Answer: 16x - 4
Explanation: Since all of the sides of a square are equal in length by definition, the perimeter of a square is 4 times its side length. 4(4x-1) is 16x - 4 when simplified.
Answer:
D. v=<20, 52>
Step-by-step explanation:
Vector u can be written in component form by subtracting its initial point from its terminal point:
u = (5, -4) -(15, 22) = <-10, -26>
We are told that v = -2u, so ...
v = -2<-10, -26> = <20, 52>
_____
Multiplying a vector by -1 reverses its direction; multiplying it by some factor k changes its magnitude by a factor of k. To reverse the direction and double the magnitude, we can multiply u by -2.
Surface area is the sum of the areas of each side of a three dimensional object.
There are two sides that are 11x9, two sides that are 9x3, and two sides that are 11x3.
So the surface area is:
2(11)(8)+2(9)(3)+2(11)(3) = 296 ft^2
