Since we don't want to use the Pythagorean Theorem on all of these, first we look for some Pythagorean Triples. Its very helpful to know some of the common ones, so here's a list:
3, 4, 5
5, 12, 13
7, 24, 25
8, 15, 17
So we either look for these or a multiple of these numbers.
The last one is the only one that fits because 15, 20, 25 is a multiple of the triple 3, 4, 5 by multiplying all of them by 5.
Thus, 15, 20, 25 forms a right triangle.
First 8-3
next 4^4
then 16-6
last 10+5
you should get 15
Clean up the equation with x first and x=12.
Substitute this value in to the other equation to solve for y.
You should get a solution of (12,-8)
Answer:
6 +4 (11-2)
6 + 4 (9)
6+ 36
42
42÷3²
42÷9
4.6666667
Step-by-step explanation:
i hope the divided by 3^2 was the next step and not a part of the equation because if it was a part of the original equation than the answer is wrong
Answer:
67 inches
Step-by-step explanation:
Let's call the height of Louise 'L', the height of Miriam 'M' and the height of Jeffery 'J'.
Then, we can write the following equations and inequations:
Substituting J in the second and four inequations, we have:
If we assume the maximum value for M, in the first inequation we have that:
So the height of Uncle Louise is greater than or equal 66, and lesser than or equal 68, so his height could be 67 inches for example.
