Answer:
This is the expression expanded
Step-by-step explanation:
Answer:
The numbers for which the given property hold true are <em>12 </em>and <em>-7</em>
Step-by-step explanation:
Let the number be
.
As per the given statement:
Square of the number (
) is 84 more than five times of the number (
).
Writing in the equation form:

To find:
All the numbers for which above equation holds true.
Solution:

Let us solve the above equation by rearranging the terms and then let us find the roots of the equation.
It is a quadratic equation(i.e. maximum power of
is 2) so it will have 2 solutions i.e. 2 values of
for which the above equation will hold true.

Let us factorize the equation.

So, the numbers for which the given property hold true are <em>12 </em>and <em>-7</em>.
11 +5+11=27in perimeter is adding all the sides together
Answer:
Step-by-step explanation:
To find the missing width/length for the perimeter of a rectangle:
You multiply the found length/width, in this case, the length, by 2. Since there are 2 of the same sides of a rectangle.
6*2 = 12
Now, you have to subtract the perimeter, 26, from the product.
36 - 12 = 24.
You have to divide the difference by 2 because 24 is the 2 missing sides put together.
24/2 = 12
So, the missing width is 12 feet.
