Answer 1

Answer:

x = -7

Step-by-step explanation:

Replace the x with -7 and add 4 to -7 to get -3. Then multiply by 7 to get -21.

Answer 2

Answer:

X = -7

Step-by-step explanation:

=> 7(x + 4)= -21

multiply all the terms in the bracket by 7

=> 7x + 28 = -21

make x the subject of formula

=> 7x = -21 -28

subtract the value

=> 7x = -49

divide both side by 7

=> x = (-49)/7

divide -49 by 7

=> x = -7

Find the length and width of rectangle CBED, and calculate its area.

Answers

Answer:

170 units

Step-by-step explanation:

60+60+25+25=170

The 60 and 60 can be found by adding the length, 20+35+5.

The 25 and 25 can be found by taking 55+8-(30+8) for the widths.

Answer:

Step-by-step explanation:

Length = DE =OP

OP = 5 + 20 + 35 = 60 ft

Length of the rectangle CBED = 60ft

Width CD = CJ - (DG +GJ)

                = 55 - (8 + 30)

                = 55 - 38

                 = 17 ft

Area of CBED = length * width

                        = 60 * 17

                         = 1020 ft²

The expression to represent the perimeter of Melissa’s garden in terms of x is P = 8x + 14

Perimeter of a rectangle

The formula for calculating the perimeter of a rectangle is given as

P = 2(x+ y)

where;

x = 3x + 2

y = x + 5

Substitute

P = 2(3x + 2 + x + 5)

P = 2(4x + 7)
P = 8x + 14

Hence the expression to represent the perimeter of Melissa’s garden in terms of x is P = 8x + 14

The temperature outside changed from 94°F to 46°F over a period of eight days. If the temperature changed by the same amount each day, what was the daily temperature change?

Answers

Answer:

6°F

Step-by-step explanation:

First, subtract 46 from 94 (94-46) and you will get 48.

Then, divide 48÷8 (because the time period is 8 days) and you will get 6.

Therefore, the daily temperature change is 6°F.

How do i figure out the degrees?

Answers

Answer:

  41°

Step-by-step explanation:

This problem involving the Law of Cosines has been mostly worked for you. The value of the cosine is the solution to the remaining one-step linear equation. The inverse cosine function (cos⁻¹ or arccos) is used to find the angle from the value of the cosine.

  -1125 = -1500·cos(A)

  cos(A) = -1125/-1500 = 3/4 . . . . . divide by -1500 (this is the one step)

  A = arccos(3/4) ≈ 41.4096°

The angle formed by the lines to the lampposts is about 41°.

__

Additional comment

If you find the angle using the ACOS( ) function of a spreadsheet, you will always get the result in radians. Most calculators offer the choice of units for angles, so be sure you set the mode appropriately.

In the calculator screenshot, there is a decimal point in the fraction to force the angle result to be displayed as a numerical value. Otherwise, this calculator shows cos⁻¹(3/4), which isn't terribly helpful.

A semicircle is drawn onto one of the shorter sides of a rectangle. The shorter side of the rectangle measures 4 centimeters. The area of the figure is 41. 4 square centimeters. What is the length of the longer side of the rectangle?Use 3. 14 for π. Enter your answer as decimal in the box

Answers

The length of the longer side of the rectangle is 8.78cm

Area of composite figure

The formula for calculating the area of a rectangle is expressed as:

A = lw

For a semicircle;

A = πr²/2

r is the radius

Area of the figure = lw + πr²/2

Substitute the given paramters

41.4 = 4w +  π(2)²/2

41.4 = 4w + 6.28
4w = 41.4 - 6.28

4w = 35.12

w = 35.12/4

w=  8.78 cm

Hence the length of the longer side of the rectangle is 8.78cm

Factor the expression by the greatest common factor

Answers

Answer:

2(8w + 1)

Step-by-step explanation:

Look on either side of the plus sign. What ever you see that is common is a common factor. In this case it is also the greatest common factor.

2 appears on both sides of the plus sign.

2(16w/2 + 2/2)

Hello.

Remember that factoring is the opposite of distributing.

Factoring looks like this:

ab+ac=a(b+c) [tex]\longmapsto[/tex] factor out the greatest common factor

In this case, the Greatest Common Factor is

2

Now, divide both terms of the expression by 2.

2(8w+1)

Is this right? We can easily check by using the Distributive Property and distributing 2. Then, we can compare both expressions and see if we ended up with the original expression.

16w+2

See? We have the original expression.
