Answer: 8,100 cm^2
Step-by-step explanation: Area = S^2 so each side is sqrt(900) = 30cm
A square 3 times bigger has sides 30cm*3 = 90cm. The area for that square is 90^2 = 8,100 cm^2
The answer is:
-20a+24b-40c+12
Answer:
he got 36 eggs there are 12 in 1 dozen if that is the question you asked
It's 50 because 3 is half of 6
a^2 - b^2 = (a + b)(a - b)
so
x^2 - 25
= x^2 - 5^2
= (x + 5)(x - 5)
Answer is B. (x + 5)(x - 5)
