1835008

Step-by-step explanation:

The n th term of a geometric sequence is

= a

where a is the first term and r the common ratio

Here a = 7 and r = 28 ÷ 7 = 4, thus

= 7 = 7 × 262144 = 1835008

area = length x width

length = 2 x width

32 = 2 x width x width

32 = 2 x width^2

36 = width ^2  

width = 6

length = 12

area is 32

perimeter = 2 x 12 + 2 x 6 = 24 + 12 = 36

step-by-step explanation:

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
