Answer:

Option D.

Step-by-step explanation:

The given expression is (5r + 2)(3r minus 4)

Convert this expression into an algebraic expression.

(5r + 2)(3r - 4)

By distribution law,

= 5r(3r - 4) + 2(3r - 4)

= 15r² - 20r + 6r - 8

= 15r² - 14r - 8

Now convert the algebraic expression into the language form.

15r squared minus 14r minus 8

Therefore, option D is the answer.

Answer:

Vertical change of point C to B = 4.5

Vertical change of point A to D = -4

Step-by-step explanation:

Vertical change of a point is the rise of the given point.

Now we have to calculate the rise of point C to B,

y-coordinate of the point C → -2.5

y-coordinate of the point B → 2

Rise from C to B = 2 - (-2.5)

                           = 2 + 2.5

                           = 4.5

Similarly, y - coordinate of point A → 2

y - coordinate of point D → -2

Vertical change or rise = -2 - 2

                                      = -4

Therefore, vertical change of point C to B = 4.5

Vertical change of point A to D = -4

Share 3200 ml of water in the ratio 4:1:3​
Amiraneli [1.4K]

Answer:

1600 ml, 400 ml, 1200 ml

Step-by-step explanation:

Given ratios are: 4:1:3

Let the shares of the given ratios be 4x, x, 3x

\therefore \: 4x + x + 3x = 3200 \\  \\  \therefore \: 8x = 3200 \\  \\  \therefore \: x= \frac{ 3200}{8} \\  \\ \therefore \: x=400 \\  \\  \implies \\ 4x = 4 \times 400 = 1600 \\  \\ 3x = 3 \times 400 = 1200 \\  \\
