Answer:

C -16x + 74/5

Step-by-step explanation:

2(x + 7) - 18x + (4/5)

Expand the brackets.

2x + 14 - 18x + (4/5)

Combine like terms.

(2x - 18x) + (14 + (4/5))

-16x + 14 4/5

Convert 14 4/5 to an improper fraction

14 4/5 = ((14 * 5) + 4) / 5 = 74 / 5

Answer = -16x + 74/5

A stone which is dropped into a dry well hits the bottom in 2.2s how deep is the well. take g=10m/s​
Papessa [141]

Answer:

23.7m

Step-by-step explanation:

Given parameters:

       Time taken = 2.2s

     Acceleration due to gravity = 10m/s

Unknown:

Depth of the well  = ?

Solution:

To solve this problem, we simply apply one of the motion equations;

        S = ut + \frac{1}{2} gt²

    where S = depth of the well

                u = initial velocity

                t = time taken

               g = acceleration due to gravity

 Input the parameters and solve for S;

   Note initial velocity = 0;

     S = \frac{1}{2} x 9.8 x 2.2²

    S = 23.7m

Find m∠3 if m∠5=130 and m∠4 =70
arlik [135]
M∠5=130 <span>and m∠4 =70
</span><span>so
m<2 = 180 - m<5 
m<2 = 180 - 130
m<2 = 50

m<3 = 180 - (m<2  + m<4)
</span>m<3 = 180 - (50+70)
m<3 = 180 - 120
m<3 = 60
