A.) find the product (-1.15) x 3.2 b.) explain in words how you determined the sign of your answer.

(A)

we are given

(-1.15) x 3.2

Since, sign of 1.15 is negative

and sign of 3.2 is positive

so, we put negative sign in front

now, we can multiply them

and we get

.............Answer

(B)

Suppose, we are given product of two numbers 'a' and 'b'

so, we use this property

case-1: When both positive , then we put positive in front

case-2: When both negative  , then we put positive in front

case-3: When first is  negative and second is positive   , then we put negative  in front

case-4: When first is  positive and second is negative    , then we put negative  in front

341

step-by-step explanation:

all you have to do is 9x31 (which equals 279) and then 20x31 (which equals 620). then you have to subtract. 620-279=341.

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

step-by-step explanation:

given   that triangle lno is congruent to triangle lnm.

we have to fill up the blanks in the given question.

according to above order of congruency   kept in mind we can say that

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

ln ≅ ln due to common in both.

hence, by sas congruency,

the side angle side rule   states that if two sides and the included angle of one triangle are congruent to another triangle, then these two triangles are congruent.
