Answer:
- 5x² + 6x + 6
Step-by-step explanation:
f(x) - g(x) - h(x)
= 3x + 5 - (4x² - 2) - (x² - 3x + 1) ← distribute parenthesis
= 3x + 5 - 4x² + 2 - x² + 3x - 1 ← collect like terms
= - 5x² + 6x + 6 ← in standard form
Answer:
Step-by-step explanation:
To solve this problem, simply set the binomial, 
as greater than 
, and solve for the value of y as you would solve an equation.
Thus:
Multiply both sides by 4
Subtract 3y from both sides
Add 4 to both sides
Divide both sides by 17
Therefore, the value of y that will make the binomial greater than is .
Answer:
<u>The correct answer is 130.9 kilograms.</u>
Step-by-step explanation:
We want to calculate what is the result of 7.7 kilograms multiplied by 17 and the answer should be in kilograms
Result = 7.7 kilograms * 17
Result = 7.7 * 17
Result = 130.9
Result = 130.9 kilograms
<u>The result of the multiplication of 7.7 kilograms by 17 is exactly 130.9 kilograms</u>

Step-by-step explanation:
Answer:
20 is 80% of 25
Step-by-step explanation:
We assume, that the number 25 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 100% equals 25, so we can write it down as 100%=25.
4. We know, that x% equals 20 of the output value, so we can write it down as x%=20.
5. Now we have two simple equations:
1) 100%=25
2) x%=20
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=25/20
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for 20 is what percent of 25
100%/x%=25/20
(100/x)*x=(25/20)*x - we multiply both sides of the equation by x
100=1.25*x - we divide both sides of the equation by (1.25) to get x
100/1.25=x
80=x
x=80
