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

Answer:
y = 4x+48
Step-by-step explanation:
Slope intercept form is y=mx+b. We already know the value for m(4), so we can plug in the x and y coordinates for x and y in the equation. This gives us 12=4(-9)+b. Solve for b to get 48
Answer:
130.5
Step-by-step explanation:
similar shapes have proportional sides so divide 18/27 to get the proportion then multiply each side of the smaller polygon by the proportion to get the sides for the larger polygon and add the larger polygons sides together.
