We know the perimeter of a triangle is the sum of all the sides( two legs and one hypotenuse).
By pythagoras we know that

and the perimeter is
.
Since P=24 and a=6 we have these equations:

From the last equation we have
. Replace h in the first equation we get that


and h=18-8=10
The First one (A) because it’s a straight line
Answer:
11
Step-by-step explanation:
<u><em>SUBTRACT</em></u>
Answer:
23 over 15 or 1.533
Step-by-step explanation:
Group like terms:
1+(3/5+-1/15)
Find LCD:
1+9/15+-1/15
Combine numerators:
15/15+8/15
And you get 23/15
Simplified:1 8/15
Decimal: 1.533
2x^2 + 5x + 2 = 0
(x + 2)(2x + 1) = 0
x = -2 x = - 1/2
Letter C
