Answer:

A. Rectangle

Step-by-step explanation:

Shown in the attachment are the four points graphed on a coordinate plane.

We can see that the opposite sides are parallel to each other and have the same length.

The answer cannot be B. Square because the side lengths of this quadrilateral are not all equal to each other.

The answer cannot be C. Rhombus because of the same reason as above.

The answer cannot be D. Trapezoid because the bases of the quadrilateral are not of different lengths.

Therefore, the answer must be A. Rectangle since the angles are 90° angles, and the opposite sides are parallel and equal.

Explain how to write x^2+5x+6 as the product of two linear factors. Use complete English and math sentences.

Answers

Answer:

(x + 3)(x + 2)

Step-by-step explanation:

Given

x² + 5x + 6

Consider the factors of the constant term (+ 6) which sum to give the coefficient of the x- term (+ 5)

The factors are + 3 and + 2 , since

3 × 2 = + 6 and + 3 + 2 = + 5 , then

x² + 5x + 6 = (x + 3)(x + 2) ← in factored form

Steve started with $250 and spent $20 per week. Chelsea started with nothing but saved $30 per week. Use x for time and y for savings.

Write an equation to represent Steve's situation.

Answers

Answer:

[tex]250 - 20x=y[/tex]

Step-by-step explanation:

As per the given problem, Steve starts with $250, and spent $20 a week, the problem mentions nothing about Steve's savings, therefore, one can assume that they didn't save anything. As the problem requests, parameter ([tex]x[/tex]) will be used for the time, and ([tex]y[/tex]) for the savings.

Steve's saving would be equal to his initial value, minus his expense, in essence;

[tex]250 - 20x=y[/tex]

The initial value, minus the amount spend per week multiplied by the week number will equal the savings left.

Answer:

y=250-(20x)

Answer:

A) 6 square meters

Step-by-step explanation:

To find the area of a triangle you must multiple the base and the height, but in this question the base isn't given. Using the Pythagorean theorem to find the base you get 4 as the base. Now you multiply 3 and 4 to get 12 (square area), then divide it by two and get 6 (triangle area)

Steps:

b^2 = 5^2 - 3^2

b^2 = 16

[tex]\sqrt{b} = 4[/tex]

3*4 = 12

12/2 = 6 square meters
