lets take a look....

In order to find the perimeter of a triangle you have to get the sum of all sides. In other words,

Blue triangle:

$p = (4x +2) + (7x + 7) + (5x - 4) \\ p = 4x + 2 + 7x + 7 + 5x - 4 \\ p = 16x + 5$

Red triangle:

$p = (x + 3) + (2x - 5) + (x + 7) \\ p = x + 3 + 2x - 5 + x + 7 \\ p = 4x + 5$

Difference:

$d = (16x + 5) - (4x + 5) \\ d = 16x + 5 - 4x - 5 = 12x \\ d = 12x$

HELP PLEASE!!!

Answer:

Option A

Step-by-step explanation:

$R = (\frac{V_f-Vi}{V_i} )100$

where,

$V_f$ is the final value

$V_i$ if the initial value

R is the investors rate of return

so,

$R = (\frac{V_f-Vi}{V_i} )100\\\\R=(\frac{1500-1700}{1700})100 \\\\R=(\frac{-200}{1700})100 \\\\R=-11.8\\$

so the investors rate of return is -11.8%

The parent function f(x) = x2 is translated such that the function g(x) = –x2 + 6x – 5 represents the new function.

zhenek [66]

Answer:

g(x) has an axis of symmetry at x = 3.

g(x) is shifted right 3 units from the graph of f(x)

g(x) is shifted up 4 units from the graph of f(x).

Step-by-step explanation:

The parent function is:

$f(x)=x^2$

The transformed function is $g(x)=-x^2+6x-5$ .

This new function can be rewritten in the vertex form as:

$g(x)=-(x-3)^2+4$

This function is obtained by shifting the parent function 3 units right and 4 units up.

The axis of symmetry is x=3;(x=h) and h=3.

There is no horizontal stretch or compression.

The new function is however reflected in the x-axis

Describe the solutions for the quadratic equation shown below:

PtichkaEL [24]

The solutions for the quadratic equation 9x² - 6x + 5 = 0 are A. 2 complex roots

To determine the the type of roots the quadratic equation 9x² - 6x + 5 = 0, we use the quadratic formula to find the roots.

So, for a quadratic equation ax + bx + c = 0, the roots are

$x = \frac{-b +/- \sqrt{b^{2} - 4ac} }{2a}$

With a = 9, b = -6 and c = 5, the roots of our equation are

$x = \frac{-(-6) +/- \sqrt{(-6)^{2} - 4 X 9 X 5} }{2 X 9} \\x = \frac{6 +/- \sqrt{36 - 180} }{18} \\x = \frac{6 +/- \sqrt{-144} }{18} \\x = \frac{6 +/- \sqrt{-12} }{18}\\x = \frac{6}{18} +/- i\frac{12}{18} \\x = \frac{1}{3} +/- i\frac{2}{3} \\x = \frac{1 + 2i}{3} or \frac{1 - 2i}{3}$

Since the roots of the equation are (1 + 2i)/3 and (1 - 2i)/3, there are 2 complex roots.

So, the solutions for the quadratic equation 9x² - 6x + 5 = 0 are A. 2 complex roots
