Answer:

Number of bricks is 5

Step-by-step explanation:

We have volume of wall 60m^3. Then we are also given number of bricks size 20cm ×12cm× 5cm.

By multiplying this number we grt 1200cm^3. But answer is needed in meter so divide 1200 with 100 because to change cm into m we need to divide with hundred. Then we have 12m^3 as volume of bricks.

To get no. of bricks we have formula

N = volume of wall ÷ volume of bricks

N = 60 ÷ 12

N = 5

Thus the number of bricks is 5.

Ask me again if you got confused i will explain it more briefly..

Answer:

6x - 5

Step-by-step explanation:

$Let \: y = 3 {x}^{2} - 5x \\ \\ \frac{dy}{dx} = \frac{d}{dx} (3 {x}^{2} - 5x) \\ \\ = 3 \frac{d}{dx} {x}^{2} - 5 \frac{d}{dx} x \\ \\ = 3(2x) - 5(1) \\ \\ \boxed{\boxed{\huge \purple{\frac{dy}{dx}} \pink{ = } \orange{6x - 5}}}$
