Answer:
part a. A
part b. x + 6
part c. (4x – 1)(3x + 6)
Step-by-step explanation:
width + x + x = 3x + 6
width = 3x + 6 – x – x /answer for part a/
width = x + 6 /answer for part b/
Area = (length)(width) = (4x – 1)(3x +6) /part c/
Answer:
195
Step-by-step explanation:
If there are x boys, then there are x+26 girls. Hence, we write the equation,
x+(x+26)=364
Solve for x:
2x+26=364
2x-338
x=169
So there are 169+26 =195 girls
Y = x/5280
converting miles to feet would be x=5280y
