Answer:
<u>Area= 10 </u>
Step-by-step explanation:
<u>Use the equation Base x Height divided by 2 </u>
<u>In this case you would have 5 x 4 divided by 2 which is 10 </u>
Hope this helps!
Answer:
-8a^12b^6
Step-by-step explanation:
multiply each term with the power
Let's call the width 
. Since the length is three more than the width, it is 
.
The area (which we know to be 70) is given by the multiplication of width and length:
To solve this equation, you can use the usual quadratic formula: given an equation 
, the two solutions are
which in your case becomes
So, two solutions are
Since we can't accept a negative length, we only accept the second solution.
So, the dimensions are 7 and 10
If the denominators are not the same, then you have to use equivalent fractions which do have a common denominator . To do this, you need to find the least common multiple (LCM) of the two denominators. To add fractions with unlike denominators, rename the fractions with a common denominator. Then add and simplify.

For example:
1/2 + 1/3
We need to find something called the least common denominator (LCD)... It's really just the LCM of our denominators, 2 and 3.
The LCM of 2 and 3 is 6. So, our LCD 6.
We need to make this our new denominator...
Change the 1/2:
1 x 3 over 2 x 3 = 3/6
Change the 1/3:
1/2 + 1/3 = 3/6 + 2/6
Now we can do it!
(3+2)/6 = 5/6
