Answer:

6x = 42

Step-by-step explanation:

The formula to find the area of a rectangle is A = LxW. Since we have a value for the width, we simply need to find what to multiply to 6 to get 42.

Let x = length

6x = 42

We then divide both sides by 6 to find the value of x.

\dfrac{6x}{6}=\dfrac{42}{6}

x=7

So we know the length is 7.

To check the answer we substitute x with 7.

6(7)=42

42=42

If B = { p : p is a factor of 12 } list the elements of this set and find n ( B )​
anastassius [24]

Answer:

B={1,2,3,4,6and12}

n (B) =6

Step-by-step explanation:

<h3>Greetings !</h3>

Factor, in mathematics, a number or algebraic expression that divides another number or expression evenly—i.e., with no remainder. For example, 3 and 6 are factors of 12 because 12 ÷ 3 = 4 exactly and 12 ÷ 6 = 2 exactly. The other factors of 12 are 1, 2, 4, and 12.

Hope it helps!
