Answer:

Step-by-step explanation:
we know that
If rectangle ABCD is similar to rectangle ZBXY
then
the ratio of their corresponding sides is equal and is called the scale factor
so

in this problem we have



Substitute the values and solve for CD



1) 4x + 12x² + 9 + 3y + 2x + 11y
6x + 12x² + 14y + 9
2) x² + 2y + 15x² + 4x + 21
4x + 16x² + 2y + 21
3) 8x + 12 + 17y + 3x + y + 8
11x + 18y + 20
Hope this helps :)
Answer:
Step-by-step explanation:
You and your friends = 4
Appetizers = 8*3 $ (3 appetizers)
Deserts = 4*2 $ (2 deserts)
Bill = 8*3 + 4*2
= 24 + 8
= 32 $
Each pays equally
= 32 / 4. ( 4 people are there)
= 8
So, you and your friends need to pay 8$ each to pay bill
Answer:
11.39
Step-by-step explanation:
-3.86+6.82=2.96
abs(2.96)=2.96
----------------------
4.02-12.45=-8.43
abs(-8.43)=8.43
-----------------------
1(2.96)+8.43=2.96+8.43=11.39
