Can someone help me out and answer this two questions :P

Question 1: 367.5 ft squared

Question 2: 21.6 miles

Step-by-step explanation:

11. 367.5 sqft   12. 21.6 sqmiles

Step-by-step explanation:

Well for 11. if each inch is 3.5 feet then you would wan t to multiply 5 and 6 by 3.5. You get 17.5 and 21. To find area, you'll have multiply the height and width which is 17.5 and 21. Once you do that you end up with 367.5ft squared.

For 12. each inch is 4.8 mines and there are 4.5 inches. So you want to do 4.5 times 4.8 which gives you 21.6 square miles. I hope you do well.

answer:

(-8,7)

explanation:

we know that  

f

(

−

3

)

=

7

therefore, if we wish to get the output as 7, in the function, we need to have our input to be -3.

looking at the function  

f

(

x

+

5

)

, what should the value of x be, such that the input in the function becomes 7?

we simply equate the terms,

x

+

5

=

−

3

x

=

−

8

thus, the point on the new function would be  

(

−

8

,

7

)

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.
