The area of the triangle can be calculated through the equation,
             A = sqrt ((s)(s - a)(s - b)(s - c))
where A is area, s is the semiperimeter ((a + b + c)/2), a, b, and c are the sides given above.

The presented equation above is the Heron's formula.

Substituting the known values,
             s = (8.7 + 10.1 + 9.8) / 2
              s = 14.3

    A = sqrt ((14.3)(14.3 - 8.7)(14.3 - 10.1)(14.3 - 9.8))
           <em>A = 38.9 units squared

</em>
Thus, the answer to this item is not among the choices. <em>

HES<br> LO)<br> What is the solution to the equation -(5-(a+1)) = 9-(5-(2-3))?<br> TESI
diamong [38]

Solution for given equation -(5-(a+1)) = 9-(5-(2-3)) is a = 7

<u>Solution: </u>

Need to determine solution of following equation’

-(5-(a+1)) = 9-(5-(2-3))

Means need to solve the above equation for "a"

On solving operation in most internal bracket we get  

-(5-(a+1)) = 9- ( 5 – ( -1))  

On opening inside brackets we get,

-(5 – a – 1 ) = 9 – ( 5 +1 )  

On solving remaining brackets we get

-5 + a + 1 = 9 – 6

=> a – 4 = 3

=> a = 4 + 3 = 7

=> a = 7

Hence solution for given equation -(5-(a+1)) = 9-(5-(2-3)) is a = 7

The number w and 0.8 are additive inverses.
umka2103 [35]

Since, the number w and 0.8 are additive inverses.

A number 'a' is said to have an additive inverse '-a' if "a+ (-a)= 0".

Since, 'w' and '0.8' are additive inverses of each other such that w + 0.8 = 0

Therefore, the value of 'w' should be '-0.8' so that -0.8 + 0.8 = 0.

So, the value of 'w' is =0.8

Now, Refer to the attached image which represents the position of 0.8 , w ( that is -0.8) and the sum of 0.8 and w.

Sum of 0.8 and w = 0.8 + w

= 0.8 +(-0.8)

= 0.
