1. 15x+1
2. 56x^2+8x
3. 56x+8
4. 15x^2+9x
We cannot determine the area of the rectangle without knowing the measurements of its length and width. The answer is not provided in the given options.
Find the area of the rectangle. rectangle 7x + 1 by 8x
1. 15x+1
2. 56x^2+8x
3. 56x+8
4. 15x^2+9x
The formula for the area of a rectangle is A = length x width. Substituting the given values, we get:
A = (7x+1) x (8x)
A = 56x^2 + 8x
Therefore, the answer is option 2: 56x^2 + 8x.
To find the area of a rectangle, you need to know the lengths of its sides. In the given image, we can see that the length of one side is represented by the expression "15x + 1" and the length of the other side is represented by the expression "56x^2 + 8x".
To calculate the area of the rectangle, you simply multiply the lengths of the two sides together.
Therefore, the area would be:
Area = (15x + 1) * (56x^2 + 8x)
Now you can simplify the expression by multiplying the terms:
Area = 840x^3 + 120x^2 + 56x^2 + 8x
Combine the like terms:
Area = 840x^3 + 176x^2 + 8x
Therefore, the correct answer is option 2: 56x^2 + 8x.
