Which of the following is the product of (3x − 5) and (3x + 5)?
A. 9x2 − 25
B. 9x2 − 30x − 25
C. 9x − 10
D. 9x2 + 25
Answer:
Step-by-step explanation:
These binomials make up the difference of squares.
3x * 3x = 9x^2
3x * 5 = 15x
-5 * 3x = - 15x
-5 * 5 = - 25
Notice the 2nd and 3rd terms. They are equal except that one is plus and the other minus. That means they cancel. You are left with
9x^2 - 25

Marina has a bag of lemon watermelon and strawberry candies she is going to choose one candy from the bag the probability of choosing strawberry candy is 1/5 there are 16 lemon candies and eight watermelon candies in the bag how many strawberry candies are in the bag
Answer:
There are 6 strawberry candies in the bag
Step-by-step explanation:
The probability of an event occurring = (The number of required outcome) ÷ (The number of possible outcome)
The given parameters in the question are;
The number of different types of fruit in Marina's bag = 3
The type of fruits in the bag = Lemon, watermelon, strawberry
The probability of choosing strawberry, P = 1/5
The number of lemon candies in the bag = 16
The number of watermelon candies in the bag = 8
Let, 'x', represent the number of strawberry candies in the bag
Therefore, by the definition of probability, we have;
P = 1/5 = x/(x + 16 + 8)
x + 16 + 8 = 5·x
16 + 8 = 5·x - x = 4·x
24 = 4·x
∴ x = 24/4 = 6
The number of strawberry candies in the bag, x = 6 strawberry candies.
Is the ratio 15 : 12 equivalent to 5 : 3 and 10 : 6? Explain.
Answer:
Yes it is
Step-by-step explanation:
When we simplify 15:12, we receive 5:3
Therefore, 5:3 is equvilaent to 15:12
Using this unit ratio, we can solve for other rations
For example, 5:3, the unit ratio, times 2 is 10:6
5 * 2 = 10
3*2 = 6
10, 6 = 10:6

What is the slope and y-intercept for this graph?
(sorry for lots of slope questions I'm still trying to figure it all out :( )
thank you guys
Slope formula:
[tex]\frac{y2 - y1}{x2 - x1}[/tex]
so then take two points : (0,0) and (5,4)
[tex]\frac{4 - 0}{5 - 0} = \frac{4}{5}[/tex]
Answer:
4/5
Answer:
Y-int: (0,0)
Slope: 4/5 or 0.8
Step-by-step explanation:
To find the Y-intercept, look at where the line crosses the y-axis(vertical).To find slope, select two dots from the line and do "rise/run" (rise is up/down while run is left/right)sorry im not rlly good at explaining but yeah

Two of the angles in a triangle measure 21° and 40°. What is the measure of the third angle
Answer: 119°
Step-by-step explanation:
The total of the interior angles of a triangle is 180° so if you add the two angles you have, you get 61 and just subtract that from 180 to get the missing angle.
Can someone teach me how to do this? Please and thank you
Answer:
For the first one, put the input(0) in the place of x. This would make it look like this, 3x0+5
The x is a times sign, which was added when you add the number.
The rest goes like this,

0+5=5
Ouput= 5

Answer: the answer will be (2,4)
Step-by-step explanation:
Step 1: Solve y=3x−2 for y:
y=3x-2
Step 2: Substitute 3x−2 for y in y−2=x:
y−2=x
3x−2−2=x
3x−4=x (Simplify both sides of the equation)
3x−4+−x=x+−x (Add -x to both sides)
2x−4=0
2x−4+4=0+4 (Add 4 to both sides)
2x=4
[tex]\frac{2x}{2} =\frac{4}{2}[/tex] (divide both sides by 2)
x=2
Step 3: Substitute 2 for x in y=3x−2:
y=3x-2
y=(3)(2)-2
y=4 (Simplify both sides of the equation)
Answer:
x=2 , y=4
A symbol CAN’T be used to represent
two different values in the same equation
at the same time. true or false
Answer:
TRUE
Step-by-step explanation:
symbol CAN’T be used to represent two different values in the same equation at the same time.
An equation remains the same if the LHS and the RHS are interchanged.
It is TRUE statement.
An equation is a condition on a variable (or variables) such that two expressions in the variable (variables) have equal value. The value of the variable for which the equation is satisfied is called the solution or root of the equation. An equation remains the same if the LHS and the RHS are interchanged.

Step-by-step explanation:
One stick is 9cm longer than the other 2/5 of the longer stick is equal to 1/2 of the shorter stick. Find the length of the longer stick
Answer:
Length of the longer stick = 45 cm
Step-by-step explanation:
Let the length of shorter stick be x cm
Therefore, length of longer stick = (x + 9) cm
According to the given information:
[tex] \frac{2}{5} (x + 9) = \frac{1}{2} x \\ \\ 2 \times \frac{2}{5} (x + 9) = x \\ \\ 4(x + 9) = 5x \\ \\ 4x + 36 = 5x \\ \\ 36 = 5x - 4x \\ \\ 36 = x \\ \\ x + 9 = 36 + 9 = 45 \\ [/tex]
Length of the longer stick = 45 cm
If $10000 is invested at an interest rate of 10% per year, compounded monthly, find the value of the investment after
Answer:
$10510
Step-by-step explanation:
The question is not complete, here is the correct question
If $10000 is invested at an interest rate of 10% per year, compounded monthly, find the value of the investment after 5 years
Given data
Principal= $10000
interest= 10%
time= 5 years
Required
The final amount
The compound interest formula is
A= P(1+r)^t
substitute
A= 10000(1+0.1)^5
A= 10000(1.01)^5
A= 10000*1.051
A= $10510
Hence the investment will be $10510

1. (i) Is 35 a factor of 455?
(iii) Are 5 and 3 factors of 1647?
(v) Are 2, 3, 5, 7 and 11 factors of 4620?
Answer:
(i) Yes. If you divide it, it gives 13.
(iii) 3 is a factor of 1647 but 5 isn't. If you divide it with 3 first, it gives 549. But if you divide it with 5, it gives 329.4
(v) 2, 3, 5, 7 and 11 are factors of 4620. If you divide it with 2, it gives 2310. If you divide it with 3, it gives 1540. If you divide it with 5, it gives 924. If you divide it with 7, it gives 660. If you divide it with 11, it gives 420.
Step-by-step explanation:
Extra explanation on what a factor is, I don't know how to explain it but here are some examples:
Example:
Find factors of 12
1 x 12 = 12
2 x 6 = 12
3 x 4 = 12
So. 1, 2, 3, 4, 6 and 12 are factors of 12 basically.
