Construct a matrix that triples the height, width, and length of an objective in 3d

Step-by-step explanation:

Our dimension vector is:

We need a matrix that returns another 3x1 vector, where only each component is 3 times the original value.

Let's see for x:

if

then:

a*x+b*y+c*z=3*x then, b=c=0 and a=3

d*x+e*y+f*z=3*y then, d,f=0 and e=3

g*x+h*y+i*z=3*z then g,h=0 and i=3

answer: the distance

step-by-step explanation:

to calculate the distance d of a line segment with endpoints (x1, y1) and (x2, y2) use the formula d (x2 x1)2 (y2 y1)2. to calculate the midpoint of a line segment with endpoints (x1, y1) and (x2, y2) use the formula

the area of the rectangle is 35units^2.

step-by-step explanation:

graph it and find the distance.

it is a 5*7 rectangle.

therefore the area is 35units^2.
