A. There are two complex roots

B. There is one real, double root

C. There are two real, irrational roots

D. There are two real, rational roots

Answer:

Answer:

B. There is one real, double root

Step-by-step explanation:

For ax² + bx + c = 0, the discriminant is b² − 4ac.

If the discriminant is positive and a perfect square, there are two real, rational roots.

If the discriminant is positive and not a perfect square, there are two real, irrational roots.

If the discriminant is 0, there is one real, double root.

If the discriminant is negative, there are two complex roots.

Here, a = 64, b = -16, and c = 1.

b² − 4ac

= (-16)² − 4(64)(1)

= 0

The discriminant is 0. Therefore, there is one real, double root

Draw a model... write an equation and solve....this is the directions for a 4th grade math homework problem....Help????? At the dog show, there are 4 times as many boxers as spaniels. If there are a total of 30 dogs, how many dogs are spaniels??

Boxers = b

Spaniels = s

Now you have two equations - one that tells you the number of boxers in relation to spaniels and one telling you the number of each breed in relation to the total number of dogs. Solve using substitution.

There are 6 spaniels.

Spaniels = s

Now you have two equations - one that tells you the number of boxers in relation to spaniels and one telling you the number of each breed in relation to the total number of dogs. Solve using substitution.

There are 6 spaniels.

A line passes through (2,−7) and (−3,3) . find the slope-intercept form of the equation of the line. then fill in the value of the slope, m, and the value of the y-intercept, b, below

Slope/m=3-(-7)/-3-2=10/-5=-2

slope/m=-2

y=-2x+b

b= 3=-2*-3+b

b=-3

slope/m=-2

y=-2x+b

b= 3=-2*-3+b

b=-3

True or false all squares have four congruent sides .since rectangles are squares all rectangles have four congruent sides

That is false. A rectangle has two sides that are congruent with each other and another two that are congruent with each other

True: All squares have four congruent sides.

Rectangles are NOT squares.

All squares are rectangles, but not all rectangles are squares.

This is because squares are a certain type of rectangle.

Rectangles are not a certain type of square.
