Alexandra [31]3 years ago
6 0

Answer:

<h2>A = 40 cm²</h2>

Step-by-step explanation:

The formula of an area of a triangle:

A_\triangle=\dfrac{b\cdot h}{2}

<em>b</em><em> - base</em>

<em>h</em><em> - height</em>

<em />

We have <em>b = 8cm, h = 10cm</em>.

Substitute:

A=\dfrac{(8)(10)}{2}=\dfrac{80}{2}=40\ (cm^2)

Ann [662]
Hey there look like you need some help.
If I give you the correct answer mark me brainleist

First you would find the area of the square:        230*230= 52,900Next you would find the area of one on the triangles:        230*187=43,010 * 1/2=  21,505Then you would multiply the area of the one triangle by four:       21,505*4= 86,020Finally, you would add the area of the square to the combined area of the triangles:        86,020+ 52,900=138,920

Which of the following pairs of functions are inverses of each other?
AnnyKZ [126]

Answer:

Step-by-step explanation:

Rearrange each function to solve for x.

Switch x and y,

The resulting equation is the inverse function.

A:

f(x) = y = 5+x

x = y-5

y = x-5

f⁻¹(x) = x-5

g(x) = 5-x ≠ f⁻¹(x)

g(x) is not the inverse of f(x).

:::::

B:

f(x) = y = 2x-9

x = (y+9)/2

y = (x+9)/2

f⁻¹(x) = (x+9)/2

g(x) = (x+9)/2 = f⁻¹(x)

g(x) is the inverse of f(x).

:::::

C:

f(x) = y = 2/x - 6

x = 2/(y+6)

y = 2/(x+6)

f⁻¹(x) = 2/(x+6)

g(x) = (x+6)/2 ≠ f⁻¹(x)

:::::

D:

f(x) = y = x/3 + 4

x = 3y - 12

y = 3x - 12

f⁻¹(x) = 3x - 12

g(x) = 3x - 4 ≠ f⁻¹(x)

g(x) is not the inverse of f(x).
