Both sides should be the same length..
Since we know that BC = 23 you need to find the value of x and put it in the formula.
23 = 2x+7
16 = 2x
x = 8
4x + 1 + 4(8) + 1 = 33 units
Answer:

Step-by-step explanation:
It is given that,
V = bdt i.e. V is equal to the product of b, d and t
We need to find the formula for d.
Dividing both sides of the given expression by bt
So,

Hence,
is the value of d.
√84= √4•√21= final answer is
±2√21
