Answer:
Step-by-step explanation:
given the ratio of similar sides = a : b , then
ratio of areas = a² : b²
Given
ratio of sides = 5 : 3 , then
ratio of areas = 5² : 3² = 25 : 9 =
Step-by-step explanation:
Put A = 2, B = 3, C = 9 and D = 15 to the given expressions.
Use PEMDAS.
-A + C - (D : B)
-2 + 9 - (15 : 3) = -2 + 9 - 5 = 7 - 5 = <u>2</u>
B × (-C) - (-D) + A
3 × (-9) - (-15) + 2 = -27 + 15 + 2 = -12 + 2 = <u>-10</u>
(C + D) : B + A
(9 + 15) : 3 + 2 = 24 : 3 + 2 = 8 + 2 = <u>10</u>
D : B + A - C
15 : 3 + 2 - 9 = 5 + 2 - 9 = 7 - 9 = <u>-2</u>
