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

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,

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

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