Formula for are of a rectangle:
        A =L * W
1st isolate W
   147 = 3W * W
   147 = 3W^2
divide 147 by the by 3 on bot sides
    29 = W^2
get ride of the square by square rooting on both sides
     7 = W

2nd find the perimeter
    P = 2(7) + 2(21)
    P = 14 + 42
    P = 56

If u-ai + bj and v-ci + dj are vectors, then which of the following statements is not true?
alukav5142 [94]

Answer:

Option C

Step-by-step explanation:

Given that u-ai + bj and v-ci + dj are vectors

We have dot product

u.v = (ai+bj).(ci+dj) hence inner product of u and v.  So option a is true

The dot product of u and v is a scalar is true because dot product is always a scalar

The dot product of u and v is a vector. is false because dot product is only a scalar and has no direction and hence cannot be a vector

The dot product of u and v is given by the expression ac+bd

True because we multiply corresponding i components and j components and add.

So only C is not true.
