Good morning ☕️

Answer:

<h2>3(2x − y)(2x + y)</h2>

Step-by-step explanation:

12x² − 3y² = 3×4x² − 3y²

                = 3(4x² − y²)

                = 3((2x)² − y²)

                = 3(2x − y)(2x + y)

Answer:

315881.53

Step-by-step explanation:

We first need to figure out how long it takes for the money to triple

let x= number of years it takes for the money to tirple

3=(1+\frac{.04}{365})^{365x}\\log_{1.0001}3=365x\\10025.38644=365x\\27.46681216=x

Now plug that value into the continously compounding formula

80000*e^{27.4668*.05}=315881.5314

Which rounds to

315881.53

Answer:

<em>$600.00</em>

Step-by-step explanation:

To find the answer we must first <em>divide 3 by 100 to find its actual worth</em>,        <em>3 ÷ 100 = 0.03</em>.  Take <em>0.03 and multiply it by 5,000</em>, and you get<em> 150</em>.  Now we have the <em>annual interest in a year</em>, so lets <em>multiply it by 4 years</em>, and we get <u><em>$600. </em></u>

What is the area where if this figurine ?ixl question
nydimaria [60]

Answer:

The area of the figure is 97 square inches

Step-by-step explanation:

In the given figure

<em>To find the area of the figure we can find </em><em>the area of the big rectangle with dimensions 7 inches and 19 inches</em><em> and subtract from it </em><em>the area of the small rectangle with dimensions 4 inches and 9 inches</em>

∵ The area o the rectangle = length × width

∵ The dimensions of the big rectangle are 7 inches and 19 inches

∴ The width = 7 inches

∴ The length = 19 inches

→ Substitute them in the rule of the area above

∵ The area of the big rectangle = 19 × 7

∴ The area of the big rectangle = 133 inches²

∵ The dimensions of the small rectangle are 4 inches and 9 inches

∴ The width = 4 inches

∴ The length = 9 inches

→ Substitute them in the rule of the area above

∵ The area of the small rectangle = 9 × 4

∴ The area of the small rectangle = 36 inches²

→ Subtract the area of the small rectangle from the area of the big

   rectangle to get the area of the green figure

∵ The area of the figure = the big area - the small area

∴ The area of the figure = 133 - 36

∴ The area of the figure = 97 inches²

∴ The area of the figure is 97 square inches
