3y+2z
It is the same as 8y+8z
z + 8 - 2 is an expression, not an equation. An expression cannot be solved. At best, you can simplify it to z + 6.
-4(7x-3y-z)-(-6)(9x-z+2)
You can't simplify it any further than 3x+2y+6z=24, unless you have been given values of x,y and z or other equations to find x,y and z.
simplify the square foor of 49 times x to the third time y to the sixth times the absolute value of z squared
To find the multiplicative inverse of a complex number z = (a + bi), divide its complex conjugate z* = (a - bi) by z* multiplied by z (and simplify): z = 4 + i z* = 4 - i multiplicative inverse of z: z* / (z*z) = (4 - i) / ((4 - i)(4 + i) = (4 - i) / (16 + 1) = (4- i) / 17 = 1/17 (4 - i)
is eassy
3a * * * * * Actually, it is 4a.
Expand z plus 11 times z plus 11 = (z+11)(z+11) = z2 + 22z + 121.
If you simplify the equation (s+t+s) the answer is 2s+t
