Carpenters use a tool called a speed square to help them mark right angles . A speed square is a right triangle
Ronch [10]

Answer:

A. Area = \frac{1}{2}(2x^2 - 2x - 24)

B. Area = 3.75 in^2

Step-by-step explanation:

A. Area = \frac{1}{2}bh

Where,

b = 2x + 6

h = x - 4

Plug in the values to get a polynomial that represents the area of the tool

Area = \frac{1}{2}(2x + 6)(x - 4)

Area = \frac{1}{2}(2x(x - 4) + 6(x - 4)

Area = \frac{1}{2}(2x^2 - 8x + 6x - 24)

Area = \frac{1}{2}(2x^2 - 2x - 24)

B. To find area, when x = 4.5 in, plug in the value of x into the equation for the area of the tool.

Area = \frac{1}{2}(2(4.5)2 - 2(4.5) - 24)

Area = \frac{1}{2}(2(20.25) - 9 - 24)

Area = \frac{1}{2}(40.5 - 9 - 24)

Area = \frac{1}{2}(7.5)

Area = 3.75 in^2
