Split the figure into 3 shapes: a trapezoid,a rectangle and a triangle

Area of trapezoid

A= 1/2(b1+b2) h

A = 1/2(3 +9)(8)

A = 1/2(12)(8)

A = 48 square units

Area of rectangle:

A = L x W

A = 9 x 8

A = 72 square units

Area of triangle

A = 1/2bh

A = 1/2(3)(8)

A = 12 square units

Area of figure = 48 square units + 72 square units + 12 square units

= 132 square units

Answer

132 square units

Tori examined the pattern of exponents in the table.

gregori [183]

Answer:

The value of b = 1/36

As exponent decreases, each previous value is divided by 6

If the table was extended, the value of 6^-3 would be 1/216

Step-by-step explanation:

Given in the question a table containing power of 6

We will use negative rule of exponent to write the equivalent of negative power of 6

b^{-n}= 1 / b^{n}

we know that

$6^{1}=6$

$6^{-1} =\frac{1}{6^{1} }$

= 1/6

and

$6^{2} = 36$

So,

$6^{-2} = \frac{1}{6^{2} }$

$\frac{1}{36}$

If x = √3 − √2 , find the value of ( −1/x)root 2

makkiz [27]

hello

$\dfrac{-1}{x}\sqrt{2}=\dfrac{-\sqrt{2}}{\sqrt{3}-\sqrt{2}}=\dfrac{-\sqrt{2}(\sqrt{3}+\sqrt{2})}{(\sqrt{3}-\sqrt{2})(\sqrt{3}+\sqrt{2})}\\\\=\dfrac{-\sqrt{2}(\sqrt{3}+\sqrt{2})}{3-2}\\\\=-\sqrt{6}-2$

hope this helps
