Answer:
Step-by-step explanation:
To find this equation in standard form, first, write it in factored form. This looks like 
. Then, multiply the polynomials using the FOIL (First, Outside, Inside, Last) method.
- Following the FOIL method, you should multiply the first terms in each binomial,
, which equals 
. - Then, the outside terms,
. This equals 
. - Next, the inside terms,
. - Finally, the last terms,
, this equals 
.
Then, add all of the terms together 
. To get the standard form, combine like terms, this comes out to .
The question is asking to calculate and round of the value in to the greatest non zero place and base on the said number, I would say that the answer would be from 0.64 to 1. I hope you are satisfied with my answer and feel free to ask for more if you have question and further clarification
Answer:32 inches
Step-by-step explanation:
Using the pythagorean theorem
40²= 24²+ b²
simplify
1600 = 576 + b²
subtract 576 from both sides
1024 = b²
square root both sides
32= b
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) :)
One is a and 2 is c that is all
