Algebra question I don’t get it because you usually have to multiple A by C but there is no C in the problem.

Answers

Answer 1

Ok so basically, when you say multiply A by C, that is simplifying.

And in this case, you are factorising in this question. You turn back into brackets basically.

We have:
72x^2 - 32

x^2 = x squared

factorising means finding the factor of.

(Forget the x squared for the moment to make life easier)

Factors of 72:
1 and 72
2 and 36
3 and 24
4 and 18
6 and 12
8 and 9
(9 and 8 = it repeats so we stop there)

And then factors of 32:
1 and 32
2 and 16
4 and 8
(8 and 4 = repeats so we stop there)

Notice how we see 8 twice in both factors of 72 and 32, this means that we use 8 as the main number we are going to multiply each of the 2 numbers in the brackets by. This is because it is the biggest common factor - this is what we have!

This is what we would have:
8(9-4)

BUT, that is not the answer!
Keep in mind we have the x squared too

But, 32 doesn’t have it?!!

It would be:
8(9x^2 - 4)

Do you get it??

Try to simplify it! Does it equal to 72x^2 - 32?

(And I am so very sorry for the long explanation, once you get the hang of it, it makes sense. Hope my explanation helped) :)

Answers

I believe by asking you to do all multiplication first they are asking you to demonstrate the distributive property, this means we can distribute the 9 through the parenthesis by multiplying it by each part inside the parenthesis, this gives us:

36x - 36

now we can substitute 5 in for x to get:

36(5) -36

Hayley has $155 in savings, and her brother Hank has $230. Hayley is saving $10 each week, and her brother is spending $15 each week. After how many weeks will their savings accounts have the same amount of money in them?

What is the best way to set up this word problem to solve?

15x+155=230+10x
15 x plus 155 is equal to 230 plus 10 x

155−15x=10x+230
155 minus 15 x is equal to 10 x plus 230

155+10x=230−15x
155 plus 10 x is equal to 230 minus 15 x

155−10x=230+15x

Keuka Studies does custom metal sculptures of horses and other animals. A horse sculpture is composed of numerous parts. They use a lathe to construct two types of parts. The "Body" part is used to support the torso of the horse and the "Leg" part is used to support the legs. Each horse sculpture needs 1 Body part and 4 Leg parts. Switching between either of the types of parts requires 12 minutes. Once ready to produce, the lathe produces a Body part in 3 minutes and a single Leg part in 3 minutes. The lathe only makes horse parts. For parts (a)-(d) assume Keuka operates a cyclic schedule in which they make 100 Body parts and then 400 Leg parts. Furthermore, assume the lathe is the bottleneck.
