4a2 - b2
Simplify ————————
2a - b
Trying to factor as a Difference of Squares:
2.1 Factoring: 4a2 - b2
Theory : A difference of two perfect squares, A2 - B2 can be factored into (A+B) • (A-B)
Proof : (A+B) • (A-B) =
A2 - AB + BA - B2 =
A2 - AB + AB - B2 =
A2 - B2
Note : AB = BA is the commutative property of multiplication.
Note : - AB + AB equals zero and is therefore eliminated from the expression.
Check : 4 is the square of 2
Check : a2 is the square of a1
Check : b2 is the square of b1
Factorization is : (2a + b) • (2a - b)
Canceling Out :
2.2 Cancel out (2a - b) which appears on both sides of the fraction line.
Final result :
2a + b

I just says solve
Answer:
x > - 8
Step-by-step explanation:
Given
48 > - 6x
Divide both sides by - 6, reversing the symbol as a result of dividing by a negative quantity.
- 8 < x , thus
x > - 8
Answer:
x >-8
48>−6x
Step 1: Flip the equation.
−6x<48
Step 2: Divide both sides by -6.
[tex]\frac{-6x}{-6}[/tex]< [tex]\frac{48}{-6}[/tex]
x>−8

Catherine bought apples and pears for a school picnic. The total number of pieces of fruit that she bought was less than 100. She bought more apples than pears.
Answer:
it says LESS THAN not less tha n or equal to so it cant be a or b or d, so it is c!
Step-by-step explanation:
Catherine bought apples and pears for the school picnic. If the total fruit is less than 100, then the correct equation for this will be y<100-x and y<x. Hence, option C is correct.
What is an equation?Equations are mathematical expressions that have two algebra on either side of an equal (=) sign. The expressions on the left and right are shown to be equal to one another, demonstrating this relationship. L.H.S. = R.H.S. (left-hand side = right side) is a fundamental simple equation.
As per the given data in the equation,
Catherine bought apple and pears.
The overall quantity is less than 100
Let the number of apples is x and,
The number of pears is y.
She bought more apples than pears,
y<x.
And y < 100-x.

Josh can long-jump 195% of his height with a running start. If Josh is 66 inches tall, how far can he long-jump?
Answer: 128.7 inches
Step-by-step explanation:
Josh's height is 66 inches.
When he jumps with a running start, he can jump as far as 195% of his height.
The length he can jump is therefore 195% multiplied by his height:
= Josh height * 195%
= 66 * 195/100
= 128.7 inches
Answer: 128.7

Find the value of x in the equation below 5= x/6
Answer:
x=30
Step-by-step explanation:
Answer:
x=30
Step-by-step explanation:
To find the value of x in an equation, our goal is always to isolate it so that it's on one side of the equal sign while everything else is on the other. We can do this by performing inverse operations to cancel values out (for example, the inverse operation of addition is subtraction and the inverse operation of division is multiplication).
5=x/6
Because x is being divided by 6, we multiply both sides by 6 to cancel it out on the side with x.
5×6=(x/6)×6
5×6=x
30=x

ASA Congruence Theorem
Suppose both factors in a multiplication problem are multiples of 10. Why might the number of zeroes in the product be different than the total number of zeroes in the factors?
Answer:
Multiplying factors whose products are multiples of 10 add to the number of zeros when factors are multiplied as multiples of 10s.
Step-by-step explanation:
Let the first five multiples of ten be
10*1= 10
10*2= 20
10*3=30
10*4=40
10*5= 50
Suppose we chose 20 and 50.
Now multiplying 20 with 50 we get
20*50= 1000
IF we count the total number of zeros in the factors ( 20 and 50) they are 2.
But the number of zeros in the product (1000) are 3.
This is because when we multiply 2 with 5 we get 10 which adds to the existing number of zeros ( i.e 2) and we get a total of 3 zeros.
And multiplying 10 with 50 we get
10*50= 500
IF we count the total number of zeros in the factors ( 10 and 50) they are 2.
But the number of zeros in the product (500) are also 2.
This is because when we multiply 1 with 5 we get 5 which does not add to the existing number of zeros ( i.e 2) and the total number of zeros remain the same.
Similarly multiplying 20 with 30 we get
20*30= 600
IF we count the total number of zeros in the factors ( 20 and 30) they are 2.
But the number of zeros in the product (600) are also 2.
This is because when we multiply 2 with 3 we get 6 which does not have a zero and the total number of zeros remain the same as in the factors.
So we see that multiplying factors whose products are multiples of 10 add to the number of zeros when factors are multiplied as multiples of 10s.
