute x to 19 and -23 to make it equivalent to the given equation
I hope that helps!
