I think it’s D I don’t know
Answer:
9x^2 +12
Step-by-step explanation:
The area of a rectangle is given by
A = l*w
= 3 *(3x^2 +4)
Distribute
= 9x^2 +12
Answer:
60°
Step-by-step explanation:
Since this is an equilateral triangle all the angles and sides are the same.
180÷3=60°
All the angLes will be 60°, because in a triangle ball angles must add up to 180°.
Hope this answers your question.
Given that, = 39
We will find the second term
Similarly,
Now we use the option checking method,
Suppose we check 4th option
a_{n}= 6n + 33
for n=1
= 6(1) + 33 = 39
It means option D is correct
