How many cubes are needed to build this structure? 8 7 10 9

Option A. 8 cubes

Step-by-step explanation:

In the given structure we can count the cubes by dividing the figure in three sub parts.

Two in L shape and one below on L shape figure.

Two L shape figure contains 2×3 = 6 cubes

Cubes hidden under one L shape = 2

Then total cubes = 6 + 2 = 8

Option A. 8 cubes is the answer.

answer: there are x+184 pages in olivia's book.

step-by-step explanation:

let the total number of pages in the book which olive has already read be x.

then if olive has 184 pages left to read, then the total number of pages are in olive's book= pages she has read+pages she has left to read

therefore, the total number of pages in olivia's book=

hence, there are x+184 pages in olivia's book.

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4
