Answer:

The correct answer is Choice C.

Step-by-step explanation:

When figuring out the perimeter, we need to count the number of sides. There are 8 sides in total. 5 sides have length labeled 'x' . 2 sides have the length labeled 'y' . Only 1 side has the length labeled 'z' .

In order to put that into an expression, just add the sides up.

5 sides of z + 2 sides of y + 1 side of z

Therefore, the expression that represents the perimeter of the figure is 5x + 2y + z.

What are the roots of the quadratic equation below? x2 + 2x= -5

muminat

Answer:

No real root.

Complex roots:

$x = -1 \pm 2i$

Step-by-step explanation:

$x^2 + 2x = -5$

$x^2 + 2x + 5 = 0$

There are no two integers whose product is 5 and whose sum is 2, so this trinomial is not factorable. We can use the quadratic formula.

$x = \dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a}$

$x = \dfrac{-2 \pm \sqrt{2^2 - 4(1)(5)}}{2(1)}$

$x = \dfrac{-2 \pm \sqrt{4 - 20}}{2}$

$x = \dfrac{-2 \pm \sqrt{-16}}{2}$

Since we have a square root of a negative number, there are no real roots. If you have learned complex numbers, then we can continue.

$x = \dfrac{-2 \pm 4i}{2}$

$x = -1 \pm 2i$

Step-by-step explanation:

substitute x to 150

=0.00125(x)^4+x-3

=0.00125(150)^4+150-3

WE ARE USING PEDMAS HERE SO BE CARE-FULL parenthesis,exponent,multiplication,division,addition,subtraction

=0.00125(506250000)+150-3

=632812.50+150-3

=632962.50-3

=632959.50
