Answer:
The value of x is 6
Step-by-step explanation:
The perimeter of an equilateral triangle is P = 3 × S, where S is the length of each side
∵ The perimeter of an equilateral triangle is 63 inches
∴ P = 63 inches
→ By using the rule of the perimeter above
∵ P = 3 × S
→ Equate the right sides of P
∴ 3 × S = 63
→ Divide both sides by 3
∴ S = 21 inches
∴ The length of each side is 21 inches
∵ The length of each side is (4x - 3)
→ Equate (4x - 3) by the length of each side
∴ 4x - 3 = 21
→ Add 3 to both sides
∵ 4x - 3 + 3 = 21 + 3
∴ 4x = 24
→ Divide both sides by 4 to find x
∴ x = 6
∴ The value of x is 6
Option C is correct.
Step-by-step explanation:
We need to identify the composite numbers from the given options
<u>Composite Numbers</u>
A number is composite number if it has factors other than 1 and the number itself i.e the number is not prime.
The numbers 19, 23 and 37 are prime numbers because they have factors 1 and the number itself while 33 is composite number because it has factors 1,3,11,33.
So, Option C is correct.

30+11 inches = 47 inches
Answer:
300 %
Step-by-step explanation:
Length of the larger cube =4 cm
So volume 
Length of the smaller cube = 1 cm
Volume of the smaller cube 
So total number of smaller cube 
Surface area of the larger cube 
Surface area of the 64 smaller cube 
So percentage increase in surface area 
%
