Answer:
3x² + 2x -16
Step-by-step explanation:
(3x+8)(x-2)
=> 3x(x) + 3x(-2) + 8(x) + 8(-2)
=> 3x² - 6x + 8x - 16
=> 3x² + 2x -16
The expanded form of the trinomial (3x+8)(x-2) is 3x² + 2x -16
To expand the trinomial (3x+8)(x-2), we can use the distributive property.
First, we multiply the first terms of each binomial: 3x * x = 3x^2.
Next, we multiply the outer terms: 3x * -2 = -6x.
Then, we multiply the inner terms: 8 * x = 8x.
Finally, we multiply the last terms of each binomial: 8 * -2 = -16.
Putting it all together, we have:
(3x+8)(x-2)
=> 3x(x) + 3x(-2) + 8(x) + 8(-2)
=> 3x² - 6x + 8x - 16
=> 3x² + 2x -16

1= 39 degrees
2: 40 degrees
3: 41 degrees
4: 42 degrees
Answer:
A
Step-by-step explanation:
This uses the sine law.
Sin(theta)/113 = sin(42)/120 Multiply both sides by 113
sin(theta) = 113*sin(42)/120
sin42 = 0.6691
sin(theta) = 113 * 0.6691 / 120
sin(theta) = 0.630008
theta = sin-1(0.63008)
theta = 39.1 Looks Like A
the equation f(x)=|4x+3|+2 translated 2 units down is g
Answer:
g(x) = |4x+3|
Step-by-step explanation:
Vertically translate f(x) two units down by subtracting 2 from f(x).
|4x+3|+2-2 = |4x+3|
f(x) = |4x + 3| + 2
To translate 2 units down, subtract 2
f(x) = |4x + 3| + 2 - 2
f(x) = |4x + 3|
how do you solve 11=t+11.5-t?
Equations are represented with the = sign. It means both sides of the equation are equal. [tex]11=t+11.5-t[/tex] has no solution
Given that:
[tex]11=t+11.5-t[/tex]
Start by collecting like terms

Gina rented a truck for one day there was a base fee of 1275 there was an additional charge of 20 cents for each mile driven the total cost c in dollars for driving in miles is given by the following function
Answer:
[tex]1275+0.2m=c[/tex]
m is the amount of miles driven, c is the total cost.
Step-by-step explanation:
Since she has a flat fee of 1275, that's the 1275 in the equation and since we don't know how many miles she drives, that's the m in the equation for miles driven. Since each mile costs 0.20, that's the 0.2 in the equation. And since c is the total cost in dollars, that's the c in the equation.

Which of the following set of points represents a function?
(4,3), (2, 1), (2, 9). (9, 4)
(3,5), (4,5), (5,9), (7.-2)
(-1,2). (-1, 4), (-1,8), (-1,9)
Answer:
Each of the domain values, x, should only output a single unique range value, y.
This example is a relation and not a function because the the domain value of -1 output 2 distinct range values.
-1 outputs a 3
and
-1 outputs a 5
If I were to draw a vertical line at the domain value of -1 that vertical line would intersect the points (-1,3) and (-1,5). Which indicates that the relation is not a function.

None of the following set of points represents a function .
Which One Does Not Belong? EXPLAIN your REASONING
Answer:
The last one
Step-by-step explanation:

The last one ( 3 circles) are 3 wholes.
(whole numbers)
I hope this helped:)...
:-)
Hey there! I'm happy to help!
30% is the same thing as 0.3, which is 30% of 1.
0.3 is what you multiply numbers if you want to see what 30% of that number is as 0.3 is 30% of 1, the whole number.
3/10 is the same value as 30% because 3 divided by 10 is equal to 0.3, which is 30%.
The dots in the boxes are also the same thing as 3/10. There are 10 boxes, and 3 out of the 10 have dots, which is 3/10 and 30%.
The one that does not belong is 0.333333...... This is equivalent to 1/3, which is greater than 30%, 0.3, and 3/10.

Find three consecutive even integers so that twice the largest
is 20 less than the sum of all three
If x is the smallest of the three, then the next two integers are x + 2 and x + 4.
"Twice the largest is 20 less than the sum of all three" translates to
2 (x + 4) = (x + (x + 4) + (x + 6)) - 20
Solve for x :
2x + 8 = 3x - 10
x = 18
Then the three numbers are {18, 20, 22}.
Answer:look below
Step-by-step explanation:Let x, x+2 & x+4 be the 3 integers.
x+2(x+2)=(x+4)+20
x+2x+4=x+4+20
3x+4=x+24
3x-x=24-4
2x=20

8. The difference of thirty-one and seventeen
divided by the product of ten and four
Answer:
[tex]\frac{7}{20}[/tex]
Step-by-step explanation:
The difference 31 - 17 = 14
The product 10 × 4 = 40
Then
[tex]\frac{14}{40}[/tex] = [tex]\frac{7}{20}[/tex] ← in simplest form
The difference between thirty-one and seventeen divided by the product of ten and four will be 7 / 20.
What is Algebra?The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
The difference between thirty-one and seventeen will be expressed as,
⇒ 31 - 17
⇒ 14
The product of ten and four will be expressed as,
⇒ 10 x 4
⇒ 40
Then the difference between thirty-one and seventeen divided by the product of ten and four will be expressed as,
⇒ 14 / 40
⇒ 7 / 20
Thus, the difference between thirty-one and seventeen divided by the product of ten and four will be 7 / 20.
