A piece of sheet metal is 2.7 times as long as it is wide. It is to be made into a box with an open top by cutting 3-inch squares from each corner and folding up the sides. Answer the following questions.
1)Represent the length of the original piece of sheet metal in terms of x.
The length is 2.7x
2)x has restrictions. Which of the following are the restrictions for x?
x>6
3)Which function V represents the volume of the box in terms of x?
V=3(x-6)(2.7x-6)
4)The volume of the box must be between 600 and 800 cubic inches. Between which two values must x be in order to produce this range of volumes?

Question 1192514: Can i please get help..
A surveyor knows that a lot has the shape of an isosceles triangle. If the vertex angle measures 80° and each equal side is 160 feet long, what measure (in degrees) does each of the base angles have?
we have an ISOSCELES TRIANGLE, but we are given the VERTEX ANGLE , which gives us the equation: BASE ANGLE + VERTEX ANGLE+ SECOND BASE ANGLE = 180. If you make both base angles a variable and the vertex angle 80 , you will find the value of 'x' ,which is a base angle.

Question 1192513: Can i get help with a question please...
Because of construction along the road from A to B, Alinna drives 8 miles from A to C and then 15 miles from C to B.
How much farther (in miles) did Alinna travel by using the alternative route from A to B?
The Pythagorean theorem will be needed in this problem. Once you use the Pythagorean theorem , you will get the length of AB, but this question goes a little further, it wants the DIFFERENCE of AB from the SUM of AC and CB
