Step-by-step explanation:
since x is squared, you would put that into both parenthesis, so you should have (x)(x) right now
then you need to find factors of 40 that add to 14
factors of 40: 40 and 1, 20, and 2, 4 and 10, 5 and 8
4 and 10 multiply to equal 40 and add to equal 14
put each factor into a parenthesis
so now you should have (x+10) (x+4)
side note: if the number 40 was negative then one of the factors would have to be negative, this would result in (x+10) (x-4) or (x-10) (x+4)

Answer:
b) -12 , -8 , -4, 0
Step-by-step explanation:
-12 + 4(n - 1)
n means the term
place the values of 1, 2, 3 and 4
-12 + 4(1-1) = -12
-12 + 4(2-1) = -8
-12 + 4(3-1) = -4
-12 + 4(4-1) = 0
hence the answer is
b) -12 , -8 , -4, 0

Fifteen more than a number is written as...?
Answer:
x + 15
Step-by-step explanation:
Since I don't know what this number is, I'm going to use the variable x to substitute for the value of the unknown number.
So it would just be x + 15 because addition is the operation of adding and the key words are usually more. Since one of the numbers is unknown, we can't get an answer like "100" because x is undefined.
Say x=100, then the number would be written as 115 in it's simplest form but you could also write it as 100+15. So I'm just using substitution.
Answer:
x+15
Step-by-step explanation:
Since it says "than a number"
What number is it?
We don't know.
We will say thats a variable.
What variable?
Well it really can be anything. ONLY LETTERS
Lets do a x
Now the problem changed.
Fifteen more than x is written as...?
It says "more"
You use plus.
Now the problem changed.
Since is written as... is your answer so yeah
15+x is the problem.
There you go the answer!
People writes the variable first so:
x+15
The answer is x+15

Solve for v
7 - V = 3
Answer:
7 - V = 3
take away 7 from both sides
-V = -4
V = 4
Step-by-step explanation:
Hey there!
7 - v = 3
-v + 7 = 3
SUBTRACT 7 to BOTH SIDES
-v + 7 - 7 = 3 - 7
SIMPLIFY IT!
-v = 3 - 7
-v = -4
DIVIDE -1 to BOTH SIDES
-v/-1 = -4/-1
SIMPLIFY IT!
v = -4/-1
v = 4/1
v = 4
Therefore, your answer is: v = 4
Good luck on your assignment & enjoy your day!

what is this?!?!? Need an answer in 24hrs please.
Answer:
X
Step-by-step explanation:
To be a function, the line has to pass the vertical line test. This means that when a vertical line is passed through every x value, it will only cross the graphed line once.
To help: draw vertical lines through each graph.
In graph W: the line would pass through the top and bottom of the circle - not a function
In graph X: the line passes once through every area - a function
In graph Y: the line passes through the top curve as well as the bottom curve - not a function
In graph Z: the line passes through the curves multiple times - not a function
-2 (k - 9)= -6
What’s the answer
Answer:
12
Step-by-step explanation:
distribute equation
-2 times k = -2k
-2 times -9 = 18
so -2k+18=-6
solve
subtract 18 from both sides
-2k= -24
divide -2 from both sides
k =12
Answer:
k=12
Step-by-step explanation:
-2(k-9)=-6
divide both sides
k-9=3
move the k to the right
k=3+9
add 3+9
k=12

Find the value of X in the triangle shown below.
Answer:
50
Step-by-step explanation:
The sum of a triangle's angles are 180 so since you know one angle is 80, you would put 2x + 80 = 180, which would be 2x = 100, which simplifies to x = 50
A blueprint for a house states that 2 inches represents 8 feet. If the width of a window is 2.5 inches on the blueprint, what is the width of the actual window?
Answer:
10 feet. You can prove this by dividing 8 by 2, with this you find that 1 inch on the blueprint is equal to 4 feet. then take half of 4(2), and add it to 8 to get your answer.

3/4=m+1/4
What is m
Answer:
m = 1/2
Step-by-step explanation:
We need to solve the equation:
3/4 = m + 1/4
In order to solve for m, we must isolate the variable - in other words, we need to move all the m terms to one side and all the non-m terms to the other.
So, subtract 1/4 from both sides to isolate m:
3/4 - 1/4 = m
m = 2/4 = 1/2
Thus, m = 1/2.
