Answer:

area = 62ft

Step-by-step explanation

so you section the polygon into a big rectangle and 2 small rectangles

the area of the small rectangle will be 2ft x 3ft which will be 6 ft, and as there are 2 of them the area of it will be 12ft

the area of the big rectangle will be 10ft x 5ft, as 8ft - 3ft is 5ft so 5x10=50ft

now add the areas you got, 50+12 which is 62ft

hope this helps:)

Help solve the above equation

Tresset [83]

Answer:

$\dfrac{1}{27}$

Step-by-step explanation:

$n^{-\frac{2}{3}}=9$

Rewrite:

$\dfrac{1}{\sqrt[3]{n^2}}=9\\\\9\sqrt[3]{n^2}=1$

Cube both sides:

$729n^2=1$

Divide both sides by 729:

$n^2=\dfrac{1}{729}$

Take the square root of both sides:

$n=\sqrt{\dfrac{1}{729}}=\dfrac{1}{27}$

Hope this helps!

The sum of three numbers is 103. The second number is 5 less than the first. The third number is 4 times the first. What are the

madreJ [45]

Answer:

The numbers are 18, 13, and 72.

Step-by-step explanation:

Let the three numbers be represented by a, b, and c.

The sum of the three is 103. Thus, we can write that:

$a+b+c=103$

The second number is five less than the first. So:

$b=a-5$

And the third number is four times the first. So:

$c=4a$

Substitute:

$a+(a-5)+(4a)=103$

Solve for a. Combine like terms:

$6a-5=103$

Add five to both sides:

$6a=108$

And divide both sides by six. Therefore:

$a=18$

So, the first number is 18.

Since the second number is five less than the first, the second number is 13.

And since the third number is four times the first, the third number is 72.

The rectangle below has an area of x^2+8x+15x

Darina [25.2K]

Answer:

The length of the rectangle is x+5.

Step-by-step explanation:

Given : The rectangle below has an area of $x^2+8x+15$ square meter and a width of $x+3$ meter.

To find : What expression represents the length of the rectangle?

Solution :

The area of the rectangle is given by,

$\text{Area}=\text{Length}\times \text{Breadth}$

$\text{Area}=x^2+8x+15$

$\text{Breadth}=x+3$

$x^2+8x+15=\text{Length}\times(x+3)$

$\text{Length}=\frac{x^2+8x+15}{x+3}$

$\text{Length}=\frac{(x+5)(x+3)}{x+3}$

$\text{Length}=x+5$

Therefore, the length of the rectangle is x+5.
