64 is the answer, as all you need to figure out is the length, and width, and multiply them together. Or, just count each unit inside the shape.
<span>Write an expression for the total cost of the tools.
</span>
total cost = <span>$11.79 (4) + </span>$6.65 (7)
<span>Then find the total cost.
</span>total cost = $11.79 (4) + $6.65 (7)
total cost = $47.16 + $46.55 = $93.71
Answer:

Step-by-step explanation:
There are exponent rules I posted above that are being used here.
We have (3^-6)^-5
Since we have a power times a power, we multiply 6 and 5 to get -30. Look at the first example in the photo.
So, we're left with 3^-30.
If you look at the photo, there's a rule for negative exponents.
Take the inverse of the base number, so 3 in this case:
1 / 3
and then make the exponent positive after taking the inverse.
So, we should get 1 / 3^30
Hope this helps!
D is a notation for differential. There is a d2 in your formula because in the numerator there are two differentials. The formula is thus the second derivative of a function with respect to two variables.
