4 will be added to make the given expression a perfect square

Further explanation:

Given term is:

x^2-4x

As there is a square term and a linear term involving x, the expression will be completed using the formula

a^2-2ab+b^2=(a-b)^2

We know that

a^2=x^2

so,

2ab=4x\\2xb=4x\\b=\frac{4x}{2x}\\b=2

Adding (2)^2

x^2-4x+(2)^2

x^2-4x+4

4 will be added to make the given expression a perfect square

Which expression is equivalent to 8(a+3)
Alex777 [14]

Answer:

8a + 24

Step-by-step explanation:

Use Distributive property: a(b +c) = a*b + a*c

Here a = 8 ;  b= a & c = 3

8(a + 3) = 8*a + 8*3

            = 8a + 24

How do you graph y=3x-4 on a coordinate grid
mars1129 [50]

Answer:

You can look at the screenshot

Step-by-step explanation:

So one point of the line is (0, -4) and another point is (4/3, 0). Plot these points on a graph and draw a line.

0, -4 is from making x = 0, and then 4/3, 0 is from making y = 0.

Find the distance represented of the coordinate plane
antiseptic1488 [7]

Answer:

The answer to your question is: letter A

Step-by-step explanation:

From the graph we get the points,

P (2,1)

Q (6,8)

Formula

d = √((x2-x1)² + (y2-y1)²)

d = √((6-2)² + (8-1)²)

d = √ (4² + 7²)

d = √ (16 + 49

d = √65           letter A

PLEASE HELP WILL MARK BRAINLEIST
horsena [70]

Answer:

The picture shows the answer on the graph

Step-by-step explanation:

-2=-3/4×(x-6)

Distribute -3/4 through the parenthesis

-2= -3/4x+9/2

Multiply both sides of the equation by 4

-8=-3x+18

Move the variable to the left side and change its sign

3x-8=18

Move constant to the right side and change its sign

3x=18+8

Add the numbers

3x=26

Divide both sides of the equation by 3

x=26/3

Alternative Form- x=8 2/3 or x=8.6

Cody has $700 in a savings account that pays 4% simple interest. How much will he have in 1 year?
ladessa [460]

Answer:

$ 728

Step-by-step explanation:

Amount of Money Cody has = $700

Simple Interest = 4%

As it is know that interest is always given on annually basis so

Amount of profit he have in one year = Money he have right now * interest

                                                              =700 * 4%

                                                              =700 * \frac{4}{100}

                                                               = $ 28

After one year he will have = total money at that time + Profit

                                              = 700 + 28

                                              = $ 728
