Hello again! So what you have to do ir add up all of the weights to find out how much Duane's backpack weighs in total. Before you do that, convert 2 1/4 to ounces which equals 36 ounces and convert 3 3/4 to ounces which equals 60 ounces. Add them all up and you get 176 ounces. Hope I helped again!

Answer:

-\infty

Step-by-step explanation:

f(x)=\frac{-8x^4+3x^2-7x}{4x^2-4}=\frac{-8x^2+3-7/x}{4-4/x^2}

As x approaches -\infty, f(x) will tend to -\infty

Can anyone help me, i will give brainiest.

Answer: ∠DOB: 48°

Step-by-step explanation:

1. we need an equation first. the sum of all angles (108°, n°, 2n°) is equal to 180°. we can depict this with the equation: 108°+2n°+n°=180°

2. now we can solve for the missing variable, n.

108°+3n°=180° → subtract both sides by → 3n°=72° → divide both sides by 3 → n=24°

3. now that we know that n=24°, we can solve the value of ∠DOB. we can see that ∠DOB is 2n° which we just plug the number we got for n into the equation. 2*24=48° meaning ∠DOB is 48°

hope this heped! ♡
