Carpenters use a tool called a speed square to help them mark right angles . A speed square is a right triangle A . write a polynomial that represents the area of the speed square shown

B. Find the area when X=4.5 in

ILL MARK BRAINLIST !!! SHOW WORK

A.

B.

Step-by-step explanation:

A.

Where,

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

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

3/4 ÷ 3/4

step-by-step explanation:

basically divide any proper fraction with itself to fit the criteria.

so if we are using 3/4, then:

3/4 ÷ 3/4 = 1

so 1 is the quotient.

and the numerators for both these fractions is 3.   and if we divide the numerators:

3 ÷ 3 = 1

we see that quotient is equal to our original quotient as well.

40 x 50 = 2000
