If I'm understanding your question, the drawing is 10cm and for every 10cm, the drawing is etched 1mm. This means that no matter how big the drawing gets, the actual object will always be bigger since it's 10cm larger always than the drawing. Hope this helped!
Answer:area of big square is 9x6 = 54 sq ft. Area of smaller square is 6x4 = 24 square feet. So if you throw a dart, you have a 24/54 or 4/9 chance of hitting the shaded spot.
Step-by-step explanation:
8 more that is 8+
four times a number is 4*X
is -12: =-12
8+4*X=-12
to solve this equation subtract 8 from both sides.
8+4*X=-12
-8 -8
4*X=-20
divide by 4 on both sides.
X=-5
The answer to 36 + 54 is 90
