Answer:
-6/5
Step-by-step explanation:
-17-1 = -18=-6
17-2= 15=5
Answer:
sss is all sides are the same length, in the same order, and if they both have those side they are congruent. sas is two sides that are connected by an angle, and if the sides connected by that angle match the other triangle then they will be congruent
Step-by-step explanation:
Answer:
252 inches
Step-by-step explanation:
Alright, so we've got to find the surface area of both of the rectangular prisms and add them together.
We can use the equation 2(2l+hl+hw)
Plug the numbers in for the first box and you get 62 for the surface area.
Do the same for the second, you should get 190.
Now we just need to add the two together. 190+62= 252
The surface is parameterized by
and the normal to the surface is given by the cross product of the partial derivatives of 
:
It looks like you're given
Then the normal vector is
Now, the point (2, 2, 0) corresponds to u and v such that
and solving gives 
, so the normal vector at the point we care about is
Then the equation of the tangent plane is
4x-3=12
add 3
4x=15
divide 4
x=15/4
x=12/4+3/4
x=3+3/4
x=3 and 3/4
answer is 3 and 3/4
