Answer:
hello
x² + 4 x = 0
x ( x + 2 ) = 0
x = 0 or - 2
Which expression is equivalent to this polynomial?
6x2 + 10x − 56
Given :
[tex]\longrightarrow \sf \qquad {6x}^{2} + 10x - 56[/tex]
⠀
We can write it as,
[tex]\longrightarrow \sf \qquad2 \bigg({3x}^{2} + 5x - 28 \bigg)[/tex]
⠀
We have to find the two numbers a and b such that,
⠀
[tex]\longrightarrow \sf \qquad a + b = 5[/tex]
[tex]\longrightarrow \sf \qquad a b = 84[/tex]
⠀
Obviously, the two numbers are 7 and 12.
[tex]{\longrightarrow \sf \qquad2 \bigg({3x}^{2} - 7x + 12x- 28 \bigg)}[/tex]
[tex]{\longrightarrow \sf \qquad2 \bigg[x \bigg(3x-7 \bigg) +4 \bigg(3x-7\bigg)} \bigg][/tex]
[tex]{\longrightarrow \sf \qquad{2 \bigg(3x - 7 \bigg) \bigg(x + 4\bigg)}}[/tex]
⠀
Therefore,
[tex]{\longrightarrow \bf \qquad{2 \bigg(3x - 7 \bigg) \bigg(x + 4\bigg)} \: is \: equivalent} \bf \: \: to \: \: {6x}^{2} + 10x - 56[/tex]

what is 2{16-[6^2-4(8-2)}=
Answer: 8
Step-by-step explanation:
We have to complete the operation in the parenthesis first. 8-2 is 6. Now we have to take 4(6) which is 24. Now we have 6^2-24. 6^2 is 36. So 36-24 is 12. 16-12 is 4. Now 2 times 4 is 8.

What is the sum of 3 + ( –4 ) ? You may use the number line to help you figure out you’re answer
Answer:
-1
Step-by-step explanation:
To visualize this on a number line you are moving four spots over to the left of 3 (since it is to the left, it is a negative four). 3 to 2 is the first movement to left, 2 to 1 is the 2nd movement, 1 to 0 is the third movement, and 0 to -1 is the fourth movement to the left.
Answer:
-1
Step-by-step explanation:
It's basically 3-4

4. Jose is doing his Algebra homework and comes to a problem that
asks him to solve the equation 5x = 2x. He is unsure whether to divide
both sides by 2x or subtract 2x from each side. Will both methods
lead him to a correct solution or is one method correct and the other
incorrect? Explain your reasoning.
Answer:
x = 0Subtraction methodStep-by-step explanation:
Given equation
5x = 2xSolving for x
5x - 2x = 2x - 2x3x = 03x/3 = 0/3x = 0Let's see what the division method gives
5x = 2x5x/2x = 2x/2x2.5 = 1, which is impossibleNo solution. This method proves to be incorrect.
What is the slope of the line on the graph
Answer:
-2
Step-by-step explanation:
To find the slope, you can do rise (change in y)/run (change in x). Take the points (0, 0) and (3, -6) There is a change of -6 in the y-direction (you can count on the graph) and a change of +3 in the x-direction. Using this, rise/over run, plug in -6/3 to get -2 as the slope.

Find the length of each line segment or object to the nearest half or fours or eighth inch
Answer:
a. [tex]1\frac{1}{8} in.[/tex]
Step-by-step explanation:
hey there,
< There are 8 marks between 1 in. and 2 in. and here we can see that the distance of the line goes only up to the first mark.
Imagine this like a pizza that's divided into 8, but you only took 1 slice. That means you took only [tex]\frac{1}{8}[/tex] of the pizza. It is the same here on the ruler.
It's not only 1/8 though because we also have to add in the first inch. After that inch, we also have 1/8 of an inch. So [tex]1\frac{1}{8}[/tex] in. would be your final answer. >
Hope this helped! Feel free to ask anything else.

Step-by-step explanation:
4 hours, 30 minutes=4.5 hours
4 hours, 45 minutes=4.75 hours

4.5 + 4.75 + 5.5 + 6.25 = 21.00 hours
What is the solution for p in the equation?
1/3p + 1/2p +7 = 7/6p +5+4
Option A. p= 6
Option B. p= -1
Option C. p= -6
Option D. p= 1
Answer:
p=-6
Step-by-step explanation:
the first thing to do is to add all like terms for example [tex]\frac{1}{3}[/tex]p+[tex]\frac{1}{2}[/tex]p would turn into [tex]\frac{2}{6}[/tex]p+[tex]\frac{3}{6}[/tex]p to make it so we can add them together which after we add both of those p's together we get [tex]\frac{5}{6}[/tex]p which now we have [tex]\frac{5}{6}[/tex]p+7=[tex]\frac{7}{6}[/tex]p+5+4 which now we add 5 and 4 which we get 9 which now the equation looks like [tex]\frac{5}{6}[/tex]p+7=[tex]\frac{7}{6}[/tex]p+9 which now we subtract 7 from 9 and we are left with 2 so now the equation is [tex]\frac{5}{6}[/tex]p=[tex]\frac{7}{6}[/tex]p+2 which now we subtract [tex]\frac{7}{6}[/tex]p from [tex]\frac{5}{6}[/tex]p and we are left with -[tex]\frac{2}{6}[/tex]p=2 which now we divide both sides by -[tex]\frac{2}{6}[/tex] which makes the equation look like p=2÷-[tex]\frac{2}{6}[/tex] which equals -6 so all we are left with is p=-6

p=-6

PLEASE HELP ASAP Greg wants to earn more than $50 trimming trees. He charges $6 per hour and pays $4 In equipment fees. What are the possible numbers of hours Greg could trim trees? Use t for the number of hours.
Answer:
Step-by-step explanation:
h = number of hours, e = number of equipment
50 > 6t - 4e
I tried my best
Answer:
Greg could trim trees anywhere more than 7.67 hours for more than $50.
Step-by-step explanation:
First, set up the equation. Since he doesn't have a fixed number of dollars to earn (it is more than $50, not just $50), this would be an inequality.
50 < 6t - 4
50 is the principle goal, 6t because t is hours, and he gets $6 every hour, and - 4 because he pays a one time fee for equiment.
Then, you solve the inequality the way you would with one-variable inequalities:
50 < 6t - 4
46 < 6t
7.67 < t

If F1 has a magnitude of 12 N and the box is stationary, what is the magnitude of F2?
12 N12 N , ,
15 N15 N , ,
6 N6 N , ,
0 N
The magnitude of the Force F2 is; 12 N
How to solve equilibrium of Forces?
According to newton's third law of motion which states that to every action there is an equal and opposite reaction, since F1 has a magnitude of 12N, it means that F2 will be an equal force acting in the opposite direction.
Now, since the force F2 is equal and opposite to F1, then F2 = 12 N
