Answer:Equation at the end of step 1
STEP
2
:
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
Step-by-step explanation:
You need to use the equation Distance (miles)=Rate (miles/hour) x Time (hours)
Brandi: 2.5 miles=rate (1/2 hour) r=5 miles per hour
Sharna=3.5 miles= rate (3/4 hour) r = 7 miles per hour.
Therefore brandi jogged at a slower rate.
Answer:
5
Step-by-step explanation:
when the question asks for evaluate, always substitute the expression with the values given.
So, her x = -3 and y=4
So we find 1/2 of 2x - y
This is also half of -6-4 = -half of -10 = 5
Hope this helps,
Good Luck
If you are looking for an expression it would be x < 4 and the < has a line underneath for less than or equal to. If this is right could I possibly have brainliest? Hope this helped!! :)
Answer:
The independent variable is the number of weeks
The dependent variable is the number of website she makes
N = 3w
Step-by-step explanation:
Number of website per week = 3
The independent variable is the number of weeks
The dependent variable is the number of website she makes
Let number of websites she can design when given any number of weeks = N
N = 3 * w
N = 3w
Where,
w = number of weeks
The equation is N = 3w
