Factor the equation
please help
Answer:
For A
[tex]{ \rm{6 {x}^{2}(x + 1) - 2x(x + 1) }}[/tex]
• The equation above has a common bracket "(x + 1)". So, let's first factorise out that bracket:
[tex] \dashrightarrow \: { \rm{(x + 1) \{6 {x}^{2} - 2x \} }}[/tex]
• now in the second bracket, the common factor is x and 2.
[tex] \dashrightarrow \: { \rm{(x + 1) \{2x(3x - 1) \}}}[/tex]
• Final answer;
[tex]{ \boxed{ \boxed{ \rm{ \dashrightarrow \: 2x(x + 1)(3x - 1) \: \: }}}}[/tex]
For B
[tex]{ \rm{3(x - 1)(x + 2) + ( {x}^{2} - x)(x + 2) }}[/tex]
• In the equation, the common bracket is (x + 2).
So let's first factorise it out:
[tex] \dashrightarrow \: { \rm{(x + 2) \{3(x - 1) + ( {x}^{2} - x) \}}} \\ \\ { \rm{(x + 2) \{3(x - 1) + x(x - 1) \}}}[/tex]
• In the second major bracket, the common bracket is (x - 1). so factorise it out:
[tex]{ \rm{(x + 2) (x - 1) \{3 + x \}}}[/tex]
• Final answer:
[tex]{ \boxed{ \boxed{ \rm{ \dashrightarrow \: (x + 2)(x + 3)(x - 1) \: \: }}}}[/tex]

x+4=3x+9 how to solve this?
Answer:
x = - [tex]\frac{5}{2}[/tex]
Step-by-step explanation:
x + 4 = 3x + 9 ( subtract x from both sides )
4 = 2x + 9 ( subtract 9 from both sides )
- 5 = 2x ( divide both sides by 2 )
- [tex]\frac{5}{2}[/tex] = x
Oliver drove the first 90 miles of his journey in 1.5 hours and the remaining 120 miles in 3 hours. What was the total average speed. (answer in mph)
Answer:
46 2/3
Step-by-step explanation:
Divide 90 by 1.5 because:
Average Distance= distance/time
then 120 by 3 for same reason
then u find each
then add 90 with 120 to get 210 then divide by 4.5 to get 46 2/3
Answer:
46.6666667
Step-by-step explanation:
we need to know the TOTAL average speed. To do that, we need to know how to get the speed, which is distance/time. Now we have to substitute. The equation we get is: s= (90+120)/(1.5+3). After solving, you should get s= (210miles)/(4.5hrs). Now all we have to do is divide, which equals 46.6666667.
Hope this helps! (:

Total distance from w to z is -10 to 6 = 16
Add the ratios: 2 + 3 + 3 = 8
Divide distance by total ratio: 16/8 = 2
Multiply each ratio by 2 : 2x 2 = 4, 3 x 2 = 6, 3 x 2 = 6
WX is 4 units apart, add 4 to -10 to get x = -6

John has 15 1/4 gallons of gas in his truck. John can drive his truck 7 1/2 miles on each gallon of gas. About how many miles can John drive his truck
Answer:
114 3/8 gallons
Step-by-step explanation:
To solve the question, we multiply by the number of gallons and the amount travelled per gallon:
Let's convert all fractions to improper fractions:
15 1/4 = (15*4 + 1)/4 = 61/4
7 1/2 = (7*2 + 1)/2 = 15/2
Multiply the numerators and the denominators:
61/4 * 15/2 = 61*15/4* 2 = 915/8 = 114 3/8

The difference of two numbers is 4. Their sum is 18. Find the numbers.
Answer:
11 and 7
Step-by-step explanation:
Let these two numbers be x and y where x is greater than y.
We can write two equations from the given information:
x - y = 4
and
x + y = 18
If we add them together, the y's cancel out:
x - y = 4
x + y = 18
2x = 22
x = 11
y is 4 less than x, meaning it is 7.
The two numbers are 11 and 7

Anna pays $5.50 each day to park in a parking deck. How much will she pay for 5 days of parking?
Answer:
27.5 :))
Step-by-step explanation:
so this is the way i did it i breaked it down right so the equation is 5.50 x 5
take away the decimal and now its 550 and i did repeative addition of 5 until i got 2's of 1,100 i added them up then added the 2,200 + 550 without the decimal and i got 2750 instead of adding ',' i took the number 5.50 and saw there were two spaces under the numbers before it got to the decimal and it was two spaces so you do two hops like you do on a line in math so it basically turns to 27.50 :)) but you always take away the 0 if theres no number behind it so it turns to 27.5 :) but if the questions dont have the answer 27.5 then just add the 27.50! its the same number anyways :D ( i hope you understand it!)
Answer:
$27.5
Step-by-step explanation:
All you have to do is 5.50 multiplied by the number of days she is staying their, which is 5. Once you put that in, you get your answer which is 27.5!
