How do i simplify 2u-6u

Answer:

TWO CRACKERS

Step-by-step explanation:

I'm assuming they want to find x. Here we see that these two are similar triangles, so the sides are reflective. 5x/5 should be equal to 4/x, so 5x/5 = 4/x. If we use cross multiplying we get 5x^2 = 20. divide both sides by 5 and we get x^2 = 4 or x = 2.

Hope this helped

Answer:

The sum of their ages is 29, which we can express as the equation:

P + (P - 11) = 29

Simplifying the equation:

2P - 11 = 29

Adding 11 to both sides:

2P = 40

Dividing both sides by 2:

P = 20

Therefore, Pete's age, represented by "P," is 20 years old.

1. Find the graph of the parabola attached below

2. Vertex (-4, 2)   Focus (-7/2, 2)  Directrix (x = -9/2)  Endpoints (-7/2, 1) (-7/2, 3)

For the parabola,  x = 1/2(y-2)² - 4 we will use the equation x = 4p(y-k)² + h,

Vertex → (h, k)

In our given equation, (y - 2) → (y - k), so k = 2. The term on the rightmost side of our equation (-4) → h in the form, so we know h = -4. ∴  vertex (-4, 2).

focus → (h, k) = (-4, 2); P = 1/2

Parabola is symmetric around the x axis and so the focus lies a distance P, from the center, along the x axis.

∴  Focus is (-4 + p, 2)

(-4 + 1/2, 2) ⇒ (-7/2, 2)

directrix → x = d

Parabola is symmetric around the x axis and therefore the directrix is a line paralled to the y axis a distance away from the ceter (-4, 2) x coordinate.

∴ x = -4 - p   ⇒ x = -4 - 1/2

x = 9/2

focal chord endpoints →

The focus of the parabola is (-7/2, 2).

The y-coordinate of the focus is 2, so the y-coordinates of the endpoints of the focal chord are 2 + 1 and 2 - 1, → 3 and 1.

Therefore, the endpoints of the focal chord are:

(-7/2, 3) and (-7/2, 1).

The pattern is formed by adding 4 tiles to the previous cross.

In the first cross, there is 1 tile on each arm. In the second cross, there are 5 tiles on each arm, which is 4 more than the first cross. In the third cross, there are 9 tiles on each arm, which is 4 more than the second cross. And so on.

The following formula can be used to calculate the number of tiles in the nth cross:

tiles = 4 × (n - 1) + 1

The maximum area Wayne can enclose for Vayla's bunnies is 126.5625 square feet.

The perimeter of a rectangle is given by the formula: P = 2L + 2W.

In this case, the perimeter is given as 45 feet: 2L + 2W = 45.

Rearranging the equation for the perimeter, we have: 2L = 45 - 2W.

Solving for L, we get: L = (45 - 2W)/2 = 22.5 - W.

Now, we can express the area A in terms of W:

A = L x W = (22.5 - W) x W.

To find the maximum area, we take the derivative of the area with respect to W and set it equal to zero:

dA/dW = 22.5 - 2W = 0.

22.5 - 2W = 0

2W = 22.5

W = 22.5/2

W = 11.25.

and, L = 22.5 - W

L = 22.5 - 11.25

L = 11.25.

Therefore, the dimensions of the rectangle that will maximize the area with 45 feet of fencing are L = 11.25 feet and W = 11.25 feet.

Finally, we can calculate the maximum area:

A = L x W

A = 11.25 x 11.25

A = 126.5625 square feet.

Thus, the maximum area Wayne can enclose for Vayla's bunnies is 126.5625 square feet.

Rounding to the nearest tenth of a centimeter, the slant height is approximately 43.1 centimeters.

The lateral area of a cone is given by the formula L = πrs, where L is the lateral area, r is the radius, and s is the slant height.

We are given that the lateral area L is equal to 612π m², and the radius r is 14.2 cm (0.142 m).

We can rearrange the formula to solve for the slant height s:

L = πrs

612π = π × 14.2 × s

Dividing both sides by π and 14.2:

612 = s × 14.2

Now, solve for s:

s = 612 / 14.2

s ≈ 43.0986

L = rs, where L is the lateral area, r is the radius, and s is the slant height, gives the lateral area of a cone.

We are informed that the radius r is 14.2 cm (0.142 m), and the lateral area L is equivalent to 612 m2.

To solve for the slant height s, we may rewrite the formula as follows:

L = πrs 612π = π × 14.2 × s

612 = s 14.2 after dividing both sides by and 14.2

The sum f(x) + g(x) is (x³ + 16x² + 6x - 99) / (x²-9)(x² + 3x) and the type of discontinuity for f(x) at x = ±3 is a removable discontinuity, and for g(x) at x = 0, it is an infinite discontinuity or vertical asymptote.

To find f(x) + g(x), we need to add the two functions together:

f(x) + g(x) = (x+2)/(x²-9) + 11/(x²+3x)

To add these fractions, we need a common denominator.

The common denominator in this case is (x² - 9)(x² + 3x), which is the product of the denominators.

Rewriting the fractions with the common denominator, we have:

f(x) + g(x) = [(x+2)(x² + 3x)]/[(x²-9)(x² + 3x)] + [11(x²-9)]/[(x²-9)(x² + 3x)]

Combining the fractions, we have:

f(x) + g(x) = [(x+2)(x² + 3x) + 11(x²-9)]/[(x²-9)(x² + 3x)]

Simplifying the numerator:

[(x+2)(x² + 3x) + 11(x²-9)] = (x³ + 5x² + 6x + 11x² - 99)

= (x³ + 16x² + 6x - 99)

Therefore, the sum f(x) + g(x) is (x³ + 16x² + 6x - 99) / (x²-9)(x² + 3x).

The excluded values for the function f(x) are x = ±3, and for the function g(x), the excluded value is x = 0.

The type of discontinuity for f(x) at x = ±3 is a removable discontinuity, and for g(x) at x = 0, it is an infinite discontinuity or vertical asymptote.
