The length of each side of the larger square is 8 cm.
<u>Step-by-step explanation</u>:
Step 1 ;
- The combined area of two squares = 80 sq.cm
- The side of small square = x
- The side of larger square = 2x
Step 2 :
Area of the square = a^2
Area of small square + area of large square = 80
x^2 + (2x)^2 = 80
x^2 + 4x^2 = 80
5x^2 = 80
x^2 = 80/5
x^2 = 16
x = ±4
Step 3 :
Since length cannot be negative, the value of x= 4
∴ The length of the side of small square = 4cm
The length of the side of larger square = 2x = 8cm
Answer:
7/8 miles
Step-by-step explanation:
Given data
From her house to the park= 1/4 miles
Around the park = 3/8 miles
back home= 1/4 miles
Total distance= 1/4+3/8+1/4
LCM= 8
=2+3+2/8
=7/8 miles
If 7x+3=24, that means x would be 3 so if you take 5-4x then that would be -7.
(v-4t)(v+nt)
=v^2+vnt-4tv-4nt^2
