Step-by-step explanation:
Solutions:-
b)
(3x+7)×(6x)
=> (3x)(6x) + 7(6x)
=> 18x^2+42x
(3x+7)×(6x) = 18x^2+42x
c)
Given amount = Rs.3240
Given ratio = 11:7
Let the amount of A be Rs. 11X
Let the amount of B be Rs. 7X
Total mount
= 11X +7X
= Rs. 18X
But given amount = Rs.3240
=> 18X = 3240
=> X = 3240/18
=> X = Rs.180
11X = 11×180 = Rs. 1980
7X = 7×180 = Rs. 1260
Share of A = Rs. 1980
Share of A = Rs. 1980Share of B = Rs. 1260
d)
Given that
(-4/15)×(-6/7)×(35/12)
=> (-4×-6×35)/(15×7×12)
=> 840/1260
=> 3/2 or 1.5
(-4/15)×(-6/7)×(35/12) = 3/2
