To solve this problem you must apply the proccedure shown below:

1. By definition, the opposite sides of a parallelogram are parallel and have equal length.

2. The figure attached shows that the opposite sides with equal length are:

a=c\\b=d

3. Keeping this on mind, you have that the side <em>c</em> and <em>a</em> are equal and measure six centimeters.

4. To find the length of the other sides, you must apply the following formula for calculate the perimeter of a parallelogram:

P=2(a+b)

4. If you solve for <em>b</em>, you will obtain the measure of <em>b </em>and<em> d:</em>

30cm=2(6cm+b)\\30cm=12cm+2b\\b=9cm

Therefore the answer is:

 The lengths of the sides are: 6 cm, 6 cm, 9 cm and 9 cm.

When three times the sum of a number and seven is increased by ten, the result is four. What is the number ?
densk [106]

Answer:

x=9   :))

Step-by-step explanation:

First set up your equation.

"3 times" is multiplication

"THE SUM of A NUMBER and seven" that is parenthesis because of the multiplication before it

"is increased by ten" that is an addition at the end

Now we have 3(x+7)+10=4

Solve your equation!

Distribute the 3 now we have 3x+21+10=4

Add like terms

now it should look like this... 3x+31=4

Subtract 31 from both sides and it looks like...

3x=27

Divide by the x-value

x=9
