Answer:

Step-by-step explanation:

We can use to formula of finding the area of a trapezoid in this problem.

<em>Formula: </em>[(<em>b</em>1 + <em>b</em>2)/2] *<em>h,</em> where <em>b</em>1 and <em>b</em>2 are the bases and <em>h</em> is the height.

<em>b</em>1 can be the bottom base, which has a length of 21 units.

<em>b</em>2 can be the top base, which has a length of (21-9-3)+3 = 12 units.

<em>h</em> has a length of 8, since it is the height.

Plugging these into the formula, we can see that the area of the entire figure is (21+12)/2 * 8 = 33/2 * 8 = 33*4 = <u>132</u><em> </em>units².

Hope this helps! :)

Answer:

132 square units

Step-by-step explanation:

First, I would figure out the areas of the right triangles

Left triangle:  1/2(6x8) =24 units²

Right triangle:  1/2(8x3) = 12 units²

entire rectangle between triangles: 12x8 = 96 units²

add all areas together:  24+12+96 = 132 units²

2sin^(-2490)+tan 1410
givi [52]
2sin²(-2490)+tan 1410=2sin²(-330-6*360)+tan (330+3*360)=
=2sin²(-330)+tan (330)=2 sin²(30-1*360)+tan (-30)=
=2sin²(30)-tan (30)=2(1/2)²-√3/3=1/2-√3/3)=(3-2√3)/6

Answer: 2 sin²(-2490)+tan (1410)=(3-2√3)/6    (≈-0.07735...)

Select the correct answer. Using synthetic division, find (2x4 + 4x3 + 2x2 + 8x + 8) ÷ (x + 2). A. B. C. D.
Mamont248 [21]

Step-by-step explanation:

If you use synthetic division, you get,

2x {}^{3}  + 2x + 4 +  \frac{0}{x + 2}

Which is,

2x {}^{3}  + 2x + 4
