Answer:

Step-by-step explanation:

Consider A the area of the triangle

h the height

b the base length

_________

$A=\frac{b*h}{2}$

_________

then

$b =\frac{2A}{h} = \frac{2*120}{12} =\frac{240}{12} =20$

the verticales of triangle XYZ are X(-3,-6),Y(21,-6),and Z(21,4). What is the perimeter of the triangle

andrezito [222]

Answer:

Step-by-step explanation:

The formula of a distance between two points:

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

X(-3, -6), Y(21, -6). Substitute:

$XY=\sqrt{21-(-3))^2+(-6-(-6))^2}=\sqrt{24^2+0^2}=\sqrt{24^2}=24$

X(-3, -6), Z(21, 4). Substitute:

$XZ=\sqrt{(21-(-3))^2+(4-(-6))^2}=\sqrt{24^2+10^2}=\sqrt{576+100}=\sqrt{676}=26$

Y(21, -6), Z(21, 4). Substitute:

$YZ=\sqrt{(21-21)^2+(4-(-6))^2}=\sqrt{0^2+10^2}=\sqrt{10^2}=10$

The perimeter of the triangle XYZ:

$P_{\triangle XYZ}=XY+XZ+YZ$

Substitute:

$P_{\triangle XYZ}=24+26+10=60$

Answer:

2x-5

Step-by-step explanation:

f(g(x) means stick g(x) into f(x) in place of x

f(x) = 2x+1

f(g(x) ) = 2(g(x)) +1

and we know that g(x) = x-3

so replace g(x) with x-3

f(g(x) ) = 2(x-3) +1

Distribute

f(g(x)) = 2x-6+1

= 2x-5
