A/3=7/10
21=10a
a=2.1
100a=100*2.1=210
The answer is C because:
It is keeping it identity through the multiplication.
Polynomial with real coefficients always has even number of complex roots. We know that one of them is 2 + 5i so the second one will be 2 - 5i and:

Answer B.
9.4=3x+x
9.4=4x
=2.35
the shorter piece is 2.35 and <u>the longer piece is </u><u>7.05</u>
