Answer:
b. false
Step-by-step explanation:
If and are rational expressions, then x = .
In these problems, we need to cross multiply to solve them.
2in 3 in
______ = _____
16feet h feet
To cross multiply, we multiply the terms diagonal from each other. So it would be '2*h' and '16*3'
2h=16*3
2h=48
divide both sides by 2
h=24ft
Same thing for the other problems, we just cross multiply
1/4*32=4*b
8=4*b
divide both sides by 4
2=b
and for the last one, I honestly have no clue what the square shape is supposed to mean...
