If you have to write the equation then it would be "5k + 6.7"
Step-by-step explanation:
1 act like the decimals aren't there then put 50:1 on the outside and 6630 on the inside and divide like normal
Step-by-step explanation:
- The area of the blue square will always equal the sum of the area of the orange and red rectangles
The pythagorian theorem:
a²+b² = c²
now let a be the side of the red triangle and b the side of the orange one
so a² is the area of the red triangle and b² is the area of the orange one
Let c be the side of the blue rectangle
so c² is the area of it
then what we concluded is right
- the hypotenuse is the blue side since it is the larger one
