Answer:

Option B.

Step-by-step explanation:

The given expression is

$\dfrac{2a-7}{a}\times \dfrac{3a^2}{2a^2-11a+14}$

We need to find the product.

The given expression can be rewritten as

$\dfrac{2a-7}{a}\times \dfrac{3a^2}{2a^2-7a-4a+14}$

$\dfrac{2a-7}{a}\times \dfrac{3a^2}{a(2a-7)-2(2a-7)}$

$=\dfrac{2a-7}{a}\times \dfrac{3a^2}{(2a-7)(a-2)}$

$=\dfrac{(2a-7)3a^2}{a(2a-7)(a-2)}$

Cancel out the common factors.

$=\dfrac{3a}{a-2}$

So, $\dfrac{2a-7}{a}\times \dfrac{3a^2}{2a^2-11a+14}=\dfrac{3a}{a-2}$

Therefore, the correct option is B.

2x - 3 < 11 or 8x -10 < 82: X < 23/2

Part 1
2x-3<11
Add 3 both sides
2x-3+3<11+3
Refine
2x<14
Divide by 2 on both sides
2x / 2 / 14 / 2
Refine
x < 7

Part 2
8x-10<82
Add 10 to both sides
8x-10+10<82+10
Refine
8x<92
Divide by 8
8x / 8 / 92 / 8
Refine
x < 23 / 2
