Answer:
202.5cm^2
Step-by-step explanation:
P=2l+2w
63=2(9)+2w
63=18+2w
63-18=2w
45=2w
divide both sides by 2
22.5=w
check:
P=2(9)+2(22.5)
=18+45
=63
Area=l×w
=22.5×9
=202.5cm²
The solution is in parenthesis, so this means the numbers are included in the answer. Since the first number is 2, 2 is a possible answer so the circle at positive two would be solid.
The other solution is infinity, so the answers are any number to the right of the 2 on the number line.
This makes the answer: A solid circle appears at positive 2. The number line is shaded between positive 2 and positive 5.
Well this question is actually a piece of cake. Just pick your favorite number. Multiply it by 10. Then do whatever operation you want with the 2,300. For the exponent part of this. Lets say we do it this way y times z equals 2,300. Exponents are letters used in mathematical terms. So any letter can be used to represent any number.
