A person wishes to build a rectangular fence that will enclose an area of 317 square feet. The width of the fence is to be 3 feet less than twice its length. Set up and solve an algebraic equation to find the dimensions of the fence to the nearest tenth of a foot.

The system of equations graphed below has how many solutions?

1- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis.2- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in the first question?

Evaluate the expression for the given value of the variable. ∣-4b-8∣+∣-1-b^2 ∣+2b^3 ; b=-2
