Factoring this expression using the identity of a²-b² = (a+b)(a-b)

Given :-

25 - x²

This can be broken down into:-

... ( 5 )² - ( x )²

In this case, a is 5 and b is x

... ( 5 + x ) ( 5 - x ) Is the answer.

Hope it helps!!

Write the equation of the circle graphed below

Norma-Jean [14]

Answer:

The equation of the circle is

(x + 2)² + (y + 2)² = 9

Centered at (-2, -2), with radius of 3 units.

Step-by-step explanation:

The general equation of a circle is given as

(x - h)² + (y - k)² = r²

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

Looking at the graph, the center is the red dot. It corresponds to -2 on the y-axis, and -2 on the x-axis. So, the center (h, k) is (-2, -2).

The radius is the distance from the center of the circle to the edge of the circle. The red dot is the edge of the circle, there are 3 lines that represent 3 units, so we have a radius of 3 units.

Using these in the general equation, we have

[x - (-2)]² + [y - (-2)]² = 3²

(x + 2)² + (y + 2)² = 9

And this is the equation.

Maggie created this scale drawing of a soccer field, using a scale factor of 1 inch : 12 yards. She wants to make another scale

larisa [96]

The length and width of the new scale drawing is 36 inches and 24 inches respectively.

The given parameters:

Original scale of the soccer field, 1 inch : 12 yards

The original length and width of the soccer field is calculated as follows;

1 inch : 12 yards

original width = 6 x 12 yards = 72 yards
original length = 9 x 12 = 108 yards

For the new scale of 1 inch : 3 yards, the new length and width are represented as;

the new width:

$\frac{1 \ inch}{x} = \frac{3 \ yards}{72 \ yards} \\\\x = 24 \ inches$

the new length:

$\frac{1 \ inch}{x} = \frac{3 \ yards}{108 \ yards} \\\\x = 36\ inches$

Thus, the length and width of the new scale drawing is 36 inches and 24 inches respectively.

Solve for the exact value of x.

blsea [12.9K]

Answer:

$\sqrt{89}$

Step-by-step explanation:

Using the Pythagorean Theorem, if you take 8 and square it, you get 64.

You then take 5 and square it giving you 25.

add the 64 and 25 to get you 89 = x squared.

Then take the square roots of x. (Keep in mind, what you do to one side must be done to the other.)

Because 89 is not a perfect square, you can it it as the square root of 89.
