Formula of square area
a = s²
thus, area of the first square could be written as s₁² and area of the second square could be written as s₂²
First, write an expression in the form of equation system
An expression for "The combined area of two squares is 45 square centimeters" is:
⇒ s₁² + s₂² = 45 <em>(first equation)</em>
An expression for "Each side of one square is twice as long as side of the other" is:
⇒ s₁ = 2s₂ <em>(second equation)</em>
Second, solve the equation system by substitution method.
⇒ We could substitute 2s₂ to s₁ (second equation) in the first equation in order to find the value of s₂
s₁² + s₂² = 45
(2s₂)² + s₂² = 45
(2²)(s₂)² + s₂² = 45
4s₂² + s₂² = 45
5s₂² = 45
s₂² = 45/5
s₂² = 9
s₂² = 3²
s₂ = 3
⇒ Substitute the value of s₂ to the second equation in order to find the value of s₁
s₁ = 2s₂
s₁ = 2(3)
s₁ = 6
The length of each side of the larger square is 6 centimeters

i wanna say 30 cm?
Step-by-step explanation:
The time length for a sign to travel from new york to Miami is 0.089 seconds.
We understand the speed of mild in miles per 2nd is 186,000.
the rate of smartphone signal is 2/3rd is =2/3rd of 186,000
= 124,000 miles in line with 2nd
Distance among Miami and new york is given to be 1100 miles.
So, the time required to journey the phone signal from new york city to Miami is = distance ÷ speed
= 1100 ÷ 124,000
=0.089 seconds
Time taken via the telephone sign from Miami to new york is 0.089 seconds.
