Answer:
Step-by-step explanation:
A 4-ft pole casts a 5-ft shadow, so an 8-ft hedge casts a 10-ft shadow. Tge hedges must be 10 ft from the garden.
bearing in mind that, whenever we have an absolute value expression, is in effect a piece-wise function with a positive and a negative version of the expression, so
-12+3b-1=-5-b
Combine like terms to get:
3b-13=-5-b
Add 13 to both sides:
3b= 8-b
Add b to both sides:
4b=8
Divide both sides by 4:
4b/4=8/4
b=2
Final answer
b=2
