(a+b)^2 = 37
a^2 + 2ab + b^2 = 37
Substitute ab = 5 into a^2 + 2ab + b^2 = 37
a^2 + 2(5) + b^2 = 37
a^2 + b^2 + 10 = 37
a^2 + b^2 = 27
Answer
a^2 + b^2 = 27
Answer:
I believe the answer would be A
Step-by-step explanation:
Answer:
(I can't figure out number one)
2. 7 1/2 feet below sea level or -7 1/2 feet
3. It would stop on the 17th floorl
Step-by-step explanation:
2. You subtract 20 1/2 by 28 to get your answer. Flipped around, 28 - 20 1/2 is 7 1/2 so back to the right way would be -7 1/2 or 7 1/2 feet below sea level.
3. 23 + 5 = 28
28 - 14 = 14
14 + 3 = 17
So the 17th floor would be the answer.
We will find the volume by multiplying length * width * height, like this:
10 cm * 3 cm * 2 cm = 60 cm^3
For ml, when we talk about volume, we know that the 1 ml = 1 cm^2, so the answer for ml is 60ml.
Answer:
10 feet
Step-by-step explanation:
18 × 2 = 36
56 - 36 = 20
20 ÷ 2 = 10
To check work, add all lengths together. 4 sides. 18 + 18 + 10 + 10 = 56
