Rewrite the equation by completing the square.
x2 + 7x + 12 = 0

Answer:  

I think the answer is -3/4

Step-by-step explanation:

Let x = a number

(2x)(5) = 9x - (3/4)

10x = 9x - (3/4)

Subtract 9x on both sides of equation.

x = -3/4

Answer:

Find two consecutive odd integers whose product is 23 more than their sum. Let x & x+2 be the 2 integers.

Step-by-step explanation:

The value of two consecutive odd positive integers are 5 and 6.

What are Integers?

A whole that can be positive , negative and zero is called integers.

Given that;

The product of two integers is 23 more that their sum.

Let two consecutive odd positive integers are x and x + 2.

Now, By the given condition we can formulate;

x (x + 2) = 23 + x + (x + 2)

x² + 2x = 23 + 2x + 2

x² + 2x = 25 + 2x

x² = 25

Take square root;

x = √25

x = ± 5

Since, Numbers are positive.

So, x = 5

And x + 1 = 5 + 1 = 6

Thus, The value of two consecutive odd positive integers are 5 and 6.

This question is based on the equation of circle. Therefore, the equation of circle is (x - 4)² + (y + 7)² = 81 describes a circle with center (4, -7) and radius 9.

A circle is a closed two-dimensional figure in which the set of all the points in the plane is equidistant from a given point called “centre”. The perimeter around the circle is known as the circumference.

here, we have,

Given:

A circle with center (4, -7) and radius 9.

We need to determined the equation describes a circle with center (4, -7) and radius 9.

According to the question,

As we know that, the equation of a circle in standard form is

⇒ (x - h)² + (y - k)² = r²

Where (h, k) are the coordinates of the center and r is the radius.

Here, it is given that,  (h, k) = (4, - 7) and r = 9.

Therefore, by putting the given values.

We get,

⇒ (x - 4)² + (y - (- 7))² = 9², that is

⇒ (x - 4)² + (y + 7)² = 81 ← equation of circle

Therefore, the equation of circle is  (x - 4)² + (y + 7)² = 81 describes a circle with center (4, -7) and radius 9.

Answer:

Ron paid $ 30 for his pair of jeans, while Tim paid $ 15 for the same model of jeans.

Step-by-step explanation:

Given that Ron paid X dollars for a pair of jeans, and Tim bought the same pair of jeans for half the price as Ron, if they paid a total of $ 45 for the 2 pairs, to determine how much did each spend on their jeans you must perform the following calculation:

X + 1 / 2X = 45

1X + 0.5X = 45

1.5X = 45

X = 45 / 1.5

X = 30

So Ron paid $ 30 for his pair of jeans, while Tim paid $ 15 for the same model of jeans.

Answer:

Step-by-step explanation:

volume = 34cm³

volume = 4/3×π×radius³

34cm³ = 4/3 × 3.14 × radius³

34cm³ = 12.56/3 × radius³

radius³ = 34×3/12.56

radius³ = 8

radius = ³√8

radius = 2cm

diameter = 2×radius

= 2×2

= 4cm
