2( x + y ) = 6|\div 2\\ x+y=3|\cdot3\\ 3x+3y=9\implies \text{D}\\

\bf 2(x+y)=6\implies (x+y)=\cfrac{6}{2}\implies \boxed{(x+y)=3} \\\\\\ 3x+3y\implies 2x+x+2y+y\implies (x+y)+(2x+2y) \\\\\\ \stackrel{3}{(x+y)}+\stackrel{6}{2(x+y)}\implies 3+6\implies 9

Associative property of (21)(7)(3x) ? <br> PLEASE HELPPPP <br> 40 PTS!!!!
sdas [7]
Ehh, now it's letting me answer.

So the associative property is basically as long as it's addition or multiplication,  you can move around the groupings and it will still be the same.

For example, you can say:(21 * 7) (3x)  instead of (21)(7)(3x)

And it would be equal to the old version.

(To answer your other question, the commutative property is you can move around all the parts of the equation as long as it's addition or multiplication.)

So basically, it would be the first one you sent me.

This is super hard i needd help

Answer:

2587mm^3 approx!

Step-by-step explanation:

first you divide the nut into 6 part(in triangle now, by joining centre to each edge)

let's take one part of the triangular shape then area of that part can be found by using 1/2×base×height

i.e, 1/2×13×15=97.5(mm^2)

now when we consider depth of that traingular part,we will get volume of that part as area×depth

i.e, 97.5×6=585(mm^3)

now volume of all the 6 triangular part is 585×6=3510(in mm^3)

now take circular cavity in consideration, it's volume will be π(7^2)6=923(mm^3) approximately

now reqired volume will be volume of that hexagonal part minus that of circular cavity

=3510-923

=2587mm^3
