There are 4 lateral faces that are triangles. Each triangle is: A = 
A =
= 176
There is one base that is a square. A = L x W
A = 16 x 16
= 256
Surface area = 256 + 4(176)
= 256 + 704
= 960

Answer:
d) intersecting, but not perpendicular lines
Step-by-step explanation:
Changing the sign of one of the variable terms causes the line to be reflected across one of the axes. The slope is the opposite of what it was. Since the original slope was not 1 or -1, the resulting line is not perpendicular to it. Lines with different slopes will be intersecting.
The two lines are intersecting, but not perpendicular.
Answer:
Yes, vectors u and v are equal.
Step-by-step explanation:
We need to check whether vectors u and v are equal or not.
If the initial point is and terminal point is
, then the vector is
Vector v with an initial point of (-5,22) and a terminal point of (20,60).
..... (1)
Vector u with an initial point of (50,120) and a terminal point of (75,158).
.... (2)
From (1) and (2) we get
Therefore, vectors u and v are equal.
