Step-by-step explanation:
Given that,
The length of a rectangle is (0.8x - 1.6) units
Width of a rectangle is (1/4x +1 ) units.
It is assumed to find the area of a rectangle.
AREA = l b, l is length and b is width
So,
Hence, this is the required solution.
He can make 27 different salads. Since each individual option has three different salads, and there are 9 options.
Basically multiply the number of total toppings by the number of toppings in each row
Answer: 27
It's called a linear equation because the linear equation formula is y= mx+b, so they just changed the m to an a
Answer:
Yes, the area of the square would be a rational number.
Step-by-step explanation:
Area of square = 400 units² = x²
x = one side length of square
x = √400 = <u>20 units</u>
Increase each side length by 1 unit.
New side length = <u>21 units</u>
Area of new square = 21² = 441
441 is a rational number because the square root of 400 is a rational number.
√400 = 21
Therefore: If the length of each side of the square increased by one unit, the area of the square would be a rational number. The area of the square would still be a perfect square.
