Which of the following is a solution of the equation -5x + 2 = -13: answers: x=-9, x=75 x=3 x=-3

x= 3

Step-by-step explanation:

1. -5(3) + 2 = -13      

2. -15 + 2 = -13         A positive times a negative will always equal a negative

3. -13 = -13         Whenever you add anything to a negative number, the                    

                           number becomes smaller  

                     Ex:  -10, -9, -8, -7, -6, -5, -4, -3, -2, -1, 0, 1, 2, 3,

                           Although the number itself becomes smaller, its value    

                            becomes bigger      

Hope this helps.

the fist one is not equalvalent but i think th second one isand the third isnt definetly or the last one is i think. hope this !

step-by-step explanation:

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.
