Answer: 75 feet per hour
Step-by-step explanation:
X: 1, 3
Y: 200, 350
150/2
75
X^2 +3x-4=0
(X+4)(x-1)=0 so x = -4 and x=1 are solutions
Answer:
72 1/4
step-by-step explanation:
The constant should be added to form a perfect square trinomial will be 1/4. Then the correct option is D.
<h3>What is a quadratic equation?</h3>
It's a polynomial with a value of zero. There exist polynomials of variable power 2, 1, and 0 terms. A quadratic equation is an equation with one statement in which the degree of the parameter is a maximum of 2.
The expression is x² + x.
Then the constant should be added to form a perfect square trinomial.
Then the constant will be
The square of the half of the coefficient of the variable x is to be added to make a perfect square.
Then the constant will be 1/4.
Then the perfect square will be
