expressions. What do the rewritten expressions
tell you about the relationships among the
quantities? ​

Answers

Answer:

12(x + 8)  8(x + 12)  and x( 12 + 8) all equal to 20x

Step-by-step explanation:

Three equivalent expressions of 12x + 8 are, 2(6x + 4), 4(3x + 2) and

8 + 12x.

What are GCF and distributive property?

The GCF of two or more than two numbers is the highest number that divides the given two numbers completely.

We also know that distributive property states a(b + c) = ab + ac.

Given, An expression 12x + 8.

Now, The first way of writing an equivalent expression to 12x + 8 is,

2(6x + 4).

The second one is,

4(3x + 2).

We can also write an equivalent expression for 12x + 8 by the commutative law of addition (a + b) = (b + a).

Answers

Answer:Yes that is correct, 3(2t + d) is equal to 6t+3d. This is due to the distributive property of multiplication, or as I like to call it, the DPM. The DPM works for all multiplication and praentheses problems. For example, 7(2t+3d)=14t+21d. You multiply the coefficient of the whole parentheses by each number/variable in the equation. Another example is 5(n+s)=5n+5s.

Write a function rule for the output is 3 greater than 5 times the input.Use x for the independent variable and y for the independent variable

Answers

Answer:

hello sup

Step-by-step explanation:

Answer:
y = 6+3x
Step-by-step explanation:
If y = f(x), it means y is depending on x. This shows that y is the independent variable and x is the dependent variable.
y variable will be the output depending on the input variable x.
According to the function rule, “The output is 6 greater than three times the input." This can be expressed mathematically as 3x+6 (x being the input)
Three times the input = 3x
6 greater than three times the input = 6+3x
Since y is output then;
y = 6+3x
