Answer:x^2-x-3

Step-by-step explanation:

step 1-find area of rectangular lawn

(2x+1)(x+1)=2x^2+3x+1

step 2-find area of garden

(x+2)(x+2)=x^2+4x+4

step 3- subtract the two

=x^2-x-3

Answer:

[tex]-\frac{1}{4}[/tex]

Step-by-step explanation:

1. Use the slope formula:

[tex]slope=\frac{y_2-y_1}{x_2-x_1}[/tex]

2. Using the x and y values from both points (it doesn't matter which order you choose the points in as long as you keep their numbering consistent, i.e. point 1 = [tex](x_1, y_1)[/tex] and point 2 = [tex](x_2, y_2)[/tex]) plug into the formula.

[tex]slope=\frac{4-(-2)}{-18-6}[/tex]

3. Simplify the fraction.

[tex]slope=\frac{6}{-24} =-\frac{1}{4}[/tex]

Answer:

percentage change divided by real value, *100.

421-376 = 45

Step-by-step explanation:

Answer:

2 2/3

Step-by-step explanation:

absolute value means the distance between a number and 0 so therefore the absolute value s 2  2/3

I like to use the way flip the second fraction then cross cancel then multiply.

(-2/7)/(-8/21)

= (-2/7)(-21/8) (cross cancel) so 8 / 2 = 4 and 21 / 7 = 3. The 7 and 2 becomes 1.

= (-1/1)(-3/4)

= 3/4 or decimal 0.75

Answer:

3/4

Step-by-step explanation:

(-2/7) / (-8/21)

= (-2/7) * (-21/8)

=(-2*-21) / (7*8)

=42/56

= 3/4 -simplified

Answer:

x=5

Step-by-step explanation:

6x+12x=90

18x=90

x=90/18

x=5

Answer:

x =5

Step-by-step explanation:

To solve for x:

1: add like-terms

          6x+ 12x = 90

Now it is:  18x =90

2: use division on both sides to solve for the variable

           18x= 90

           18x/18 = 90/18

              x = 5

The answer is (-2, 1) Step-by-step explanation

Answer:

18

Step-by-step explanation:

First we need to know how many vehicles they can wash in a minute.

1. So you do 10/45. You get 4.5

2. Now that you know that they wash 1 vehicle in 4.5 minutes, you mulitply that by 4. And you get 18.

Hope this helps! :D

Answer:

The independent variable is the week's, the dependent variable is the height in inches.

Step-by-step explanation:

The independent variable is the variable that when changed, something changes because of it. So for example, for plant A, in 2 weeks (independent) thevplant will grow 2 inches (dependent). The dependent variable is the variable that changes because of the independent.

Extra Information is below

Y-intercept: The y-intercept is when the line crosses with the line when the x-axis is 0. For example, plant B is by 0 weeks, it was 4 inches. The y-intercept will be 4 inches because that is where the plant started before any change in the independent variable.

Slope: Y = mx + b. To get the answer for this equation, you first need to find out the constant, the constant if we're using plant A, is 6. The constant is also the y-intercept. The equation will look like Y = mx + 6. The m is the number that when multiplied with the independent variable, then added with the constant, you get y. The m for plant A is 1, the equation should look like y = 1x + 6. Now change the x with the independent variable in the table. The independent variable is 2, so y = 1(2) + 6, y = 2 + 6, y = 8.

Answer:

The answer is 84000 milligrams

Step-by-step explanation:

The formula is to multiply the mass value by 1000

Answer:

84000 mg

Step-by-step explanation:

1 gram = 1000 mg so 84 times 1000 is 84000

x = 4°         Alternate Exterior Angles

Step-by-step explanation:

[tex]\begin{array}{cc}Statement&Reason\\21x + 6= 90&Alternate -Exterior -Angles\\\end{array}\right][/tex]

Solve for x:

21x + 6° = 90°

21x = 84°

x = 84°/21

x = 4°

-Chetan K

Step-by-step explanation:

what's the question ? it does not say.

I assume it is "how many packages of what size were sold ?"

x = number of small packages

y = number of medium packages sold

z = number of large packages sold

x + y + z = 9

7x + 12y + 15z = 86

y = 3z

these are the 3 equations we get out of the question.

we put the third equation into the other two :

x + 3z + z = x + 4z = 9

7x + 12×3z + 15z = 7x + 36z + 15z = 7x + 51z = 86

it of this first equation we get

x = -4z + 9

and putting that into the other equation :

7×(-4z + 9) + 51z = 86

-28z + 63 + 51z = 86

23z = 23

z = 1

y = 3z = 3×1 = 3

x = -4z + 9 = -4×1 + 9 = -4 + 9 = 5

so, 5 small, 3 medium and 1 large packages were sold.

Answer:

Your new total with the sale is 76.83 dollars

Step-by-step explanation:

-2x+9y=41.... equation 1

-2x-5y=1 ....equation 2

________________

14y=43

y=43/14

y=43/14 in equation 1

-2x+9(43/14)=41

-2x+387/14=41

-2x=41-387/14

-2x=187/14

x=187/-28

x=187/28 , y=43/14

if you want to check your answer

-2(187/28)+9(43/14)=41
