The solutions for the given equation are x = -1 and x = 3/4. Using the quadratic formula, the solutions for the given equation are calculated.
<h3>What is the quadratic formula?</h3>
The formula which is used to calculate the roots(solutions) of the quadratic equation in the form is
x = [- b ± ]/2a
<h3>Calculation:</h3>
The given equation is
In comparison with the standard form of quadratic equation ,
we get, a = 4, b = 1 and c = -3
So, solving the given equation using the quadratic formula,
x = [- b ± ]/2a
= [- 1 ± ]/2(4)
= [-1 ± ]/8
= (-1 ± 7)/8
Thus, x = (-1 + 7)/8 = 3/4 and x = (-1-7)/8 = -8/8 = -1
Therefore, the solutions of the given equation are x = -1 and x = 3/4.

Answer: 60
Step-by-step explanation:
You have to use Pythagorean Theorem because the other side is not listed of the triangle
Pythagorean Theorem: a² + b² = c²
a² + 20² = 25²
a² + 400 = 625
625-400 = a²
a² = 225
Find the square root of 225 to find the missing length
= 15 (this is the missing length for QS
To find the perimeter, add all the sides...
15 + 20 +25 = 60
Answer:
gabby is correct
Step-by-step explanation:
Answer:
r = 94
Step-by-step explanation:
Solve the equation by isolate the variable, r. Note the equal sign, what you do to one side, you do to the other. Add 26 to both sides:
r - 26 (+26) = 68 (+26)
r = 68 + 26
Add:
r = 94
r = 94 is your answer.
