Answer:0.00011726
Step-by-step explanation:
The property in the expression 4 + (x + y) = (4 + x) + y is Commutative property.
<h3>What is the number?</h3>
A number is a mathematical entity that can be used to count, measure, or name things. For example, 1, 2, 56, etc. are the numbers.
It is given that:
4 + (x + y) = (4 + x) + y
As we know,
Commutative property is the property in which we can arrange the terms withouth changing the sign.
For an example:
a + b = b + c
In the given expression
4 + (x + y) = (4 + x) + y
The Commutative property is applied to rearrange the terms.
Thus, the property in the expression 4 + (x + y) = (4 + x) + y is Commutative property.

The surface area of a cylinder can be determined with this formula
sa = surface area of 2 circles + surface area of side
sa = (2 × π × r²) + (2 × π × r × t)
Find the value of r (radius)
r = 1/2 diameter
r = 1/2 × 14.2
r = 7.1 cm
Plug the numbers into the formula
sa = (2 × π × r²) + (2 × π × r × t)
sa = (2 × π × 7.1²) + (2 × π × 7.1 × 12.8)
sa = 100.82π + 181.76π
sa = 282.58π
sa = 282.58 (3.14)
sa = 887.3
The surface area is 887.3 cm². The answer is third option.
Answer:
f(3) = 12
Step-by-step explanation:
f(x) = 2x - 12 + 2x²
f(3) = 2(3) - 12 + 2(3)²
f(3) = 6 - 12 + 2(9)
f(3) = -6 + 18
f(3) = 12
Remember that x=3 is being substituted into the equation, so you can apply this to any function rule problem for any value of x.
