<h3>
Answer: A) Square meters</h3>
Explanation:
Imagine that a parent bought a basketball for their son or daughter. If they wrapped the ball with wrapping paper, then that wrapping paper can be unwrapped to form a flat sheet. So the area of the sheet corresponds directly to the surface area. If the sheet is say 1 meter by 1 meter, then the area is 1*1 = 1 square meter. We can abbreviate "square meters" into "meter^2" or "m^2".
100-10=90
450=90% of original find 100%
divide by 9
50=10%
times 10
500=100%
origianl price=$500 (this is the hack way that only works with nice numbers)
Answer:
Step-by-step explanation:
If the smallest number is 'x', then the other number = x +1
x*(x+1)= 420
Use distributive property
x*x + x*1 = 420
x² + x - 420 =0 ------> this is the required quadratic equation.
It would be c 15/22 as the answer
