Division. Divide 45 by -3
No, if you were to have three right angles, the fourth angle would also have to be a right angle. As a result, it would make the shape either a square or a rectangle.
Answer: 25 < P < 36
15/4 < w < 26/4
35/4 < L < 46/4
<u>Step-by-step explanation:</u>
Perimeter is BETWEEN 25 and 36
25 < P < 36
Graph: O--------------O
25 36
Perimeter = 2L + 2w ; substitute L = w + 5
25 < 2(w + 5) + 2w < 36
25 < 2w + 10 + 2w < 36
25 < 4w + 10 < 36
15 < 4w < 26
< w < 
< w < 
Graph: O------------------------O

Perimeter = 2L + 2w ; L = w + 5 --> w = L - 5
25 < 2L + 2(L - 5) < 36
25 < 2L + 2L - 10 < 36
25 < 4L - 10 < 36
35 < 4L < 46
< L < 
< L < 
Graph: O------------------------O

Note: Make sure you use OPEN dots when graphing.
Answer:
x-7 represents x moved 7 units to the left.
Step-by-step explanation:
The translation: (x, y) → (x - 7, y - 4) was performed on a triangle
x is translated into x-7. 7 is subtracted from x . It means x is moved 7 units to the left
y is translated into y-4. 4 is subtracted from y. It means y is moved 4 units down.
So x-7 represents x moved 7 units to the left.
