In a recent year, the population of California was about 2.52 x 10^7 people. Its land area is about 4.05 x 10^5 km^2. What was t
andrezito [222]

The population of California = 2.52 \times 10^7 people.

Land area of California = 4.05 \times 10^5km^2.

We have to determine the average number of people per square kilometer.

Average number of people per square kilometer =

Land area of California \div Population of California

= 4.05 \times 10^5 \div 2.52 \times 10^7

= 1.6 \times 10^{-2}

Therefore, the average number of people per square kilometer is  1.6 \times 10^{-2}.

It is represented in scientific notation as Scientific notation is a way of writing very large or very small numbers. A number is written in scientific notation when a number between 1 and 10 is multiplied by a power of 10.

X + (2x + 5) = 3(x – 4)+7
eduard

Answer:

Not true

Step-by-step explanation:

x + (2x + 5) = 3(x – 4)+7

Opening bracket on left and side and distributing 3 over (x-4) on right hand side

x+2x+5=3x-3 x 4 + 7

adding like terms

3x+5=3x-12+7

3x+5=3x-5

Hence

5 = -5

Which is not possible , Hence the equation given to us is false.
