Answer 1

Answer: We know that the perimeter of a triangle is the sum of its three sides.

P= 3+ (2s+4)+ (4s+2)
= (2s+ 4s)+ (3+ 4+ 2) (combine like terms)
= 6s+ 9

The perimeter is 6s+9 (units)~

Answer 2

Answer: (2s+4)+(4s+2)+3=6s+9. This can also be rewritten as 3(2s+3).

Answer:

Value of 4 in 3492 > Value of 4 in 704

Step-by-step explanation:

The given two numbers are 3492 and 704

704 0 7 0 4

In 3492, 4 is at hundreds place and have a value of 4 × 100 = 400

In 704, 4 is at ones place and have a value of 4×1 = 4

Value of 4 in 3492 > Value of 4 in 704

in 3,492 the 4 has the value of 400. In 704 the 4 has the value of 4 because is in the ones place

111 2151 which one is a prime number

Answers

Neither of those numbers is a prime number, as both are divisible by 3. It's easy to tell when a number is divisible by three, because all you have to do is add up all the individual numbers that make up the big number, and if THAT number is divisible by 3, then so is the big number.

1 + 1 + 1 = 3

3 is obviously divisible by 3, so no further steps need to be taken here.

2 + 1 + 5 + 1 = 9

9 is also divisible by 3.

Neither of those numbers is prime.
