\frac{\frac{x+4}{x^2-16}}{\frac{x^2-1}{x^2+3x-28}}\\=\frac{x+4}{(x+4)(x-4)}\times\frac{(x-4)(x+7)}{(x-1)(x+1)}\\=\frac{x+7}{x^2-1}

Choose a variable to represent one of the unknowns. Express the remaining unknowns in terms of the variable you chose in step 1.

Let's just choose "x" as our variable for the length of a side of the triangle.

Two sides of a triangle are equal in length and double the length of the shortest side.

A triangle has 3 sides. Make the smallest side x then the two equal sides that are double the smallest side are both equal to 2x

The perimeter of the triangle is 35 inches. Perimeter is the sum of all sides.

x + 2x + 2x = 35

5x = 35

x = 7

So the smallest side is 7, and the other two sides are 14.

Answer:

x^2-4x+3

Step-by-step explanation:

Since the zeroes of the quadratic are 1 and 3, we can set up an equation in factored form:

(x-1)(x-3)

=x^2-4x+3

We can further check that this is the right answer by evaluating it at the vertex:

(2)^2-4*2+3=-1

Since that corresponds to the graph, the answer is x^2-4x+3

nata0808 [166]

Answer:

  16/15

Step-by-step explanation:

  \dfrac{-3}{5}\cdot\dfrac{2}{-9}\cdot 8=\dfrac{3\cdot 2\cdot 8}{5\cdot 9}=\dfrac{2\cdot 8}{5\cdot 3}=\dfrac{16}{15}

The two minus signs cancel, so the result is positive.
