For example a × b × c = c × a × b
Answer:
Therefore the Commutative Expression is,
11 × w × 3 = 11 × 3 × w
Step-by-step explanation:
Commutative property:
The Commutative property states that order does not matter.
This property allows Two or more factors to be multiplied in any order without Changing the product.
Multiplication and addition are commutative.
For example a × b = b × a
1. 2 × 5 = 5 × 2
Therefore the Commutative Expression is,
11 × w × 3 = 11 × 3 × w
Answer:
A 21/4
Step-by-step explanation:
When forming a perfect square trinomial you need to "complete the square".
All of the steps to completing the square when solving an equation:
1. The leading coefficient must be 1.
2. Divide b by 2.
3. Square (b/2)
4. Add (b/2)^2 to both sides to keep the polynomial balanced.
5. You can now write the perfect square trinomial and solve.
x^2 - 3x
-3/2
(-3/2)^2 = 9/4 = 2 1/4
Answer:
The answer is 3+(-6) = -9, because -9 is 6 units to the left of 3.
Answer:
<h3>y = 1</h3>
Step-by-step explanation:
Correct question
The points ( 2,4) and (5,y) lie on the same line. If the slope of the line is --1, what is the value of y
The formula for calculating slope of a line is expressed as;
m = y2-y1/x2-x1
Substitute the given point
y - 4/5-2 = -1
y-4/3 = -1
y-4 = -3
y = -3+4
y = 1
Hence the value of y is 1
Part A:The original brand was 12$ each and the new one is 8$ each.
12-8=4
Part B:she will save 16$ each month because y=12*4 and y=8*4 is 16$
