Alborosie

Following are the calculation to<u> find the value of x</u>:

Given:

$\to 4(6x-9. 5)=46\\$

To find:

x=?

Solution:

$\to 4(6x-9. 5)=46\\\\\to 24x- 38.0=46\\\\\to 24x =46-38\\\\\to 24x= 8\\\\\to x= \frac{8}{24}\\\\\to x= \frac{1}{3}\\\\$

Therefore, the final answer is " $\bold{\frac{1}{3}}$ ".

Prove this conjecture

steposvetlana [31]

Answer:

See explanation

Step-by-step explanation:

Consider the natural number $n(n+1)(n+2).$

If $n$ is the natural number, then $n+1, \ n+2$ are next two natural numbers, so numbers $n,\ n+1$ and $n+2$ are three consecutive numbers.

Given three consecutive natural numbers, one of them is always even number and one of them is always multiple of 3, so the product

$n(n+1)(n+2)$

is divisible by 6.

Polygon q is a scaled copy of polygon p using a scale factor of 1/2 polygon q’s area is what fraction of polygon p’s area?

san4es73 [151]

Answer:

Polygon q’s area is one fourth of polygon p’s area

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its areas is equal to the scale factor squared

Let

z-----> the scale factor

x-----> polygon q’s area

y-----> polygon p’s area

$z^{2} =\frac{x}{y}$

In this problem we have

$z=\frac{1}{2}$

substitute

$(\frac{1}{2})^{2} =\frac{x}{y}$

$(\frac{1}{4}) =\frac{x}{y}$

$x=\frac{1}{4}y$

therefore

Polygon q’s area is one fourth of polygon p’s area
