The answer is… 2 - 5 = -3
This is simple math so regularly since you will get a negative if it is puted as 2 - 5. So you might as well do the simple math 2 - 5, than as soon as you get your answer than just put a negative sign since it isn’t in the basic number scale, but instead on the negative number scale.

Answer: -3

Step-by-step explanation: well there is a pretty easy explanation for this because what you pretty much do is you put the answer around by doing 5-2 and just put a negative since the smaller number is in the front.

- What is the area of the figure below? Use 3.14<br> for T.<br> 7 cm<br> 22 cm<br> 18 cm

Answer: $\Large\boxed{Total~area=586.17~cm^2}$

Step-by-step explanation:

<h2>PART I: Find the area of the triangle</h2>

<u>Given information</u>

$Height=7~cm$

$Base=18~cm$

<u>Given formula</u>

$A=b\times h\times\dfrac{1}{2}$

$A=Area\\b=base\\h=height\\$

<u />

<u>Substitute values into the formula</u>

$A=(7)\times (18)\times\dfrac{1}{2}$

<u>Simplify by multiplication</u>

$A=(7)\times 9$

$A=63~cm^2$

<h2>PART II: Find the area of the rectangle</h2>

<u>Given information</u>

$Height = 18~cm$

$Base=22~cm$

<u>Given formula</u>

$A=b\times h$

$A=Area\\b=base\\h=height\\$

<u />

<u>Substitute values into the formula</u>

$A=(22)\times (18)$

<u>Simplify by multiplication</u>

$A=396~cm^2$

<h2>PART III: Find the area of the half-circle</h2>

<u>Given information</u>

Diameter = 18 cm

<u>Given formula</u>

$A=(\dfrac{d}{2} )^2\times \pi \div2$

$A=Area\\d=diameter$

<u>Substitute values into the formula</u>

$A=(\dfrac{18}{2} )^2\times (3.14) \div2$

<u>Simplify the fraction</u>

$A=(9 )^2\times (3.14) \div2$

<u>Simplify the exponents</u>

$A=81\times (3.14) \div2$

<u>Simplify by multiplication</u>

$A=254.34\div2$

<u>Simplify by division</u>

$A=127.17~cm^2$

<h2>PART IV: Find the total area</h2>

<u>Given formula</u>

$Total~area=Triangle+Rectangle+circle~(half)$

<u>Substitute values into the formula</u>

$Total~area=(63)+(396)+(127.17)$

<u>Simplify by addition</u>

$Total~area=459+(127.17)$

$\Large\boxed{Total~area=586.17~cm^2}$

Hope this helps!! :)
