The answer will be the last one as it equals 4x + 3. this means that the equation will be parallel and does not have a solution.
( x + 5 ) ( x - 7 )
( x ) ( x ) + ( x ) ( - 7 ) + ( 5 ) ( x ) + ( 5 ) ( - 7 )
x² - 7x + 5x - 35
= x² - 2x - 35.
Largest doll = 12 inches
2nd doll = (12) x 0.7
3rd doll = (12 x 0.7) x 0.7
4th doll = [(12 x 0.7) x 0.7) x 0.7
So, the height of the nth doll can be expressed as: 12 x 0.7^(n-1)
Example: 4th doll = 12 x 0.7^(4-1) = 12 x 0.7^3
Answer:
the second answer choice, 3 4/5
Step-by-step explanation:
6 - 2.2= 3.8
3.8 = 3 8/10 = 3 4/5
