Answer:
Obtuse Triangle
Step-by-step explanation:
When there is an angle with a measurement greater than 90 degrees, the triangle is an obtuse triangle.
For this case we have:
Cost of manufactures of T-shirts 
where x represents the number of T-shirts
Part A:
Substituting 
in the total cost equation you have to:
Thus, the cost of 8 shirts will be 
Part B:
If 
then
Thus, the cost of 12 shirts will be 
Answer:
Answer:
x = 2
Step-by-step explanation:
1. distribute 9 in 9(x+1)
9x + 9 = 25 + x
2. subtract x from the right side to isolate x onto one side
8x + 9 = 25
3. subtract 9 from the left side
8x = 16
4. divide both sides by 8 to get x alone
x = 2
The answers are:
A) V-Shaped (because absolute value graphs are v-shaped)
C) Opens up (because the leading coefficient is positive)
F) Symmetric with respect to the y-axis (if you look at the graph y= |x|, you see that the y-axis cuts through the middle of the "v-shape", and that it is symmetric)
The polynomial with those roots would be:
<span>y = (x + √5)(x - √5)(x - 3) </span>
<span>▬▬▬▬▬▬▬▬▬▬▬ multiply this out to get </span>
<span>y = (x² - 5)(x - 3) </span>
<span>y = x³ - 3x² - 5x +15</span>
