Divide the figure into a triangle on the left and a rectangle on the right. You know the side lengths of the rectangle are 3 x 10, so multiply to get the area of the rectangle. Next, find the area of the triangle. The area of a triangle is given by 1/2bh, where b is the base and h is the height. Because you know the short side of the rectangle is 3, subtract 3 from 5 to get the base of the triangle. then multiply that by 10, the height, and divide by 2 to get the area of the triangle. Then just add up the area of the triangle and the area of the rectangle to get your answer :)

1) Cancel out the common factor which in this case is 8 \frac{16m^2}{24m^7} = \frac{2m^2}{3m^7}

2)First apply exponent rule \frac{n(n+7)}{4n(n+7)}\\ now cancel out the common factors which are n and n+7 leaving you with \frac{1}{4}=0.25

3)Factorize \frac{(x+2)(x-12)}{x+2}cancel out the common factor in this case x+2 leaving you with x-12

4) Factorize \frac{(-3w+1)(3w-1)}{4(3w-1)} cancel out the common factor in this case 3w-1 leaving you with \frac{-3w+1}{4}

5) In the picture

6)In the picture

I am REALLY tired sorry I wont be able to do the rest, I hope these are helpful :)

Choose the explicit and recursive formulas for the geometric sequence 45, 135, 405, 1215, 3645, .... PLEASE HELP ASAP
sesenic [268]

Answer:

Option (B)

Step-by-step explanation:

Given sequence is 45, 135, 405, 1215, 3645..........

Since it's a geometric sequence,

Common ratio of each successive term to the previous term

r = \frac{135}{45}=3

First term of the sequence 'a' = 45

Explicit formula of a geometric sequence will be,

a_n=a(r)^{n-1}

a_n=45(3)^{n-1}

Recursive formula of this sequence will be,

a_n=3(a_{n-1}), a_1=45

Therefore, Option (B) will be the answer.
