Answer:
(x+3)(x-3)
Step-by-step explanation:
We know that [tex](a+b)(a-b)=a^2+b^2\\[/tex]
So, here we have x² and 9, which can be written as 3².
Therefore, we can have x=a and 3=b
So we get
(x+3)(x-3)
To check that we are correct, we can expand the brackets:
x²-3x+3x-9
=x²-9
hey i need help with how to multiply 8/9 and 1/4. HELP ME OOOUUUUTTTT!!!!!!!!!!!!!!
Explanation:
Multiply the numbers up top: 8*1 = 8
Multiply the numbers in the bottom: 9*4 = 36
The two fractions 8/9 and 1/4 multiply to 8/36. Reduce this to 2/9 after dividing both parts by the GCF 4.
In other words,
8/4 = 2
36/4 = 9
Hello there! :)
When multiplying fractions, we multiply the numerator times the numerator and the denominator times the denominator. We reduce if it's necessary.
So multiply:
[tex]\frac{8}{9} *\frac{1}{4} \\[/tex]
Reduce and get:
[tex]\frac{2}{9} *\frac{1}{1} \\\frac{2}{9}[/tex]
And that's our final answer. Hope it helps you!

Parallelogram A and B are similar. What is the scale factor from rectangle A to B? 12 2 5 А B 4.8
Answer:
i dont get it
Step-by-step explanation:
2w + y = 6
a. Find y if w = -4
b. Find y if w = 10
Answer:
a. Find y if w = -4 --- y = 14
b. Find y if w = 10 --- y = -14
Step-by-step explanation:
This is all about substitution!! For question a, we need to substitute "w" with "-4" ...
2 (-4) + y = 6
We know that a positive time a negative equals a negative...so 2 · -4 is -8.
-8 + y = 6
Now let's add 8 on both sides to isolate the variable...which equals to
y = 14
Onto question b...We substitute w with 10.
2 (10) + y = 6
= 20 + y = 6
Subtract 20 from both sides to isolate "y"
y = -14
Hope this helpsss :D

2x – 1= 7
add 1 to both sides:
2x=8
divide both sides by 2:
x=4
One solution.
A class has 40 students. Number of boys are 6 more than girls. Find number of boys
and girls in the class.
Basically let's represent the number of girls with x.
There are 6 more boys than girls, so x+6
Let's sum it all up
x+x+6=40
Collect like terms;
2x+6=40
2x=40-6
2x= 34
Divide both sides by 2
x=17
17+6=23
Therefore there are 17 girls in the class and 23 boys.

What is the equation in point slope form for a linear function with a slope of m = -4 that passes through the
point (2,- 7)?
Watson and Alva each have the same total number of toy cars and trucks Watson has 4 boxes. Each of his boxes has 7 cars and 2 trucks. Alva
has 2 boxes. Each of his boxes has 11 cars and the same number of trucks
How many trucks are in each of Alva's boxes?
Answer:
Alva has 7 trucks in each box.
Explanation:
You need to determine the total number of toys Watson has. Watson has 4 (7+2) = 4(9) = 36 toys.
Set 36 equal to an expression for the number of toys Alva has. Using t for the number of trucks, 36 = 2 (11+t).Then, solve the equation.
36 = 2(11+t) 36 = 22 + 2t 14 = 2t7 = tSo how many trucks are in each of Alva's boxes?
7 Trucks!The number of trucks that Alva has is 7.
How many trucks does Alva have?A linear function is a function that is made up of a single variable that is raised to the power of one.
The general form of a linear equation is:
y = mx + b
Where:
y = dependent variable b = constant m = independent variableThe first step is to determine the total number of toy cars and trucks that Watson has.
Total number of toy cars and trucks that Watson has = (4 x 7) + (4 x 2)
= 28 + 8 = 36
Since Watson and Alva have the same number of toy cars and trucks, it means that Alva would also have 36 toy cars and trucks.
The equation that represents the total number of toy cars and trucks that Alva has is:
(2 x 11) + (2 x t) = 36
22 + 2t = 36
36 - 22 = 2t
14 = 2t
t = 14 / 2
t= 7

Which equation describes a relationship such that x = 0 must be excluded from the domain?
Answer:
Example: f(x) = (1 + x + x^2) / x, x=0 is excluded from the domain, since division by zero is undefined.
Step-by-step explanation:
The area of a rectangle is x^2-4/2x in.2, and its length is (x + 2)2/2 in. Find the width.
Step-by-step explanation:
the area (length × width) is
A = (x² - 4)/2x in² = (x + 2)(x - 2)/2x
length = (x + 2)²/2 = (x + 2)(x + 2)/2
width = A/length = 2(x+2)(x-2) / 2x(x+2)(x+2) =
= (x-2)/x(x+2) = (x-2)/(x²+2x)
