Answer:
12x² + 3x - 6
Step-by-step explanation: -2x(1-3x) = -2x+6x²
(2x+3)(3x-2), first do 2x
2x × 3x = 6x²
then 2x × -2= -4x
we then move to the number 3
3 × 3x = 9x
3 × -2 = -6
after that we add them together
-2x + 6x² + 6x² - 4x +9x - 6 = 6x² + 6x² is 12x², -2x - 4x + 9x = 3x, and then -6 is by its self
= 12x² + 3x - 6
The simplified solution of the expression is 6x²- 4x - 6.
What is an expression?In mathematics, an expression is a combination of one or more numbers, variables, and/or operators that can be evaluated to obtain a value. Expressions can be as simple as a single variable or number, or as complex as a combination of variables, numbers, and mathematical operations.
We can simplify the expression by distributing the terms and combining like terms:
E = -2x(1 - 3x) + (2x + 3)(3x - 2)
E = -2x + 6x² + (6x - 4x - 6)
E = 6x² - 4x - 6
Therefore, the simplified expression is 6x²- 4x - 6.

What is 1/4 divided by -1/2?
Answer:
1/2
Step-by-step explanation:
KEEP 1/4 CHANGE the sign to multiplication FLIP 1/2 to 2/1
new equation: 1/4 x 2/1
now we can solve
we do: 1 x 2= 2
so 2 is our nominator
then we do: 4 x 1= 4
so 4 is our denominator
combine the nominator and denominator and we get

Question 1
What value of “n” makes the equation true?
Provide evidence.
-n + 8 = 12
Answer: " n = - 4 " .
__________
Step-by-step explanation:
Given:
-n + 8 = 12 ; solve for "n" ;
Subtract "8" from each side of the equation:
-n + 8 - 8 = 12 - 8 ;
to get:
-n = 4 ;
Which is the same as:
-1n = 4 ;
Divide each side of the equation by "-1" ; to isolate "n" on one side of the equation; and to solve for "n" :
-1n / -1 = 4 / -1 ;
to get:
" n = - 4 " ; which is our answer.
_______________
Now, let's check our answer:
_______________
→ by plugging in our value obtained for "n" ; which is " - 4 " ;
_______________
-(-4) + 8 ≟ 12 ?? ;
_______________
From the "left-hand sign" of the equation:
_______________
" - (-4) = ⁺ 4 " ;
_______________
Note: The opposite of negative value; or the negative of a negative value; is equal to that very positive value.
_______________
⇒ " 4 + 8 ≟ 12 ? ;
⇒ " 12 ≟ 12 ? ; Yes!
_______________
The correct answer is: " n = - 4 " .

Given that f(x)=x^2 + x and g(x) = 3x + 1,
find the value f(g(4))
Answer:
110
Step-by-step explanation:
Given that [tex]f(x)=x^2 + x[/tex] and [tex]g(x) = 3x + 1[/tex] , find f(g(4))
f(g(4)) ==> you always start from the inside (g(4)).
[tex]g(x) = 3x + 1[/tex]
[tex]g(4) = 3(3) + 1[/tex]
[tex]g(4) = 9 + 1[/tex]
[tex]g(4) = 10[/tex]
[tex]f(x)=x^2 + x[/tex]
[tex]f(10)=10^2 + 10[/tex]
[tex]f(10)=100 + 10[/tex]

Claire estimates the her brother is 4 feet tall. When they get measured at the doctor's office her brother's height is 4 feet 2 inches. What was the error, expressed in inches?
Answer: 2 is less than 5 so when she rounded she ended up with 4 feet and the doctors didn’t round
Step-by-step explanation:
I think this is correct
Explanation:
The error is the amount Clair is off by. Both figures involve "4 feet", but the actual measurement has the additional "2 inches" added on. So this is why she is off by 2 inches.

A ball bounces half as far as it did on the preced-
ing bounce and traveled a total distance of 12 feet
on two bounces. How far did it go on the first
bounce?
Answer:
Think proportion and ratio.
The ball bounced twice and travelled 12ft.
The first bounce is twice the distance of the second bounce so the second bounce must be equal to two of the first.
2:1 of a total 12.
You now have three parts 12/3 =4
The first bounce is 2 times this amount which is 8 ft the second bounce was 4 ft as it was only one part.

Alex’s SUV gets an average of only 15 miles per gallon. Gas costs $2.19 per gallon. Write a rule that gives the cost of a trip C when you know the number of miles d that Alex travels.
Answer:
(d miles)/(15 miles/gallon)*($2.19/gallon)
Step-by-step explanation:
Fuel efficiency = 15 miles/gallon.
Gas is $2.19/gallon.
Total cost is y.
miles is d
The equation that provides the total fuel for a trip in Alex's SUV would be:
Fuel for d miles (gallons) = (d miles)/(15 miles/gallon)
This is the total fuel required for a trip of d miles. Multiply this times the cost per gallon to find the total ciost of the trip:
(d miles)/(15 miles/gallon)*($2.19/gallon) = Total cost for a trip of d miles.

A jar contains 125 marbles. Given 2% of the marbles are green, 54% of the marbles are blue, and the rest are red, how many red marbles are in the jar?
there are 55 red marbles in the jar
Answer:
There are 55 red marbles in the jar.
Step-by-step explanation:
Green marbles = 125 x 2/100 = 2.5
Blue marbles = 125 x 54/100 = 67.5
Red marbles = 125 - 67.5 - 2.5 = 55
