What is the value of X

The letter "x" is often used in algebra to mean a value that is not yet known.

Step-by-step explanation:

x = 24

Step-by-step explanation:

∠ 13 and ∠ 14 are adjacent angles on a straight line and sum to 180° , then

4x + 11 + 3x + 1 = 180 , that is

7x + 12 = 180 ( subtract 12 from both sides )

7x = 168 ( divide both sides by 7 )

x = 24

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2

if you are looking for the unit rate then the answer would be 9 because unit rate is distance divided by time.
