Answer:
<h3>Step 4</h3>
Step-by-step explanation:
Given the expression 7+(-2)
Let 7 be 7 positive tiles since it is a positive number
Let -2 be 2 negative tiles being a negative number
7+(-2) = 7 positive tiles <em>and</em> 2 negative tiles
note that + * - will give minus sigh (-), the expression will become:
7+(-2) = 7-2
7-2 = 5
Hence the expression gives 5 positive tiles not 2 positive tiles according to Jillian calculations in step 4.
Hence Jillian made an error in step 4
Answer:
I believe the answer is 20
Simple...
you have: 8x-6y=1
To find m (slope) re-write in y=mx+b form
8x-6y=1
8x-6y=1
-8x -8x
-6y=-8x+1
Now simply divide by -6--->>

m=
Thus, your answer.

0 is the perfect square, it is smallest number and it is your answer.
Answer:
21 in
Step-by-step explanation:
The law of cosines is helpful for this. The angle opposite the shorter diagonal is the supplement of the angle shown, so is 60°.
If we designate the known sides as "a" and "b", the short diagonal as "c" and the smaller angle as C, then the law of cosines tells us ...
c^2 = a^2 + b^2 -2ab·cos(C)
For the given dimensions, we have ...
c = √(15^2 +24^2 -2·15·24·cos(60°)) = √441 = 21 . . . inches
