First, find the area of the big rectangle:

A=lw

A= 17*20

A=340 cm^2


Next, find the area of the trapezoid.

A=base1+base2. *H
———————-
2

A=6+12
———- * 6
2

A= 54 cm^2


Now, subtract the area of the trapezoid from the bigger rectangle.

340-54=286

So, the shaded area is 286 cm^2. That’s ur answer!

Please help with this
Elena L [17]

Here

radius( r) =12/2=6 in.

height(h)=13 in.

now,

volume of hemisphere(V1)=

\frac{2}{3} \pi \:  {r}^{3}  =  \frac{2}{3}\pi  {6}^{3}  = 144\pi \: cu. \: in.

volume of cylinder(V2)=

\pi {r}^{2} h = \pi \times  {6}^{2}  \times 13 = 468\pi \\

now total volume=V1+V2

=144Pi +468pi

=212pi

Please help you don’t even have to solve it, I just need the equation
Vanyuwa [196]

Step-by-step explanation:

Since the 2 side lines are parallel,

2x + 40 + 5x = 180 \\ 7x + 40 = 180

(Note that you can further simplify the equation if you wish to, this is a general equation.)

(Equation formed due to Corresponding angles and Sum of angles on the same straight line)

Combine the radicals. 3√5-8√5+2√5
weeeeeb [17]

Answer:  -3\sqrt{5}

-3 times the square root of 5

=============================================

Explanation:

Let x = \sqrt{5}

Replace all the root 5 terms with x and we go from

3\sqrt{5}-8\sqrt{5}+2\sqrt{5}

to

3x-8x+2x

From here, combine like terms to get

3x-8x+2x = -5x+2x = -3x

and the last thing to do is replace the x with sqrt(5)

-3x = -3\sqrt{5}

Meaning that,

3x-8x+2x = -3x

3\sqrt{5}-8\sqrt{5}+2\sqrt{5} = -3\sqrt{5}
