Answer: -4,3
Step-by-step explanation: -4,-5 is an x-y coordinate.
Based off of what we have seen on coordinate planes, x is horizontal and y is vertical. So, in order find out a stride north of -4, -5, we need to add 8 to -5, since y is the "north/south" of the equation. So:
-5 + 8 = 3
The point is -4, 3
They’re all -4 ,, what exactly are you asking ?
Professor Dan Healy, one of my Engineering instructors back in prehistoric times, had a favorite way of showing us how to do this kind of problem ... I mean the kind that's incredibly easy, but your own fear gets in the way and convinces you that you can't handle it. Here is Prof. Healy's method.
For a few moments, call the square root of 5 by the name "cow".
cow - x = 4 . Solve this equation for 'x' :
Add 'x' to each side of the equation: cow = 4 + x
Subtract 4 from each side: cow - 4 = x
Now, we can put the real value back in place of 'cow' : <u>√5 - 4 = x</u>
That right there is a perfect solution. But If you absolutely need to
know the number, then grab your calculator:
√5 = 2.2361 (rounded)
x = √5 - 4 = 2.2361 - 4 = <u>-1.7639</u> (rounded)
B, the total area of wall space to be covered.
Perimeter is like fencing, that won't tell us how much wall there is to paint.
