Triangle TRI has a base of m centimeters and a height of n centimeters. Rectangle RECT has a length of n centimeters and a width
miskamm [114]

Answer:

Area of a triangle = \frac{1}{2} area of rectangle

Step-by-step explanation:

Given:

Height of triangle = n cm,  Base of triangle = m

Length of rectangle = n cm, Width of rectangle = m cm

Area of ΔTRI = \frac{1}{2}  base × height

                     =  \frac{1}{2}  ( m ) × (n)   ⇒ \frac{1}{2} mn

Area of Rectangle RECT =  Length × Width

                                          = m × n ⇒  = mn

Comparing Area of triangle and rectangle.

\frac{1}{2} mn =  mn

We can conclude that area of triangle is half of the area of rectangle.

Explain why the equation (x-6)^-13=12 has two solutions. Then solve the equation to find the solutions. Show your work.
Gala2k [10]

Answer:

x = 10 and x = (-2) are the solutions.

Step-by-step explanation:

In the given equation (x - 4)² - 28 = 8

we will first find the zero factors which will further decide the number of solutions.

(x -4)² - 28 = 8

(x - 4)² -28 - 8 = 8 - 8 (By subtracting 8 on both the sides of the equation)

(x - 4)² - 36 = 0

(x - 4)²- 6² = 0

(x - 4 - 6)(x - 4 + 6) = 0

(x - 10)(x + 2) = 0

Now the equation only two zero factors or two solutions.

x = 10 and x = -2

Answer is two solutions only x = 10 and x = (-2)
