Can someone pls show how to do this is with explanation

yes

Step-by-step explanation:

-3m+2=20

-3m=20-2

-3m=18

m=-6

The answer is true

Step-by-step explanation:

1. Substitute -6 where you see M.

We do this is because M is equal to -6. So where we see another M, we automatically know that it is -6.

2. Rewrite the equation.

It should go from (-3m+2=20) to {-3 (-6)+2=20}

3. Solve it

-3 times -6 equals positive 18. In multiplication, a negative times a negative equals a positive. Then add the 2 and you get 20. So our answer is true.

Here's a visual walk through.

-3m+2= 20          m=-6

-3(-6)+2=20

-3(-6)= 18

18+2=20  

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.

step-by-step explanation:

because where the point where the 2 lines intersect is (3,-1) the x value is 3
