Answer:
8.3
Step-by-step explanation:
Use the pythagorean theorem: a2 + b2 = c2 a2 would be 24.1 and c2 would be 25.5. square them then subtract a2 from b2. then find the square root of your answer which is 8.3
Answer:
C = a² + 2ab + b²
Step-by-step explanation:
From the diagram above,
Let the dimension of the square be
A (length) = (a + b) and B (breadth) = (a + b).
Area of the square is A*B
A * B = (a + b) * (a + b)
Area = a² + ab + ab + b²
Area = a² + 2ab + b².
Therefore the expression that defines the area of the square is a² + 2ab + b².
12. since the straws are 4 inches long and she wants to cut them into 1/2 in you would get eight 1/2 pieces on that one straw but since she has two straws she has sixteen 1/2 pieces so no she does not have enough to cut twenty 1/2 pieces
Your answer should be 0.3000
