The triangle is an acute triangle because of the Pythagorean Formula for acute triangles.
Answer:
Parallel lines
Step-by-step explanation:
y = 2.5x + 3 (slope= 2.5= 5/2)
y = 5/2x (slope=5/2)
If you made $7 an hour and worked for 40 hours, every day for a year, you would make $14,560 a year and about $1,213.33 a month.
Because 7 x 40 = 280 (which is how much money you make a week.)
And 280 x 52 = 14,560 (because you would work for 52 weeks).
I hope this helped! Good luck and have a great night!
Answer:
2a +2b +4
Step-by-step explanation:
The perimeter is the sum of the lengths of the three sides. If x represents the length of the third side, then ...
(3a +8) +(5a +b) +x = (10a +3b +12)
Subtracting from the equation everything on the left side that is not x, we get ...
x = (10a +3b +12) -(3a +8) -(5a +b)
= a(10 -3 -5) +b(3 -1) +(12 -8)
= 2a +2b +4
The length of the third side is 2a +2b +4.
