Answer:
-2x² - 8x + 15 = 0
Step-by-step explanation:
Given the following algebraic expression;
x² – 7x + 5
-3x² - x + 10
To add the equation together;
x² – 7x + 5 + (-3x² - x + 10) = 0
x² – 7x + 5 - 3x² - x + 10 = 0
Collecting like terms, we have;
(x² - 3x²) - (7x + x) + (5 + 10) = 0
-2x² - 8x + 15 = 0
Complete the equation below to make an equation that is equal to 1

Explain how to use the unit-factor method to convert 120 pounds to kilograms.
Hint: 1 kilogram=2.2 pounds
To write the unit factors, use the / symbol, like this: 1 gallon/3.79 liters.
The converted units is 120 pounds = 54.5 kilogram
How to convert the units?As a general rule, we have:
1 kilogram=2.2 pounds
Multiply both sides by 120
120 * 1 kilogram=2.2 pounds * 120
Divide both sides by 2.2
120/2.2 * 1 kilogram=2.2 pounds * 120/2.2
Evaluate the products
54.5 kilogram= 120 pounds
Rewrite as:
120 pounds = 54.5 kilogram
Hence, the converted units is 120 pounds = 54.5 kilogram

The volume of this cylinder is approximately ___ cubic cm.
Use ≈ 3.14. Do not round your answer.
Answer:
Step-by-step explanation:
area of a cylinder = (area of a circle) times the (height)
area of a cylinder = π radius² × height
radius = 57 cm height = 40 cm
area of a cylinder = π 57² cm² × 40 cm
= π (57² × 40) cm³
= π ( 57 × 57 × 40) cm³ 57x57 = 399 + 2850 = 3249
= π (3249 × 40) cm³
= 129969π cm³ π = 3.14
= 129969 × 3.14 cm³
= 408,074.4 cm³ < ----------------- Final Answer

Answer:
201.06 sq. ft.
Step-by-step explanation:
Area of a circle is found by using the equation:
[tex]A = \pi r^{2}[/tex]
Radius = 1/2 (diameter) = 1/2 (16) = 8
So plug in:
[tex]A = \pi (8)^{2}[/tex]
A = 64[tex]\pi[/tex]
A = 201.06193
Rounded A= 201. 06
