A because 16x9=144 and 4x6=24 and 144-24=120
The answer would be A.
When solving a quadratic equation that equals 0, you would look for two numbers that when multiplied equal -30 but added together equal 13. Those numbers would be 15 and 2 (which eliminates B and C). The pair multiplied together has to equal -30 but when added has to equal +13. Meaning the answer would be A. P = -15, P = 2.
I hope this helps!
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.
