Answer:
3d + 4w
Step-by-step explanation:
Since there are multiple of each variable, we can add like terms.
There are 3 d's, so adding these together gets you 3d
There are 4 w's, so this is equal to 4w.
Now, add these together to get the equivalent expression:
3d + 4w is the expression
You can use the equation rise over Run you go up 4 and over 6 and you go down 2 and over 8 (im not sure if this helps)
The answer would be False.
Perimeter of square = 4s perimiter of pentagon= 5s, i guess? its a regular one afterall 4s = P 4 (10) = p 40 = P (40 = 5s)/ 5 8 = s
Sorry I dont know how to answer the second one...
