25x-10=40 solve for x
Actual roots of f(x)=2x^2+2x-24
[tex]f(x) = 2 {x}^{2} + 2x - 24 [/tex]
[tex]f(x) = 2( {x}^{2} + x - 12) [/tex]
[tex]0 = 2( {x}^{2} + x - 12)[/tex]
Divided sides by 2
[tex] {x}^{2} + x - 12 = 0 [/tex]
[tex](x + 4)(x - 3) = 0[/tex]
_________________________________
[tex]x + 4 = 0[/tex]
[tex]x = - 4[/tex]
_________________________________
[tex]x - 3 = 0[/tex]
[tex]x = 3[/tex]
Thus the actual roots are -4 and 3.....
And we're done.

Answer:
x= 3, -4
Step-by-step explanation:
Set 2 x ² + 2 x − 24 equal to 0 .
2 x ² + 2 x − 24 = 0
Solve for x .
Factor the left side of the equation.
2 ( x² + x − 12 ) = 0
Factor
x ² + x − 12 using the AC method.
2 ( x − 3 ) ( x + 4 ) = 0
If any individual factor on the left side of the equation is equal to 0 , the entire expression will be equal to 0 .
x − 3 = 0
x + 4 = 0
Add 3 and subtract 4 to both sides of the equation.
x = 3
x = -4
The perimeter of a rectangle is 42 inches. If the width of the rectangle is 6 inches, what is the length?
OA
12 inches
OB. 15 inches
OC 21 inches
OD. 40 inches
Answer:
Option B: 15 inches
Step-by-step explanation:
p=2w+2l so 12 (2*6) +2x= 42
42-12=30
30/2=15
Lana uses factoring by grouping to factor the polynomial 8x2y−10xy2+12x−15y. Her work follows, but the last two lines of work are missing.
Which answers correctly fill in the blanks?
Select two answers: one for blank 1 and one for blank 2.
Answer:
Blank 1: 2xy(4x-5)=3(4x-5)
Blank 2: (2xy+3)(4x-5)
Step-by-step explanation:
The first step in factoring this polynomial is to find the biggest common factor in both numbers inside the parenthesis, and the second step is to find the biggest common factor of the 2 addents.
The other steps are invalid, either because they don't respect positive or negative signs, or that they just factor it wrong completely.
The only correct answer are:
Blank 1: 2xy(4x-5)=3(4x-5)
Blank 2: (2xy+3)(4x-5)

Raleigh went to a gaming arcade for his birthday. His parent gave him $55 to spend. He purchased $14.25 in food and drinks, and put the rest of the money on the gaming arcade. Each Game in the arcade cost $1.25. Write a linear inequality to represent how many games g Raleigh can play in the arcade
Answer:
Step-by-step explanation:
Let [tex]g[/tex] denotes number of games that Raleigh can play in the arcade.
Cost of 1 game = $1.25
Cost of [tex]g[/tex] games = [tex]\$1.25g[/tex]
Amount spent in food and drinks = $14.25
Total amount spent by Raleigh = [tex]14.25+1.25g[/tex]
Also, amount with Raleigh = $55
So, the inequality is [tex]14.25+1.25g\leq 55[/tex]
Divide the inequality by 5
[tex]2.85+0.25g\leq 11[/tex][tex]2.85+0.25g\leq 11[/tex]

Solve for v.
- 13 = 7+5v
Answer:
Step-by-step explanation:
- 13 = 7+5v
subtract 7 on both sides to cancel out 7
- 20 = 5v
divide both sides by 5 to isolate v
- 4 = v, v is negative because negative divided by a positive will make your answer stay negative
W = A/L
(solve for A)
A = W +L
A = W-L
A = W/L
A = LW
Answer:
A = LW
Step-by-step explanation:
A/L =W
A =WL
therefore, A = LW

Which is simplified form of the expression (6-2•65)-3
Answer:Answer:
The simplified form of this is 6^-9
Step-by-step explatnation
In order to find this, we first complete the operation inside the parenthesis. In this case, since it is multiplication, we add the exponents.
6^-2 x 6^5 = 6^3
Now that we have the simplified inside we multiply exponents using the parenthesis.
(6^3)^-3 = 6^-9

Answer:
5) y = -8x -4
6) y = 2x + 3
Step-by-step explanation:
Slope is rise over run. For the first problem, you went down 8 and over 1 to your next point. Going down means you have a negative slope. -8/1 is 8. Your y intercept is where the line meets the y axis. The line meets the y axis at -4.
The line meets a new point every time it goes over 1 and up 2. Rise over run means 2/1. The line goes up so the slope is positive. The line meets the y axis at 3

Answer:
you eould have to start with 4 times 6 welll use algabra
Step-by-step explanation:
Part A: What are the missing numbers in the table? Show your work. (4 points)
Part B: Harry also does part-time yard work. The ratio of the number of hours Harry works in the yard to the money he earns in dollars is 1:10. Create a table to show the money earned by Harry for 5, 6, and 8 hours of work in the yard. (3 points)
Part C: How many more dollars does Harry earn working as a babysitter for 5 hours than doing yard work for 5 hours? Show your work. (3 points)
Part A: The Numbers of Hours and Money earned are being divided by 6 , to solve you need to multiply and divide the numbers by 6 therefore it's 48, and 11.
Part B: Just like Part A Multiplying 6 but this time 7. |5 x 7 = 35| 6 x 7 = 42| 8 x 7 = 56. (I think lol)
Part C: Collins Makes $5 more when working for 5 hours.
