Help me pls im getting confused. A) 50*9=450 (i dont need help on this)
B) 450 divided by 21= 21.42 (i dont need help on this)

C) Suppose the scale factor you will use to enlarge the map is 5:1. What is the approximate area of the park in your enlarged drawing? Show your work (help)

hi,

i'm 75% sure the answer is 1,1 to both lines.

have a great day

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.

yes   because as the functions are graphed they eventually will intersect unless otherwise

step-by-step explanation:

hello from mrbilldoesmath!

answer:

(7 x + 6 y) (49 x^2 - 42 x y + 36 y^2)

discussion:

the trick is to recognize that 343 = 7^3 and 216 = 6^3 and, in general,

a^3 + b^3 =   (a + b) (a^2 - a b + b^2).

in our case

343x^3+216y^3   =   (7x)^3 + (6y)^3

so take a = 7x and b = 6y in the above equation to get the answer.

you,

mrb
