exponents not included in this problem
multiplication
divison
addition not included in this problem

that leaves multiplication as our first priority, division as our second.

$12 * 4 = 48\\48 * 3 = 144\\144 * 5 = 720\\solve~2 * 6\\2 * 6 = 12\\now~resume\\12 / 720 = 60$

Write the next 4 terms in each pattern. Write each pattern rule. a) 12, 36, 84, 180, 372... Pattern Rule: b) 8, 12, 24, 60, 168.

tekilochka [14]

For a) the pattern rule goes 12+(12x2)=36 36+(12x4)=84

So the pattern rule is double the number and then times it by twelve to get to the next answer

The perimeter of a square must be greater than 102 inches but less than 138 inches. Find the range of possible side lengths that

liberstina [14]

Answer:

s ∈ (25.5,34.5)

''s'' is in inches unit

s ∈ IR

Step-by-step explanation:

We know that the perimeter of a square is $P=4s$

Where P is the perimeter and s is the length of a side.

We want the perimeter to be greater than 102 inches but less than 138 inches.

We can write :

102 inches < P < 138 inches

If we replace P = 4s in the expression :

102 inches < 4s < 138 inches

Dividing by ''4''

25.5 inches < s < 34.5 inches

If we want the perimeter to be greater than 102 inches but less than 138 inches the length of a side must be greater than 25.5 inches but less than 34.5 inches.

Writing this in interval notation

s ∈ (25.5,34.5)

s ∈ IR
