Verify whether or not the algebraic expressions are equivalent for m = 4. Explain your answer. 2m + 5 + m – 4

– 5m – 4 + 8m + 5

yes

Step-by-step explanation:

2m+5+m-4= -5m-4-8M+5

(2m+m)+(5-4) =( 5m+8m)+(-4+5)--->combine like terms

3m+1=3m+1

3m-(3m)+1=3m-(3m)+1 subtracting 3m from both sides

1=1

1-1 = 1-1

0=0

all real numbers are solutions, so therefore m is equivalent to 4

Sample Response: Yes, the expressions are equivalent, because when substituting the value, 4, for the variable in both expressions, they both simplify to the same value, 13.

I took the same question!!! Hope this helps :D

2? if not the correct answer you might need to provide more information

step-by-step explanation:

v = 1/3 a^2h

step-by-step explanation:

if the height is 57.7cm and the height of the slant edge is 18.2cm, then the volume is 1/3 a^2h.
