Answer:

D: PQ is congruent to QR

Step-by-step explanation:

In a rectangle, there are a few statements that are always true. Opposite sides are congruent and parallel and all angles meet at 90 degrees. However, adjacent sides (sides that are touching/share a vertex) are not necessarily congruent. They can be; if they are then that rectangle is a square. Nevertheless, if adjacent sides are not congruent, then it is still a rectangle, so long as they meet at a right angle.

Solve for x: -5/6x= -10/3 x=?

k0ka [10]

Answer:

Solve for x: -5/6x= -10/3 x=?

x = 1/4

Step-by-step explanation:

from the equation ,Solve for x: -5/6x= -10/3 , to solve for x we will first cross multiply

we have; -15= -60x

divide both sides by -60

-15/-60 = -60x/-60

x = 15/60 ( the minus will cancel out)

x = 1/4

check for your answer by putting 1/4 where you see x

i.e -5/6(1/4) = -10/3

-5 × 2/3 = -10/3

-10/3 = -10/3......... proved!!

What is the 38th term of 459,450,441,..

galina1969 [7]

Answer:

The 38th term of 459,450,441,.. will be:

$a_{13}=351$

Step-by-step explanation:

Given the sequence

$459,450,441,..$

An arithmetic sequence has a constant difference 'd' and is defined by

$a_n=a_1+\left(n-1\right)d$

computing the differences of all the adjacent terms

$450-459=-9,\:\quad \:441-450=-9$

so

$d=-9$

The first element of the sequence is

$a_1=459$

so the nth term will be

$a_n=-9\left(n-1\right)+459$

$a_n=-9n+468$

Putting n=38 to find the 38th term

$a_n=-9n+468$

$a_{13}=-9\left(13\right)+468$

$a_{13}=-117+468$

$a_{13}=351$

Therefore, the 38th term of 459,450,441,.. will be:

$a_{13}=351$
