Answer:
the answer is 5
Step-by-step explanation:
f(4) = 3(4) -2
7 - 2 = 5
Answer:
2x^2 + 2y^2 + 2z^2
Step-by-step explanation:
x^2+xy-yx+y^2 + y^2+yz-zy+z^2 + z^2+zx-xz+x^2
First step is to put all the same ones together
( FYI, xy and yx is the same thing, just like how
2 x 3 and 3 x 2 is the same thing) this time I'll bracket the groups to make it easier on the eyes
(x^2 +x^2) + (xy - xy) +( y^2 + y^2) + (yz - yz) +
(z^2 +z^2) + (zx - zx)
2x^2 + 2y^2 + 2z^2
All the others just cancel themselves out, for example, xy-xy
When anything minus themselves it will become 0
Answer:
Given expression is,
9(x+3) = 108
In solving the equation the steps are as follows,
Step 1 : 9x + 27 = 108 ( By distributive property )
Step 2 : 9x = 81 ( Subtracting 108 on both sides )
Step 3 : x = 9 ( Divide both sides by 9)
Hence, by the above explanation we can drag the steps of solution in correct order.
563/.4 is equal to 1,407.5
