The 2 one jaydjdisgnsjsyhdndisbss.
The answer is $1.80. You would take 25% of 3, which is 75, and subtract it from 3. That leaves you with $2.25, which you take 20% off, which is 0.45, and subtract that from 2.25. That leaves you with a grand total of $1.80. Hope that this helped!
If points (ordered pairs) connected by a line are:
(0,0), (2,6), (4,12), (6,18) and (8,24) [If you did not make a mistake by typing a point (8,27)], THEN
it is a direct proportional relationship in question, defined by formula:
y = k*x
where k is coefficient of this proportion, and x and y are coordinates of points respectively.
So, if you check for EACH point:
0 = k*0,
6 = k*2,
12=k*4,
18=k*6,
24=k*8,
for each of these equations, it is obtained for k to has value of 3.
And the rule is for a proportion, that has to have SAME k value for each of its points on a line.
So the answer is TRUE.
But if you did not make a mistake by typing point (8,27), then k value for its equation
27=k*8, will not be 3 as for the rest of the points.
And then, the answer would be FALSE, it is NOT a proportional relationship.
Answer:
The answer for the missing side length is 16
Step-by-step explanation:
You have to use Pythagorean's Theorem 
is the hypotenuse, which is 20 in this case
is the bottom, which is 12
and you have to solve for 
So
This cancels out the exponent
That's the missing side length
