Which expression is equivalent to the given expression using the commutative property of addition.​
9966 [12]

The given question is wrong.

Question:

Which expression is equivalent to the given expression using commutative property of addition? 2(x + b) + 3(xa).

Answer:

Option C:

3(xa) + 2(x + b)

Solution:

Given expression is 2(x + b) + 3(xa).

To find the equivalent expression using commutative property of addition.

Let us first define the commutative property of addition.

a + b = b + a

You can add in any order.

Now, write the given expression using commutative property.

2(x + b) + 3(xa) = 3(xa) + 2(x + b)

Option C is the correct answer.

Hence 3(xa) + 2(x + b) equivalent expression using commutative property of addition.

What is the value of c?<br><br><br> units?
ehidna [41]
You may recognize that ∆WYZ is a 3-4-5 right triangle. Without any work, then
  c = 5

_____
If you don't remember that a right triangle with legs 3 and 4 has a hypotenuse of 5, you can compute it using the Pythagorean theorem.
  c² = 3² + 4²
  c² = 9 + 16 = 25
  c = √25 = 5

Determine the solutuon for x^2-3x-28&gt;0
natita [175]

Answer:

 x < -4 or x > 7.

Step-by-step explanation:

We first determine the critical points by solving x^2 - 3x - 28 = 0:

x^2 - 3x - 28 = 0

(x - 7)(x + 4) = 0

x = 7, - 4

so the critical points are  -4 and  7.

Create a Table   (pos = positive and neg = negative):

Value  of           x< - 4        -4  < x < 7         x > 7    

---------------------|----------- |--------------------- |---------------------

x + 4                  NEG           POS                 POS

x - 7                    NEG           NEG                POS

(x + 4)(x - 7)         POS           NEG                POS

So the function is positive (>0) for x < -4 or x > 7.

You can also do this by drawing the graph of the function.

PLEASE MAKE SURE HELP ME!
bulgar [2K]

Answer:

1. The first problem is wrong, it should be 0.5(3(15) + 2(20)) because the parentheses make sure that every purchased item is being divided by 2 (multiplying by 0.5 is the same as dividing by 2)

2. The second problem is partially correct. The first two answers you have checked are correct, but the last one is wrong. The third answer should be 6 + 12 instead because that's just a simplified version of 2(3) + 6(2), meaning they are equal

3. I cannot read your answers in the "Why or Why Not" column in the third problem, but the answers you gave in the "Evaluate" and "Does It Work?" columns are all correct.
