7.If x = -2, y =-6 and z=4, find the value of:(2mks)
3YZ
X
To find the value of 3YZ, we need to multiply 3, Y, and Z together.
Given that Y = -6 and Z = 4, we substitute these values into the equation and calculate:
3YZ = 3 * Y * Z
= 3 * (-6) * 4
= -18 * 4
= -72
Therefore, the value of 3YZ when Y = -6 and Z = 4 is -72.
Now, let's move on to finding the value of X. The value of X is already given as -2, so there's no calculation required.
