Your answer for 15 is D or C. For 16 I’m estimating 125?
Answer:
Let the side of one square be x. Area = x*x = x²
Then the side of other square would be 2x , Area = 2x*2x = 4x²
Combined area = x² + 4x² = 5x²
This combined area = 45 cm²
you simplify
Therefore 5x² = 45 Divide both sides by 5
x² = 45/5
x² = 9 Take square root of both sides
x = √9
x = 3
Length of larger square is 2x = 2*3 = 6 cm
Length of larger square = 6cm
Step-by-step explanation:
The answer would be $5 bills
5*4 = 20 and he spent 5 you would only have 3 $5 bills.
2.4+3.06=5.46
5.46+.75=6.21
The answer is 6.21
