I’m not understanding how you can solve for this?

-1/12

Step-by-step explanation:

You have to substitute the given values of x and y into the expression 4xy². So now the expression would look like this: 4×-1/3×1/4².

Now just simplify from there.

4×-1/3×1/16

-4/3x1/16

-4×1/3×16

-4/48

-1/12

Not sure if my answer is really right but hope this helped nudge you in the right direction

m∠a is 90°

m∠b is 40°

168

step-by-step explanation:

first off, we know that he drove 3.5 hours at a rate of 48 mph.

knowing that, we want to see how many miles he drove all-together.

in this case, we can just multiply 48 by 3.5.

48 * 3.5 = 168
