They both have an answer that is bigger than the numbers being added or multiplied together <span />
Answer:
I think - 11 Is a negative number that is why it is an integer number maybe whole number also
Answer:
The correct option is;
C. 52.2 × 4.4 × 2 + 47.8 × 4.4 × 2
Step-by-step explanation:
The area of the square frame is the area of the inner square subtracted from the area of the outer square
Which gives;
52.2² - 47.8² = 440
Therefore;
Option A. 52.2² - 47.8² is a correct way of finding the area of the square frame
Option B. 2 × ((52.2×2.2) + (47.8×2.2)) = 440, is a correct way of finding the area of the square frame
Option C. 52.2 × 4.4 × 2 + 47.8 × 4.4 × 2 = 880, is not a correct way of finding the area of the square frame
The error is the thickness is 2.2 not 4.4
Option D. 100×(52.2 - 47.8) = (52.2 + 47.8) × (52.2 - 47.8) = 52.2² - 47.8² = 440, is a correct way of finding the area of the square frame
A^2+b^2=c^2
4 squared and 3 squared =25
square root of 25 is 5
answer is d
Holigina, this is the solution:
Let's recall that √x = x ^(1/2)
Therefore,
√x√x = x ^(1/2 + 1/2) = x^1 (We sum the exponents of the same base)
The correct answer is C. 1
