Answer:
Step-by-step explanation:
The given postulate If two lines intersect, then they intersect in exactly one point is true because whenever the two lines intersect they intersect at one point only and we know that a postulate is a statement that we accept without proof.
The given theorem If two distinct planes intersect, then they intersect in exactly one line is true as theorem is a statement that has been proved and it has been proved that if two distinct planes intersect, then they intersect in exactly one line.
The figures are drawn to prove them.
2x + 3x = 100
5x=100
x=100/5
x= 20
Therefore, 2x=2×20=40
3x=3×20=60

Step-by-step explanation:
subtract 45 from 75, you get 30. multiply 30 by 20, and there is your answer.
I’m not entirely sure but i think it might be s=lb^2 because the l, b, and b are all being multiplied together, and since you are multiplying and not adding the b’s, the two would go to b^2, and then you just multiply by l to get lb^2
