Answer:
m
Step-by-step explanation:
Given parameters:
Length of rope = 11m
First length cut off = m
Second length cut off = m
Unknown:
Remaining length = ?
Solution:
Let us find the total length cut off first;
= m +
m
=
= m
So,
Remaining length = 11 -
=
= m
Answer:
<em>The correct answer is the first option</em>
Step-by-step explanation:
<u>Quadratic Equation</u>
The standard form of a quadratic equation is
Sometimes we need to change the expression of the same equation to the form
To accomplish that change, we usually modify the left-hand expression to make it look like the square of a binomial.
The given quadratic equation is
Recall the square of a binomial is
The first term is already present. The second term gives us the value of p:
Solving
Now we need to produce the third term . We only have 41, thus we need to add 8 to both sides of the equation:
