Multiplication is indicated between a number and a variable by writing them next to each other. A "product" is the result of multiplication, so "the product of 167 and b" is written 167b.
If you want a value that is 84 more than that, you get it by adding 84.
Distance from point C to point D: same x coordinate, 4-1=3; 3 units Distance form point D to F: same y coordinate, 5-2=3 Perimeter is the measure of all sides 3+3+3+3=12 Solution: A. 12 units
