Answer:
The answer would be 40!
Step-by-step explanation:
Estimating ~ rounding
I would round 24% (20%), and 289 (300).
using the formula:
= %/100,
I'm looking for "IS"
I multiply 20 (just 20, no percent) by 200 = 4000.
Then I divide by 100 to get the "IS".
That's how I got my answer!
Hope this helps!
First, we know that y is equal to -8x, so we can move the -8x to replace y in the first equation, then in the first equation we get -8x=6x-14, subtract 6x on both sides, -14x=-14, x=1
Answer:
The factor form is 
Step-by-step explanation:
When it is required to factor the expression given in the problem, we have to first find a common term or terms, which will be found by either grouping the like terms or the splitting of the terms.
Now the expression that is given here is:
Now, here we will take:
Thus we will get:
Now we will do the middle term split as follows:
Substituting back , we will have:
Hence, the required factor form of the given expression will be:
Let the integers be x and x + 2, provided x is even.
x(x + 2) = 360
x² + 2x = 360
x² + 2x - 360 = 0
(x - 18)(x + 20) = 0
x = 18, or x = -20
Thus, the integers are: 18 and 20, or -20 and -18
Answer:
Find the surface area of her notebook.
30 + 30 + 20 + 20 = 100
Now find the surface area of the square stickers.
2 + 2 + 2 + 2 = 8
So this is the surface area of one square, now multiply it by 8.
8 * 7 = 56
This is the surface area of all the stickers, now subtract it to the surface area of the notebook:
100 - 56 = 44
So 44 centimeters of the notebook cover will still be showing.
