Answer:

3.45× $10^{5}$

Step-by-step explanation:

The proper way to put a number in scientific notation is a specific way. So the answer you see above is the proper way you would put a number in scientific notation.

So. Put the decimal in between 3 and 4.

3.45000

Now count from the last 0 to 4. Which is 5. (Scientific notation can only be with 0's not any other number.)

So, it would be:

3.45× $10^{5}$

Hope this helped!

A rectangle has a length of (x + 4) centimeters and a width of 12x centimeters. If the perimeter is 26 centimeters, what is the

mars1129 [50]

Width of rectangle is 8.4 cm

Step-by-step explanation:

Length of rectangle = x+4

Width of rectangle = 12x

Perimeter = 26 cm

We need to find width of rectangle.

The formula used is:

$Perimeter=2(length+width)$

Putting values and finding x first:

$Perimeter=2(length+width)$

$26=2(x+4+12x)$

$26=2(13x+4)$

$26=26x+8$

$26-8=26x$

$26x=18$

$x=\frac{18}{26}$

$x=0.7$

So, value of x is 0.7

Now width= 12x = 12(0.7)

=8.4 cm

So, width of rectangle is 8.4 cm.
