Answer:
x = 12, y = 16
Step-by-step explanation:
Since the figures are similar then the ratios of corresponding sides are equal, that is
=
, substitute values
=
( cross- multiply )
18(2x + 6) = 540 ( divide both sides by 18 )
2x + 6 = 30 ( subtract 6 from both sides )
2x = 24 ( divide both sides by 2 )
x = 12
-------------------------------------------
and
=
, substitute values
=
( cross- multiply )
27y = 432 ( divide both sides by 27 )
y = 16
Answer:

Step-by-step explanation:
1: find the perpendicular gradient - this is the negative reciprocal of the original gradient:

2: Substitute in the coordinate to find the value of c:

3: Put it all together:

(2^3)=2*2*2=8
(2^-7)=1/2*1/2*1/2*1/2*1/2*1/2*1/2=1/128
8*1/128=1/16=.0625
0-449 is the most reasonable bc of how much the shipping costs
Answer:
All of them would be under $65
