Question 1
Simplify: 11(3x+2)−3(x+1).
Question 2
When d=3, evaluate
21−4(−6d+9)
and
21−4⋅(−6d)−4⋅9
to show that
21−4(−6d+9)=21−4⋅(−6d)−4⋅9
Question 3
When z=−3, evaluate 2(7z+8) and 2⋅7z+2⋅8 to show that 2(7z+8)=2⋅7z+2⋅8.
Question 4
Simplify: 7(2q+1)+(3q−5).
Question 5
When g=1, evaluate 1/3(6g−18) and 1/3⋅6g−1/3⋅18 to show that 1/3(6g−18)=1/3⋅6g−1/3⋅18.
Question 6
When y=−5, evaluate
−(6y+15)−6(4y+1)
and
−6y−15−6⋅4y−6⋅1
to show that
−(6y+15)−6(4y+1)=−6y−15−6⋅4y−6⋅1
Question 7
Simplify: 5(1/6a+5/7).
Question 8
Simplify: 2(5y−1)+10y(1−y).
Solution
Question 1
Simplify: 11(3x+2)−3(x+1).
Ans: 30x + 19
Question 2
When d=3, evaluate
21−4(−6d+9)
and
21−4⋅(−6d)−4⋅9
to show that
21−4(−6d+9)=21−4⋅(−6d)−4⋅9
Ans: 21 – 4(-6d + 9) = 57, 21 – 4⋅ (-6d) -4⋅9 = 57……………please follow the link below to purchase the solution at $4
