Answer:

B) -18

Step-by-step explanation:

To find the missing coefficient, we have to multiply (2d - 5)(2d -4) using FOIL method.

FOIL method is used to multiply two binomials.

F- Multiply the first terms of each binomials

O-Multiply the outer terms

I- Multiply the inner terms

L-Multiply the last terms

(2d - 5)(2d - 4) = (2d)(2d) +2d(-4) -5(2d) -5(-4)

Simplifying this, we get

4d^2 -8d -10d + 20

Simplify the like terms, we get

4d^2 -18d +20

Here the missing term is -18d

The coefficient is -18

Therefore, answer is -18.

The lines on a 2-cup liquid measuring cup divide each cup into eighths. If you measure 1 3/4 cups of water, between which two qu
masya89 [10]

Answer:

1 3/4 cups is between the 13th and 15th lines from the bottom.

Step-by-step explanation:

The bottom of the cup has no line and corresponds to 0 eights.

1st line up: 1/8 cup  

2nd line up: 2/8 cup    this is also called 1/4 cup

3rd line up: 3/8 cup

4th line up: 4/8 cup     this is also called 1/2 cup

5th line up: 5/8 cup

6th line up: 6/8 cup     this is also called 3/4 cup

7th line up: 7/8 cup

8th line up: 8/8 cup     this is also called 1 cup

9th line up: 9/8 cup

10th line up: 10/8 cup    this is also called 1 1/4 cup

11th line up: 1 3/8 cup

12th line up: 1 4/8 cup     this is also called 1 1/2 cup

13th line up: 1 5/8 cup

14th line up: 1 6/8 cup    this is also called 1 3/4 cup

15th line up: 1 7/8 cup

16th line up: 1 8/8 cup    this is also called 2 cups

1 3/4 cups is between the 13th and 15th lines from the bottom.

To complete the square, how do you find the value that must be added to the expression to make a perfect square trinomial? What
Molodets [167]
Take half of the coefficient of x (which is 2/5) and square it:

[ (1/2)(2/5) ]^2 = (1/5)^2 = 1/25, or 0.04

Thus, to rewrite x^2 + (2/5)x to include a perfect square trinomial,

x^2 + (2/5)x  = x^2 + (2/5)x + (1/5)^2 - (1/5)^2, or

                 (x+1/5)^2 - (1/5)^2, or (x + 1/5)^2 - 1/25

Find the equation of the straigt line
natka813 [3]

Given :

A graph with a straight line on it.

To Find :

The equation of the line.

Solution :

From the given graph we can see that the line passes through point ( 0,6 ) and ( 4,10 ) .

Also, equation of line passes through two points (x_1,y_1) and ( x_2,y_2) is :

y - y_1 = (\dfrac{y_2-y_1}{x_2-x_1})( x - x_1)

Putting all given values, we get :

y - 6 = (\dfrac{10-6}{4-0})( x -0)\\\\y - 6 = x\\\\y -x = 6

Therefore, the equation of line is y - x = 6 .
