Answer:
4x² - 4x - 1
Step-by-step explanation:
Given
4(x² - 2x) + (x - 1)(x² + x + 1) - x(x² - 4) ← distribute all parenthesis
= 4x² - 8x +x ³ + x² + x - x² - x - 1 - x³ + 4x ← collect like terms

for the function f(x)= -3x+3 find f(0)
Answer:
3
Step-by-step explanation:
We have been given a function as; f(x)= -3x+3. then it is found that f(0) = 3
What is a function?Function is a type of relation, or rule, that maps one input to specific single output.
We have been given a function as;
f(x)= -3x+3.
then we need to find the function when x is equal to zero.
If f(x) = -3x + 3, this means that any number that replaces x in the parenthesis, would replace x in the right side too.
When x = 0:
f(0) = -3(0) + 3 = 3
f(0) = 3
Therefore, We have been given a function as; f(x)= -3x+3. then it is found that f(0) = 3

Reflect (7,3) across the y-axis.
Then reflect the result across the y-axis again.
What are the coordinates of the final point?
Answer:
(7, 3)
Step-by-step explanation:
If we reflect a point/figure across the y-axis, the rule is (x, y) -> (-x, y).
(7, 3) -> (-7, 3)Now, let's reflect it against the y-axis again.
(-7, 3) -> (7, 3)As you can see, we're back to where we started- at (7, 3). Thus, we can conclude that reflecting across the y-axis twice will result in the original point/figure.

A metal bar is L cm long when its temperature is T◦C. The quantities L and T are
approximately related by the formula L = 0.002T + 25.
L is a function of T and the rule can be written L(T) = 0.002T + 25. State a possible
practical domain for the function.
A possible practical domain for the function is T > 12500
How to find the domain of a functionThe domain are the input values for which a function exist.
Given the function relating the metal bar is L cm long when its temperature is T◦C as:
L(T) = 0.002T + 25
The domain of the expression is the point where 0.002T + 25 is greater than zero.
0.002T + 25 > 0
0.002T > -25
T > 12,500

Hope it helps!!!Brainliest pls!!!the sum of 2 times a number and 10 is the same as 6 times the difference of the number and 1. what is the numner ?
Answer:
the number is 4
Step-by-step explanation:
let the number be x
2x + 10 = 6(x - 1)
2x + 10 = 6x - 6
minus both sides by 2x
10 = 4x - 6
add both sides by 6

Work out the width of the rectangle, marked x on the diagram.
cm.
Round your answer to 1 decimal place.
Help!!!
Answer:
Step-by-step explanation:
Note:
Circumference of a circle = [tex]\pi d[/tex]
Where d = diameter
We are given the diameter is 20cm, d = 20
Circumference of circle = [tex]\pi d[/tex] = 20 [tex]\pi[/tex]
Also, perimeter of a rectangle = 2 times length + 2 times width
We are told the length = 18 , width = x
Perimeter of rectangle = 2 times 18 + 2 times x
Perimeter of rectangle = 36 + 2x
The question also tells us that the circumference of the circle is EQUAL to the perimeter of the rectangle:
So this means:
Since Circumference of circle = 20[tex]\pi[/tex] ,
Perimeter of rectangle = 36 + 2x .
We can write:
Circumference of circle = perimeter of rectangle
20[tex]\pi[/tex] = 36 + 2x
Subtract 36 from both sides
20[tex]\pi[/tex] - 36 = 2x
Divide both sides by 2 to solve for "x".
x = [tex]\frac{20\pi - 36 }{2} = ?[/tex]
