<span>A rational number can be written in the form:
</span>
<span>
The number
isn't equal to zero because the division by zero is not defined. So we can represent rational numbers by a repeating or terminating decimal, for instance in the following four exercises we have:

Let's say that number is hmmm "a"
now.. twice "a" is 2*a or 2a
4 less than that is " 2a - 4"
now, the product of those two fellows is 286, well ok
a( 2a - 4) = 286
thus
Answer:
A
Step-by-step explanation:
Cosine is the ratio of "adjacent" to "hypotenuse"
With respect to the Angle E, the adjacent side is FE and the hypotenuse (always opposite side to 90 degree angle) is DE.
We are given DE = 26, but we need FE. We will solve for FE using Pythagorean Theorem, which tells us:
leg^2 + another leg^2 = hypotenuse^2
So, we will have:
10^2 + FE^2 = 26^2
Now, we solve for FE:
So,
Cos(E) = adj/hyp = 24/26
Correct answer is A
Answer:
(m+n)/10
Step-by-step explanation:
divide 10 by the sum of n and m
(m+n)/10
2(7x - 3) = 9
step 1 : distribute thru the parenthesis......14x - 6 = 9
step 2 : add 6 to both sides.......14x = 15
