Answer:
A=10 cm
B=5 cm
Area of square = 25 cm
Step-by-step explanation:
Since that is an equilateral triangle based off the fact that all the sides are the same variable (a) then that means 30 divided by 3 which equals 10. So now we know that a = 10. Lets input that information for the rectangle. Since there are 2 a's that equals 20 and the perimeter is 30 so b has to be 5 since 5 times 2 is 10 plus 20 equals 30. so now we know that a=10 and b=5 so our squares sides are all 5. The area of the square is 25
The only true inequality is <u>-3 1/2 > -4.5</u>
Answer:
I believe the answer is A
Step-by-step explanation:
1. Find the number that is supposed to be within the ?
2. Place that number (which in this case it is 2.02) inside of each ? mark and solve to see if that answer works.
3. In the end, A is the only one where the ? solution works.
