The number next to a variable, for example: 5x, is called a coefficient. And all you do is multiply the number with the variable
Answer:
2x6 + 4x5 + x4 + 11x3 + 2x2 + 4x + 4
Step-by-step explanation:
Part a : you could draw a line from each corner to the middle
This would give you 7 triangles in total
Part b : area of one triangle : 4.5*7.8 = 35.1 / 2 = 17.55in <-- area of 1 triangle
Part c : so if there are 7 triangles and the area of 1 triangle is 17.55, you would do:
7 * 17.55 = 122.85
3.92 rounded to the nearest tenth should be 4.00 or 4, sorry if I’m wrong, have a good rest of your day/night
