Can anyone clutch I need help with this math problem thanks :) (look at the photo)

2304

Step-by-step explanation:

a1 = 9

a2 = 4*a1 = 4*9 = 36

a3 = 4*a2 = 4*4*a1 = 4*4*9 = 144

a4 = 4*a3 = ... = 4*4*4*9 = 576

a5 = 4*a4 = ... = 4*4*4*4*9 = 2304

in other words

an = a1*4^(n-1)

you have to run through the calculation (in our case a simple multiplication by 4) n-1 times with the starting value of a1.

so, a5 = 9 * 4^4

for example a20 would then be

a20 = 9 * 4^19

a net is a diagram that shows a “flattened” view of a solid. in a net, each face and base is shown with all of its dimensions. a net can also serve as a pattern to build a three-dimensional solid.

a pyramid is a three-dimensional object with a base that is a polygon and triangular faces that meet at one vertex.

" the net of a triangular pyramid consists of four triangles. the base here we are given of the pyramid is a equilateral   triangle, and the lateral faces are also triangles "

the correct answer is you spend $55.78 more in a brand store that buy ing in a normal store.

step-by-step explanation:

brand = spend   $ 135.85 total

store = spend $80.07 total
