Associative property of multiplication . Here we have +6 . there is a + sign inbetween. so it does not comes under Associative property of multiplication
B. 6 × (4 + 2) = 36
Here we have 4 +2 . there is a + sign inbetween. so it does not comes under Associative property of multiplication
C. (6 + 4) × 2 = 20
Here we have 6 + 4 . there is a + sign inbetween. so it does not comes under Associative property of multiplication
D. (6 × 4) × 2 = 48
Here we have 6 times 4 times 2. so it comes under Associative property of multiplication
Given that the base of the triangle is x m, the height is 3m less than twice it's base then the height will be represented by the equation: (2x-3) m thus the area will be: Area=1/2bh Area=1/2x(2x-3)=17.5 x^2-1.5x=17.5 writing the above equation is quadratic form of ax^2+bx+c=0 we get: x^2-1.5x-17.5=0
