Answer:
What are the solutions of the equation 9x4 – 2x2 – 7 = 0? Use u substitution to solve
Step-by-step explanation:
Answer:
50 feet
Step-by-step explanation:
We have to find the perimeter of the fence surrounding the garden.
2l+2w
2(15) + 2(10)
30 + 20
= 50
50 feet will be needed.
By definition, we have to:
In mathematics, the commutative property or commutativity is a fundamental property that has some operations according to which the result of operating two elements does not depend on the order in which they are taken.
This is fulfilled in ordinary addition and multiplication: the order of the addends does not alter the sum, or the order of the factors does not alter the product.
We have then, that the commutative property of the addition is:
3 + (-7) = (-7) + 3
Answer:
An expression that illustrates the commutative property of addition is:
3 + (-7) = (-7) + 3
Sum of interior angles= 180
