You need only set up a proportion.
11 cm/16.5 cm = 4 cm / x Cross multiply
11x = 16.5 * 4
11x = 66 ' Divide by 11
x = 66/11
x = 6
The expanded height is 6 cm Answer
Answer:
5+ 4x > 7, x > 1/2

Answer:
= 40n + 20
Step-by-step explanation:
there is a common difference between the first 3 terms in the sequence, that is
100 - 60 = 140 - 100 = 40
This indicates the sequence is arithmetic with nth term
= a₁ + d(n - 1)
a₁ is the first term , d the common difference, n the term number
here a₁ = 60 and d = 40 , then
= 60 + 40(n - 1) = 60 + 40n - 40 = 40n + 20
