When Albert flips open his mathematics textbook, he notices that the product of the page numbers of the two facing pages is 156. Which equation could be used to find the page numbers that Albert is looking at?

a. x+(x+1)=156
b.(x+1)+(x-2)=156
c.(x+1)(x+3)=156
d.x(x+1)=156

its D

thank you!

well, product implies the multiplication of two numbers

so that eliminates answers "a" and "b" because those are addition

then i said one page was equal to "x"
and then the next page would be "x+1" because its number is one unit greater than the other because its only one page more

therefore its
x(x+1)

no problem!

why is it D?

yas queen i got it right

To solve this problem, let's break down the information given. We know that the product of the page numbers of two facing pages is 156. Let's assume that the first page number is x.

The page numbers of two facing pages are consecutive numbers, so the second page number will be x + 1. Multiplying these two page numbers together should give us 156.

Using this information, we can set up the equation as follows:
x * (x + 1) = 156

Now, let's analyze the answer choices:
a. x + (x + 1) = 156: This equation adds x with x + 1, which is not what we want to do. We want to multiply x by (x + 1).

b. (x + 1) + (x - 2) = 156: This equation adds x + 1 with x - 2, which is not relevant to the problem.

c. (x + 1)(x + 3) = 156: This equation multiplies x + 1 with x + 3, which is not accurate. We want to multiply x by (x + 1).

d. x(x + 1) = 156: This equation multiplies x by (x + 1), which matches the problem statement. Therefore, the correct equation is d. x(x + 1) = 156.

By solving this equation, you can find the values of x and x + 1, which will give you the page numbers Albert is looking at.
