Apply x-y intercepts theorem
(x,y)=(0,y) and (x,0).
then substitutes.
Answer:
Please see the attached picture for the full solution.
*From the 4th line of the 1st image, you could also expand it using
(a +b)²= a² +2ab +b² and
(a -b)²= a² -2ab +b².
When squaring a fraction, square both the denominator and numerator.
➣(a/b)²= a²/b²
<span>Using place value to exchange equal amounts when renaming a number is called : Regroup
Simple example for a group is when you try to add up :
86 + 25
86 has 8 group of tens and 6 groups of one
25 has 2 groups of tens and 5 groups of one
after adding that up , now the number has 11 group of tens and 1 group of one, the result of that equation would be : 110</span>
Answer:
17 kilometers
Step-by-step explanation:
The pythagorean theorm is a^2 + b^2 = c^2
In this problem we can call 8 km a and 15 km b.
Plug 8 and 15 into the pythagorean theorm to get 8^2 + 15^2 = c^2
This will give you 289=c^2
Take the square root of both sides to get c=17
Hope this helps!
