I think is C or B
Because
3(x-2) = a+ 3x
3x 6 = a + 3x
3x+3x= 6
So
6=a + 6x
Answer:
10%
Step-by-step explanation:
3 more students this year
3/30 reduced= 1/10 or 10%
We have to simplify:
√ ( - 28 )
We know that √ (-1 ) = i ( the imaginary unit )
√ ( - 28 ) = √ 28 * ( - 1 ) = i √ ( 28 ) = i √ ( 4 * 7 ) = 2 i √( 7 )
But there is not such solution among the options.
Only correct answer ( using the imaginary unit ) is:
C. i (square root) 28
