Question

3y(2y-7)-3(y-4) if y = 2

Answer 1

Answer:

3y(2y-7)-3(y-4)

3×2(2×2-7)-3(2-4)

6(4-7)-3(2-4)

24-42-6+12

-12

Answer 2

Answer

y=-12

Step-by-step explanation:

3y(2y-7)-3(y-4) if y = 2 (given)

Now multiply both

${6y}^{2 } - 21y - 3y + 12$

${6y}^{2 } - 24y + 12$

Now put the value of y=2

$y</strong><strong>=</strong><strong>2</strong><strong>$

6(2)^2-24(2)+12

6(4)-48+12

24-48+12

-24+12

24-12

(-12)
