Answer: 18
Step-by-step explanation: Factor of 18 are: 1, 2, 3, 6, 9, 18
Factor of 36 are : 1, 2, 3, 4, 6, 9, 12, 18, 36
Hope that helps
Cosα=x/L
x=Lcosα, we are told the ladder is 10ft and α=42.5 so
x=10cos42.5° ft
x≈7.37 ft (to nearest hundredth of a foot)
Answer:
the answer is bbbbbbbbbbbb and that is because i GUESS
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) :)
Answer:
(0, 5) and (5,0) are two possibilities.
Step-by-step explanation:
There is an infinite number of ordered pairs that satisfy your inequality.
To help you pick some ordered pairs, you could plot the inequality (see the graph below).
Any point within the shaded area is a solution.
Pick an ordered pair, insert it into the equation, and check if the inequality is true.
Here are two examples.
<em>For (5, 0</em>):
0 – 3×5 < 10
0 - 15 < 10
-15 < 10 True
<em>For (0, 5)</em>:
5 – 3×0 < 10
5 – 0 < 10
5 < 10 <em>True
</em>
The ordered pairs (0, 5) and (5,0) are part of the solution set of the equation y – 3x < 10.
