Answer:
n = 8
Step-by-step explanation:
(n−2) × 180 is the formula to find the interior angles of a polygon
(n−2) × 180 = 1080
Divide each side by 180
(n−2) × 180/180 = 1080/180
n-2 =6
Add 2 to each side
n-2+2 = 6+2
n = 8
Answer: 26.32% (rounded to the hundredths)
Answer:
70m²
Step-by-step explanation:
Area of the plot=½×28×15
= 210m²
Area used by rose plants=⅔×210 =140m²
Area used by marigold=210-140
=70m²
3a + b × a - b would be 3a² + ab + 3ab + b² =
3a² - 4ab - b² aka B.
