Answer:
2.6 and 2.7
Step-by-step explanation:
The actual square root of 7 is 2.64 and that is between 2.6 and 2.7.
They give us the length of side of the square which is 3-7x.
To get an expression for the perimeter that is expressed as a product we have to multiply the expression 3-7x by four since every square has four sides. This will give us an expression of 4(3-7x). We than can use the distributive property to multiply everything inside the parenthesis by 4. This will give us an expression of 12-28x.
Find the unit rate which is 260/12 which is 21 and 2/3 now divide 286 by 21 and 2/3.
