Answers

Answer:

(x + 10)(x + 8)

Step-by-step explanation:

Given

x² + 18x + 80

Consider the factors of the constant term (+ 80) which sum to give the coefficient of the x- term (+ 18)

The factors are + 10 and + 8 , since

10 × 8 = + 80 and 10 + 8 = + 18 , then

x² + 18x + 80 = (x + 10)(x + 8) ← in factored form

Did Veronica cut out a right triangle?

Answers

Answer:3.6 + 4.8 > 6

Step-by-step explanation:

The answer is YES, the triangle that is cut down by Veronica is a right triangle.

What is a triangle?

The basic polygonal shape of a triangle has three sides & three interior angles. This is one of the fundamental shapes in geometry and is particularly associated. It has three connected vertices. Triangles can be divided into a variety of categories according to their sides and angles.

As per the given information in the question,

The lengths of the sides of the triangle are given as,

Let Base, b = 3.6 cm

Perpendicular, p = 4.8 cm

Hypotenuse, h = 6 cm

Now, use the equation of Pythagoras' theorem,

h² = p² + b²

6² = 4.8² + 3.6²

36 = 23.04 + 12.96

36 = 36

It satisfies Pythagoras' theorem, which means that it is a right triangle.

Amanda plans on going to the amusement park this Friday. It costs $25.00 to
enter the park, and then $1.25 for every ride that Amanda goes on. What will be
the total cost if Amanda goes on 9 rides?

Answers

Answer:

$36.25

Step-by-step explanation:

To enter the park, Amanda pays 25 dollars.

+$25

It costs 1.25 for every ride that Amanda goes on.

Since we don't know the number of rides Amanda goes on, we will add a variable to represent the number of rides.

1.25x

Then, the passage says that Amanda goes on 9 rides. So, substitute 9 for x.

Equation: 25+1.25(9)

Then solve:

$36.25

A parabola has x-intercepts of (2, 0) and (-4, 0) and has a leading coefficient of 1. What is the equation of the parabola in standard form? *

Answers

9514 1404 393

Answer:

  y = x^2 +2x -8

Step-by-step explanation:

For x-intercepts p and q, factors of the parabola's equation are (x-p) and (x-q). Since the leading coefficient is 1, those are the only factors.

  y = (x -2)(x -(-4))

  y = (x -2)(x +4) = x(x +4) -2(x +4) . . . . use the distributive property

  y = x^2 +4x -2x -8 . . . . use the distributive property again

  y = x^2 +2x -8 . . . . . . . .equation in standard form

The value of y varies jointly with the values of x and z When x = 4 and z = 10, the value of y is 360.
What is the value of y when x 5 and z = 12?
A. 540
B. 9
C. 153
D. 450

Answers

Answer:

A

Step-by-step explanation:

Joint variation is given by:

[tex]y=kxz[/tex]

Where k is some constant.

We are given that y = 360 when x = 4 and z = 10. Therefore:

[tex]360=k(4)(10)[/tex]

Solving for k:

[tex]40k=360\Rightarrow k=9[/tex]

Therefore, our equation is:

[tex]y=9xz[/tex]

Then when x = 5 and z = 12:

[tex]y=9(5)(12)=540[/tex]

The answer is A.
