Rectangle a has length 12 and width 8. rectangle b has length 15 and width 10. rectangle c has length 30 and width 15. is rectangle a a scaled copy of rectangle b? if so, what is the scaled factor?

No.

Step-by-step explanation:

No, because you can multiply or divide the length and breadth of rectangle A by the same number to get B

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50

hello :

by applying the distributive property :

6 × 4.3 = 6 × ( 4 + 0.3 )

            =   (6 ×   4) + (6 ×   0.3)

            = 24 + 1.8

6 × 4.3 = 25.8
