1. A square is a figure with four sides that have the same lenght. So, to solve this problem and calculate the area of the square, you must apply the following formula:
A=(s)(s)
A=s²
"A" is the area of the square.
"s" is the lenght of the side of the square.
2. So, the lenght of the side given in the problem is 5^2/5 inches (s=5^2/5 inches). Therefore, you only have to substitute this value into the formula A=s².
3. Then, you obtain:
A=s²
A=(5^2/5 inches)²
A=5^4/5 inches²
What is the area of the square?
The answer is: A. 5^4/5 square inches.
No because 440,000x10= 4,001,000

Step-by-step explanation:
Answer:
Step-by-step explanation:
3p + 7q= 56...(1 )
5p + 7q = 70.... (2)
Using elimination method to solve this
Substract equation 1 from 2 , this becomes:
5p - 3p + 7q-7q = 70-56
5p-3p + 0 = 15
2p = 14
Next step is to divide both 2 to get p
2p/2 = 14/2
P= 7
To get q, input p= 7 into equation 1 which is
3p +7q =56, 3(7) + 7q= 56
21+ 7q = 56, 7q= 56-21
7q= 35( divide both sides by 7)
q = 5.
Since p= 7 and q= 5, let's input values for p and q into both equation.
Equation 1: 3p + 7q= 56
3(7) + 7(5) = 56,
21 + 35 = 56.
For equation 2: 5p + 7q = 70
5(7) + 7(5) = 35 + 35 = 70.
