Answer:

Step-by-step explanation:

Equation:

x^3 + 7x^2 - 36

Given that:

x1 = -6

x2 = 2

x3 = z

Let the zeros be,

x + 6, x - 2

Multiplying both of these factors ,

(x + 6) × (x - 2)

x^2 + 6x - 2x - 12

= x^2 + 4x - 12

Dividing the polynomial, x^3 + 7x^2 - 36 with the above quadratic equation,

We get:

x^3 + 7x^2 - 36 ÷ x^2 + 4x - 12

= x + 3

z; x + 3 = 0

x = -3

z = -3

-z = 3

blagie [28]

Answer: 3/4 of an hour left.


Step-by-step explanation:

Step 1:  2 hours = 4/4 +4/4

Step 2: 4/4 - 2/4 = 2/4

Step 3: 4/4 - 3/4 = 1/4

Step 4: 2/4 + 1/4= 3/4

Peter uses the equation y = StartFraction 13 over 4 EndFraction x to model the number of miles that he has walked in x hours. Wh
Umnica [9.8K]

The true statement is Peter walks at a rate of 13 over 4 miles per hour.

<h3>What is the true statement?
</h3>

Direct variation is when two variables move in the same direction. If one variable increases, the other variable increases. When the hour Peter walks increases, the distance he walks also increases.

Here are the options:

Peter walks at a rate of StartFraction 4 over 13 EndFraction miles per hour.

Peter walks at a rate of 4 miles per hour.

Peter walks at a rate of StartFraction 13 over 4 EndFraction miles per hour.

Peter walks at a rate of 13 miles per hour.

In 1 and 2, use the table below that shows information about squares.
frutty [35]

1. The table has a constant of proportionality of 4, therefore, the perimeter and side length of squares are proportional.

2. Equation for the proportion is, y = 4x.

Perimeter = 48 cm.

<h3>What is the Equation of a Proportional Relationship?</h3>

The equation that defines a proportional relationship is, y = kx, where k is the constant of proportionality between variables x and y.

1. For the table given:

y = perimeter

x = side length

k = constant of proportionality = 8/2 = 16/4 = 24/6 = 4.

Since k is the same all through, the equation can be modelled as y = 4x, which means the perimeter and side length of squares are proportional.

2. Using the equation, y = 4x,the perimeter (y) of a square when its side length is 12 (x) is:

y = 4(12)

y = 48 cm.

The perimeter (y) of the square is: 48 cm.
