Answer:
2/4x2/4=0.25 or 1/4
Step-by-step explanation:
8,1/8 = 65/8
5,3/4 = 23/4
Multiply 65/8 by 23/4
= 1495/32
= 46 23/32 square feet (if they want it kept as a fraction)
Or 46.72 square feet (if they want a decimal)
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: x1 = -2, x2 = 3/4
Step-by-step explanation:
4x^2 + 5x -6 = 0
4x^2 + 8x -3x -6 = 0
4x(x+2)-3(x+2)=0
(x+2)(4x-3) = 0
x+2 = 0: x = -2
4x-3 = 0: x = 3/4
