the area of a rectangular cookie sheet is 8x^2+26x+12 . the width of the cookie sheet is 2x+5 . what is the length of the cookie

Illusion [34]

You would lay out the equation for area
A=(L)(W)
then plug in the variables
8x^2+26x+12=2x+5(L)
then solve for L

Charles is reading about computers. He learns that a computer processor can perform one command in approximately 0.000000016

ella [17]

The number 0.000000016 is expressed in scientific notation is:

$1.6 \times 10^{-8}$

Solution:

Given that,

Charlie learns that a computer processor can perform one command in approximately 0.000000016 nanoseconds

We have to express in scientific notation

Step 1:

Given number is:

0.000000016

Move the decimal point in 0.000000016 until there is only one non-zero digit to the left of the decimal point

Here,

Move the decimal 8 places to the right to get 1.6

We have moved the decimal to left, therefore, exponent is negative

$1.6 \times 10^{-8}$

Thus the given number is expressed in scientific notation

HI CAN I PLEASE GET SOME HELP PLEASE THANK YOU I WOULD APPRECIATE IT HOW MANY SOLUTIONS ARE THERE TO THIS NONLINEAR SYSTEM!!!! A

viktelen [127]

Answer:

B) one solution

Step-by-step explanation:

The blue line and the red line cross at only one point so there is one solution. It would be no solution if the blue line never crossed the red line and it would be two or possibly more solutions if the lines crossed more than once.
