Add them together:

Brandon's backpack weighs = 3140 grams.
We know, 1000 grams in a kilogram.
Therefore, 3140 grams = 3000 grams + 140 grams = 3 kilogram 140 grams.
Brandon weighs(without backpack) = 22 kg 610 grams more than his backpack.
More than pharse represents addition.
22 kg 610 grams more than backpack weighs = 22 kg 610 grams + 3 Kg 140 = 25 Kg 750 grams.
Therefore, Brandon weighs(without backpack) = 25 Kg 750 grams.
Total weight of Brandon weighs and backpack weighs = Brandon weighs(without backpack) + backpack weighs.
= 25 Kg 750 grams + 3 Kg 140 grams
= 28 Kg 890 grams.
Therefore, Brandon got 28 Kg 890 grams on a scale when wearing his backpack.
Answer:
Domain [-4 , +∞)
Range [0 , +∞)
Step-by-step explanation:
the function g such that g(x)=√(x+4) ,is defined
for the values of x that verify :
x + 4 ≥ 0
⇔ x ≥ -4
Then
The domain of g is [-4 , +∞)
………………………………………………
Let x ∈ [-4 , +∞)
then x ≥ -4
then x + 4 ≥ 0
then g(x) = √(x+4) ≥ 0
Therefore, we can affirm that the range of g is [0 , +∞)
