First of all, the first power of 'x' is the highest power in the whole equation,
so we only expect one solution.

You said that <span><u>3x+9 = 21+7x </u>

Subtract 3x from each side:

9 = 21 + 4x

Subtract 21 from each side:

-12 = 4x

Divide each side by 4 :

<u>-3 = x </u>
</span>

Name a fourth point in plane UVX
sveticcg [70]

Answer:

The correct option is;

W

Step-by-step explanation:

The number of points that defines a plane in a Euclidean space in all dimensions is either three points which are not on the same line, or two colinear points and a third point not on the line

The given points of the plane are UVX, which gives the plane as being diagonal to the cube and perpendicular to the side face of the cube.

The fourth point in plane UVX is therefore W.

Pani-rosa [81]
No because the exponent on 6^3 is 216 and if you use (4•6)^3 then you’ll have to multiply the quotations and then Square it to the third
