<span>-28ab-35ab+12b^2-42b^2
add similar element=-</span>28ab-35ab=-63ab
so that..
=-63ab+12b^2-42b^2
add similar element=12b^2-42b^2=-30b^2
=-63ab-30b^2
Multiply without the decimal point, then put it back into the answer.
69 has 0 decimal points 9.2 has 1 therefore the answer will have one decimal point.
multiply 69*92=6348
insert the decimal point and the answer is 634.8

Answer:
The first one.
Step-by-step explanation:
Graph lines as if the inequalities were equal signs.
X = -3 is a vertical line at x = -3, because it's less than we shade to the left. All numbers less than -3 are to the left. The line is dashed because there is no equal to. Only less than. The line is not included in the solution set.
y = -x - 1 is a line with a y-intercept of -1 and a slope of -1. All values that are less that y are below the line. Because it's less than or equal to the line is solid.
