Answer:
4x^3 -12x^2 +17x -12
Step-by-step explanation:
Use the distributive property, and collect terms.
(2x -3)(2x^2 -3x +4)
= 2x(2x^2 -3x +4) -3(2x^2 -3x +4)
= 4x^3 -6x^2 +8x -6x^2 +9x -12
= 4x^3 -12x^2 +17x -12

How do you find the sum of the exterior angle measures of any convex polygon?
If the polygon is regular, how do you find the measure of each exterior angle in the polygon?
Answer:
If a polygon is convex, then the sum of the measures of the exterior angles, one at each vertex, is 360° .
Consider the sum of the measures of the exterior angles for an n -gon.
N=180n−180(n−2)
Distribute 180 .
N=180n−180n+360 =360.

Answer:
b = 16.5; 13; 9.5; 6; 2.5
Step-by-step explanation:
Subscribe the given information to get an Answer.
b = 39 / 2 - 3 = 16.5
b = 32 / 2 - 3 = 13
b = 25 / 2 - 3 = 9.5
b = 18 / 2 - 3 = 6
b = 11 / 2 - 3 = 2.5
Given the functions f(x) = 7x 13 and g(x) = x 2, which of the following functions represents f[g(x)] correctly? f[g(x)] = 7x 15 f[g(x)] = 7x 27 f[g(x)] = 7x2 15 f[g(x)] = 7x2 27.
Function represent relationship between variables. The value of f[g(x)] when f(x) = 7x+13 and g(x) = x+2 is 7x+27.
What is Function?A function assigns the value of each element of one set to the other specific element of another set.
Given to us
f(x) = 7x+13
g(x) = x+2
In order to find the value of f[g(x)], we will substitute the value of g(x) at the place of x in f(x).
[tex]f[g(x)] = 7(x+2)+13 \\\\ f[g(x)] = 7x+14+13 \\\\ f[g(x)] = 7x + 27[/tex]
Hence, the value of f[g(x)] when f(x) = 7x+13 and g(x) = x+2 is 7x+27.

The border around a picture has the same width all the way around. The perimeter of the picture is 123 cm and the perimeter of the outside of the picture frame is 191 cm. Find an equation that can be used to find to find the width of the border around the picture?
Answer:
2x +2y= 123, or
8a +2x +2y= 191
Step-by-step explanation:
Perimeter of rectangle= 2(length) +2(width)
Let the length and the width of the picture be x and y respectively.
Perimeter of the picture= 2x +2y
2x +2y= 123 -----(1)
Let the width of the border be a.
Length of picture frame= a +x +a= 2a +x
Width of the picture frame= a +y +a= 2a +y
Outer perimeter of the frame= 191
2(2a +x) +2(2a +y)= 191
Expand:
4a +2x +4a +2y= 191
8a +2x +2y= 191 -----(2)
Substitute (1) into (2):
8a +123= 191
8a= 191 -123
8a= 68
a= 68 ÷8
a= 8.5 cm
Thus the width of the border is 8.5 cm.

Write the next three terms of the arithmetic sequence.
Given that u =< 2,12 >, and z =< -7,5 >
If w = u + z, what is the value of || w ||? (answer should be accurate to 3 decimal places
Using the dot product:
For any vector x, we have
||x|| = √(x • x)
This means that
||w|| = √(w • w)
… = √((u + z) • (u + z))
… = √((u • u) + (u • z) + (z • u) + (z • z))
… = √(||u||² + 2 (u • z) + ||z||²)
We have
u = ⟨2, 12⟩ ⇒ ||u|| = √(2² + 12²) = 2√37
z = ⟨-7, 5⟩ ⇒ ||z|| = √((-7)² + 5²) = √74
u • z = ⟨2, 12⟩ • ⟨-7, 5⟩ = -14 + 60 = 46
and so
||w|| = √((2√37)² + 2•46 + (√74)²)
… = √(4•37 + 2•46 + 74)
… = √314 ≈ 17.720
Alternatively, without mentioning the dot product,
w = u + z = ⟨2, 12⟩ + ⟨-7, 5⟩ = ⟨-5, 17⟩
and so
||w|| = √((-5)² + 17²) = √314 ≈ 17.720

anna is on a road trip. she uses 3/4 of a tank of gas every 9/2 hours. How many tanks of gas will anna use after 12 hours?
Answer:
Step-by-step explanation:
This is a proportional question. If you learn how to keep things together, they are not only easy to do, they are mechanical: they are all done exactly the same way.
tanks of gas different tanks of gas
========== = ================
hours different hours.
initial tank of gas = 3/4 tank
initial hours = 9/2 = 4.5 hours
final tanks of gas = X
final time = 12 hours.
Solution
3/4 x
==== = ==============
4.5 12
Cross multiply
4.5x = 12*3/4 Combine the right
4.5x = 36/4 Simplify
4.5x = 9 Divide both sides by 4.5
x = 9/4.5
x = 2
So she will need 2 tankfuls.

Answer:
8.2 units
Step-by-step explanation:
Given that the only information for our triangle are 2 sides and 1 angle, we must use the Law of Cosines to find side BC

How do I find the equation of a line?
Can i have an easy method for this pls tyy!
Answer:
Steps to find the equation of a line from two points:
Find the slope using the slope formula
Use the slope and one of the points to solve for the y-intercept (b).
One of your points can replace the x and y, and the slope you just calculated replaces the m of your equation y = mx + b. Then b is the only variable left. Use the tools you know for solving for a variable to solve for b.
Once you know the value for m and the value for b, you can plug these into the slope-intercept form of a line (y = mx + b) to get the equation for the line.
Step-by-step explanation:
Well this is my way lol
mark brainliest if u want to cuz i need 5 more :)
Answer:
Step-by-step explanation:
You usually need to find the slope first.
When you have more than two points, you use the slope-intercept formula.
When you have one point and a slope, you use point-slope formula.

The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure
Given is a parallelogram ABCD.
Now, we can state that -
∠A = ∠C
(y + 10) = (2y - 40)
y + 10 = 2y - 40
y = 50
{Opposite angles are congruent}
(4x) + (2y - 40) = 180
4x = 180 - 60
4x = 120
x = 30
{Consecutive angles are supplementary}
Therefore, we can conclude that -
