Sloan [31]3 years ago

Answer:

a) 2x+2x+x+x+x=42

b) x=6

c) 6 cm, 6cm, 6cm, 12cm, 12cm

Step-by-step explanation:

First think of how you'll get perimeter. Since in the question it says you add all of the sides to get the perimeter, you write the variables being added together and equal it to 42. Next, you add all of the x's together, which you would get 7x=42. Then, you divide 7x and 42 by 7, giving you x=6. Finally, you plug in 6 into the x's, making sure to multiply the ones that are 2(6) into 12. To check if this is true, add the sides together and make sure you get 42.

A graph of a quadratic function y = f(x) is shown below.
spin [16.1K]

We are given a graph of a quadratic function y = f(x) .

We need to find the solution set of the given graph of a quadratic function .

<em>Note: Solution of a function the values of x-coordinates, where graph cut the x-axis.</em>

For the shown graph, we can see that parabola in the graph doesn't cut the x-axis at any point.

It cuts only y-axis.

Because solution of a graph is only the values of x-coordinates, where graph cut the x-axis. Therefore, there would not by any solution of the quadratic function y = f(x).

<h3>So, the correct option is 2nd option :∅.</h3>

muminat

Answer:

$36000

Step-by-step explanation:

We have a mean price of $4500 this means that in the 8 cars we have cars with higer and lower prices than $4500 but that if we have to give the same price to 8 cars that would be $4500. Then to know the total price of the all 8 cars we just have to multiply:

\$4500\cdot 8=$36000
