B and D because it doesnt matter how you write the equation you still get the same answer,
don't forget to rate my answer 5 stars and thank me
18*3 = 54
20*3 = 60
so the scale drawing would be 54cm x 60cm
Ay^2+2ay-3a
a(y^2+2y-3)
a(y-1)(y+3)
The rule of geometric sequence is ⇒⇒⇒ a * r^(n-1)
Where a is the first term and r is the common ratio
for the given sequence √5 , √10 , 2√5 , .......
a = √5
r = √10 / √5 = √2
The ninth term = √5 * (√2)^(9-1) = √5 * (√2)⁸ = 16 √5
the correct answer is the third option 16√5
196 3/8 in^3. To get this, multiply all the numbers together. To find volume, the equation is length x width x height.
