Simplify the expression. write the answer using scientific notation. (9 x 10^5) (3 x10^10)

Should be 2.7 x 10^16

Step-by-step explanation:

(9 x 10^5) (3 x10^10)

Multiply 9 by 3

9 x 3 = 27

Add the exponents

10^5 + 10^10

Results in

27 x 10^15

However that isn't an answer choice. But 2.7 x 10^16 is the same as 27 x 10^15

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2

the answers might not be correct use at own risk

correct answer is option b.

step-by-step explanation:

the true statement about geometric figure is option b that is one line can be drawn through all three points.

if three points are on the same plane, they can be connected by a line.
