Answer:

Step-by-step explanation:

x + (x+2) + (x+4) + (x+6) + (x+8) + (x+10) = 456

6x + 30 = 456

add -30 to each side

6x = 426

divide each side by 6

x = 71

Complete the steps to simplify (y^4/3•y^2/3)^-1/2. Apply the product of powers property to the expression inside the parentheses

MrRissso [65]

Option A

$\left(y^{\frac{4}{3}} \cdot y^{\frac{2}{3}}\right)^{\frac{-1}{2}} = \left(y^{2}\right)^{\frac{-1}{2}}$

Solution:

Given expression is:

$\left(y^{\frac{4}{3}} \cdot y^{\frac{2}{3}}\right)^{\frac{-1}{2}}$

Product of powers property:

The product of powers property tells us that when you multiply powers with the same base you just have to add the exponents

Which is represented as,

$a^m.a^n = a^{m+n}$

Therefore, the given expression becomes,

$\left(y^{\frac{4}{3}+\frac{2}{3}}\right)^{\frac{-1}{2}}$

Now add the exponents, we get

$\left(y^{\frac{4+2}{3}}\right)^{\frac{-1}{2}}$

Simplify the above expression

$\left(y^{\frac{6}{3}}\right)^{\frac{-1}{2}}$

Simplify the exponent of y, we get

$\left(y^{2}\right)^{\frac{-1}{2}}$

Thus Option A is correct

bulgar [2K]

Answer: (1,-2) , (4,1)

Step-by-step explanation:

Given

The two curves are $y=x^2-4x+1$ and $y=x-3$

From the figure, it observed that the two curves intersect at (1,-2) and (4,1).

So, the ordered pair from least to greatest is (1,-2) and (4,1)

Ano ang area ng isang maliit na parisukat

ankoles [38]

Answer:

Area of square = Side²

Step-by-step explanation:

The area of a 2-D region, form, or flattened lamina in the planes is the quantity that represents its extent. On the 2-D surface or 3-D object, surface is its counterpart. A shape's area can be calculated by comparing it to squares of a specific size.

Area of square = Side²
