Answer:
Step-by-step explanation:
<u>The scale factor is:</u>
Applied to the area we consider k² as the area is the product of two dimensions.
<u>Find the actual area:</u>
- 0.25 m² : (1/400)² =
- 0.25 m² * 160000 =
- 40000 m² =
- 40000 * 1/10000 hectares =
- 4 hectares
We would plug in x to all of those equations. So, 3(4+4)(4+1)/(4+2)(4-2). This would be 3(8)(5)/(6)(2). Then multiply them. 3(8)(5) would be 120. (6)(2) would be 12. Then divide 120 and 12 to get 10.
Is in mathematics means the equal sign
of in mathematics means multiplication
So translating that sentence into an algebraic expression, it would be:
0.04 = 1/10 x 0.4
And that statement is true! Because when you divide a number by 10, you move the decimal over to the left one time.
