Answer:

Area = 7

Perimeter = 21 m

Step-by-step explanation:

Remark

The perimeter is just the sum of the three sides of the triangle.

The Area is the base * height /2

Givens

Perimeter: Three sides: 5 + 7 + 9

height: 2 meters

Formula

Area = 1/2 Base * Height

Area = 1/2 7 * 2

Note:

Just so you know the height should be almost 5. 2 is an impossible amount for the height.

Area = 1/2 * 7 * 2

Area = 7 m^2

Perimeter = 5 + 7 + 9

Perimeter = 21

What is the difference of the fractions? Use the number line and equivalent fractions to help find the answer.

ipn [44]

The difference of the fraction is $\mathbf{ -\dfrac{3}{4}}$ by using equivalent expressions.

<h3>What is a number line?</h3>

A number line is a diagrammatic representation of real numbers on the graduated line. It ranges from negative axis to positive axis with 0 being the center position.

A sketch showing the representation of the difference in the mixed fractions can be seen in the image attached below.

Using equivalent expressions to determine the difference between the mixed fractions, we have;

$\mathbf{ = -2\frac{1}{2} - (-1\dfrac{3}{4}) }$

$\mathbf{ = -2\frac{1}{2} +1\dfrac{3}{4} }$

$\mathbf{ = -\dfrac{5}{2} +\dfrac{7}{4} }$

$\mathbf{ = -\dfrac{3}{4}}$

A new truck costs $32,000 if the truck is worth 24,500 after three years write an explicit formula for the value of the car afte

Debora [2.8K]

Answer:

Step-by-step explanation:

depreciation for three years = 32000 - 24500 = $ 7500

depreciation per year = 7500/3 = $ 2500

depreciation % = (2500/32000)*100 = 7.81%

Value of truck after n years = 32000 * (7.81%)*n

Expand and simplfy (2x+1)(x+3)

Nina [5.8K]

Answer:

(2x+1)(x+3)

2x(x+3)+1(x+3)

2x2+6x+x+3

2x2+7x+3 (2x2 means two x square)

if you want you can also multiply 2x+3 by x+3

like this:

(2x+1)(x+3)

x(2x+1)+3(2x+1)

2x2+x+6x+3

2x2+7x+3 (2x2 means two x square)

They will both give you the same answer.
