Given:
• AD = 3
,• DC = 27
,• BD = x + 3
Let's solve for x.
To solve for x, apply the altitude formula:
Where BD is the altitude.
Cross multiply:
Plug in the values and solve for x:
Take the square root of both sides:
Therefore, the value of x is 6 .
ANSWER:
d. 6
Answer:
= 9
Step-by-step explanation:
Note there is a common ratio r between consecutive terms of the sequence, that is
r = 18 ÷ 2 = 162 ÷ 18 = 1458 ÷ 162 = 13122 ÷ 1458 = 9
A recursive formula allows a term in the sequence to be found by multiplying the previous term by the common ratio, that is
= 9
with a₁ = 2
