Using the Associative Property which expression is equivalent to (2+x)+4=

Anna35 [415]

Answer:

x+6

Step-by-step explanation:

The given expression is (2+x)+4.

The associative property is :

(a+b)+c= a+(b+c)

Here,

a = 2, b = x and c = 4

So,

(2+x)+4 = 2+(x+4)

= x+6

So, the equivalent expression is x+6.

Find the distance between the points (13, 20) and (18, 8). 13 7 11

Lana71 [14]

Answer: 13

Step-by-step explanation:

See attached graph.

A third point (18,20) may be added to the two given points to form a right triangle with sides 5 and 12. The distance, x, between the original two points is given by x^2 = 5^2 + 12^2

x^2 = 25 + 144

X^2 = 169

x = 13

Bx-6y=18 and 2x-3y=9

Sloan [31]

X - 6y=18
2x-3y=9 |*-2

x -6y=18
-4x+6y=-18
----------------
-3x=0, x=0

2x-3y=9
2*0-3y=9
-3y=9, y=-9/3, y= -3

Which shows one way to determine the factors of x^3 - 9x^2 + 5x - 45 by grouping ?

adoni [48]

You can group first two conjunctions and second two:
$x^3 - 9x^2 + 5x - 45=(x^3-9x^2)+(5x-45)$ .
In first brackets you have common $x^2$ and in second brackets common is 5:
$(x^3-9x^2)+(5x-45)=x^2(x-9)+5(x-9)=(x-9)(x^2+5)$ .
