Answer:
$110.46
Step-by-step explanation:
1 bath towel is $15.78 we need 7. So the equation is 15.78 x 7 = 110.76.
To comlete each square, you just have to take the middle term and divide it by 2, then take its square. Add this to both sides of the equation then simplify. The middle term is the 1st degree x variable.
<span>3. x^2+6x =16
-------------------------
(6/2)^2 = 9
x</span>² + 6x + 9 = 16 + 9
(x + 3)² = 25
<span>4. x^2-10x =11
------------------------
(-10/2)</span>² = 25
x² - 10x + 25 = 11 + 25
(x -5)² = 36
<span>5. x^2-9x =0
--------------
(-9/2)</span>² = 81/4
x² - 9x + 81/4 = 81/4
(x - 9/2)² = 81/4
<span>6. x^2+16x =15
---------------
(16/2)</span>² = 64
x² + 16x +64 = 15 + 64
(x + 8)² = 79
<span>7. 3x^2+18x-81=0
----------------
x</span>² + 6x = 27
(6/2)² = 9
x² + 6x + 9 = 27 + 9
(x + 3)² = 36
A polynomial with a general equation of ax² + bx + c = 0 has a root determined using this formula:

Just substitute the coefficients to the formula to find the roots
8. 1.09, -1.84
9. 3, 1/2
10. No real roots
11. 1.12, -3.12
The highest number on dice is 6, so nothing can be higher than 12 when you roll 2 of them...

Answer: she printed 200 programs
Step-by-step explanation:
Let x represent the number of programs that were printed.
The printing cost was $0.32 per program. This means that the total cost of printing x programs would be 0.32 × x = $0.32x
They were priced at $0.50 each. This means that the total revenue from selling x programs is 0.5 × x = $0.5x
Taylor sold all but 50 programs. It means that the number of programs sold is
x - 50 and the total revenue from the number of programs sold is 0.5(x - 50)
Revenue - cost = profit
Taylor made a small profit of $11. It means that
0.5(x - 50) - 0.32x= 11
0.5x - 25 - 0.32x = 11
0.5x - 0.32x = 11 + 25
0.18x = 36
x = 36/0.18
x = 200
