Answer:
-9/10 =r
Step-by-step explanation:
7/10=r-(-8/5)
Subtracting a negative is like adding
7/10=r+(8/5)
Subtract 8/5 from each side
7/10 - 8/5=r+(8/5) - 8/5
7/10 - 8/5 = r
Get a common denominator
7/10 - 16/10 = r
-9/10 =r
we have
Find the roots
Equate the function to zero
Group terms that contain the same variable, and move the constant to the opposite side of the equation
Complete the square. Remember to balance the equation by adding the same constants to each side.
Rewrite as perfect squares
Square root both sides
therefore
<u>the answer is</u>
It would be 75 units in length and 18 units in width.
B = 18 because 67 - 49 = -18
-18 =-b
Divide by negative 1 because you can't have a negative variable in your answer.
