Answers

Answer 1

Answer: $1.\n\underline{y}+\underline{1.2y}+\underline{1.2z}\to\boxed{y;\ 1.2y;\ 1.2z\to\boxed{D}}$

$2.\n2+17x-5x+9=(17x-5x)+(2+9)=\boxed{12x+11\to\boxed{B}}$

$3.\n3(5y+6)-4=(3)(5y)+(3)(6)-4=15x+18-4=\boxed{15y+14\to\boxed{C}}$

$4.\n81-27p=27\cdot3-27\cdot p=\boxed{27(3-p)\to\boxed{B}}\nbut\n81-27p=9\cdot9-9\cdot3p=\boxed{9(9-3p)\to\boxed{A}}$

What dose 5h-2+9h equal explain☺

Answers

Start out by combining LIKE TERMS
5h-2+9h
in this case 9h and 5h are like terms so you would add both of those together.
9h+5h=14h
-2 has no like terms so we can't do anything with it our final answer would be:
14h-2
