The product of 8 and the sum of 4 and a number is 112. What is the number?
Zigmanuir [339]

Answer:

<h2>8(4 + n) = 112</h2>

Step-by-step explanation:

Let's start by reading the problem since it maybe is a bit confusing at first.

The product of 8

Now we know that it starts with 8 multiplied by another number. We do not know that number yet, so let's put 8 * () and fill in the parentheses later.

So far, our equation is:

8()

.. And the sum of 4 and a number

So, 4 + n

We can enter that into our equation

8(4+n)

The next line says "..Is 112"

So, the solution to our equation is 112

Our equation becomes:

8(4+n)=112

In DEFG, what is DF?
Greeley [361]
First you need to find the X You know that since its a parallelogram opposite sides are congruent so you would do the following equation

(The work below goes vertical)
2x+3=3x-1
-3x-3I-3x-3
---------------
-x      =-4
/-1        /-1
----------------
x= 4

So now that we know x=4 we plug it into the side
4+2=6

Then you multiply is by two since df goes across the whole shape and u get 12

Hope that helps
