A right triangle can only be formed when you use the 3/4/5 rule.
The 3/4/5 rule is a^2 + b^2 = c^2.
We will use 10 for a, 15 for b, and 20 for c.
a^2 + b^2 = c^2
Plug in 10 for a, 15 for b, and 20 for c.
10^2 + 15^2 = 20^2
10^2 = 100
15^2 = 225
20^2 = 400
100 + 225 = 400
This is not applicable, as 100 + 225 = 325.
Your answer is:
No, 10,15,20 does not form a right triangle.

Answer:
-8
Step-by-step explanation:
Assuming that the in parentheses is what we are supposed to change (3)..We would replace the three with the negative two this means that we will solve for four times -2 which equals -8.Hope this helps!
Answer:
2(x+4)-1=2x+7 is true for everything
Step-by-step explanation:
2(x+4)-1
2(x+4)
=2x+2*4
=2x+8
=2x+8-1
=2x+7
2x+7=2x+7
2x=2x
2x-2x=2x-2x
0=0
true for all x
Answer:
29/4 or 7.25
Step-by-step explanation:
Complimentary angles are two angles that add up to 90
Supplementary angles are two angles that add up to 180
Angle ABC = x
Angle CBD = 7y + 4
Angle DBE = 8y + x
If we can find the measure of angle CBD, then we can find x.
We know that CBD + DBE = 180 because they are supplementary. Therefore...
(7y + 4) + (8y + x) = 180
AND
(7y + 4) + (x) = 90
Now we can use algebra to solve for x and y...
Blah blah blah...
x = 29/4
y = 45/4
The answer would be yes because 935,426>934,578
So change the sign from less than to greater than
Taylor is saying that the population in the year 2000 which was 935426 is greater than the population in the year 2010 which was 934578. It sounds more complicated than it is, they just want you to support Taylor's statement using the population numbers(statistics)
