Answer:

1.2 ounces of each bracelet is made up from wire.

Step-by-step explanation:

2.2 x 2 = 4.4

6.8 - 4.4 = 2.4

2.4 / 2 = 1.2

Solve this equation for y. <br> 3x - 5y = 12
Volgvan
-5y=12-3x (subtract 3x from both sides)
y = - 12-3x/5 (divide both sides by -5)
y = - 3(4-x)/5 (common term is 3)

Two of the three sides of a triangle are 20 and 15. Which of the following numbers is not a possible perimeter of the triangle?
fgiga [73]
e. 72.

Let x be the measurement of the 3rd side.

x should be greater that the difference of 2 sides
x should be less than the sum of 2 sides

20 - 15 < x < 20 + 15
5 < x < 35

We can assume that x = 35 the maximum measurement of the 3rd side.

Perimeter = 20 + 15 + 35 = 70. Maximum perimeter.

Among the choices, 72 is beyond the maximum, so it is not a possible perimeter of the triangle.

Factor x^4 + xy^3 + x^3 + y^3. Hint, first factor a monomial. Please explain why!!!
almond37 [142]

Pull an x from the first two terms

x(x^3 + y^3) + (x^3 + y^3)   Now x^3 + y^3 is a common factor.

(x^3 + y^3)*(x + 1) That should be far enough. It can be factored further by factoring (x^3 + y^3) but there is no point because you can't do anything after that. But in case you want to know how x^3 + y^3 factors

(x^3 + y^3) = (x + y)(x^2 - xy + y^2)

Which means you could write original polynomial as

(x + y)(x^2 - xy + y^2)(x + 1)

Part B

You factored the x out of xy^3 so that you would have a common factor (x^3 + y^3) to pull out as a common factor for the whole polynomial.
