We never did inverse propositions when I had logic. The inverse of
if P then Q
is the proposition
if not P then not Q
We have
P: A triangle has three congruent angles
Q: it is an equilangular triangle
The inverse is thus if not P then not Q
If a triangle does not have three congruent angles then it is not an equilangular triangle.
Answer: First choice
The reason we didn't do inverses is it has the same truth value as the converse; the inverse is the contrapositive of the converse.

Step-by-step explanation:
Two lines are parallel if they have the same slope. Two parallel lines never intersect.
Answer:
Company B is the better deal. Diego will save $31.5.
Step-by-step explanation:
First, find the area of the rectangle: 45*30=1350 sq.ft.
Next, find out how much it will cost for Company A: $3.9 for 2 x 5 ft (10 sq.ft)
Divide 1350 by 10 to see how many of their sod rolls will fit into his yard=135.
Multiply $3.9 by 135=526.5$
Do the same with Company B: $150 for 450 sq.ft plus $45 delivery.
Dived 1350 by 450 to see how many rolls= 3
Multiply $150 by 3= $450, then add $45= $495
Subtract Company B's $495 from Company A's $526.5= $31.5 <-how much Diego saved.

Try it out
It is given in the question that,
The speed of sound is 1088 feet per second at sea level at 32° f.
It means , in one second, sound travels a distance of 1088 feet.
And we have to find the distance travelled by sound after 8 seconds.
Therefore, after 8 seconds, the sound travels
