Step-by-step explanation:
Split the figure into 2 parts, triangle and rectangle (I believe you know what I'm talking about)
area of triangle = 1/2 x 20 x (16-7) = 90cm^2
area of rectangle = 20 x 7 = 140cm^2
total area = 90 + 140 = 230cm^2

Answer: - 2.4x^2 - 1.5x - 11.4
Step-by-step explanation:
- 4.1x^2 + 0.9x - 9.81.7x^2 - 2.4x - 1.6 = - 2.4x^2 - 1.5x - 11.4
I can't tell the numbers apart as there are no colours so I did one answer a with them all being one digit numbers and another answer as them being 2 digit numbers...
1 digit:
5 + 4 + 3 + 3 + 2 + 2 +1 = 20
20 ÷ 7 = 2.86
2 digit:
54 + 33 + 22 + 1 = 110
110 ÷ 5 = 22
