I answered the last post, the third option is correct
The answer is II and III, which is the last choice from above. This is because the symbol "less than (or equal to)" indicated a conjunction, which means we have to take into account that the absolute value can be less than or equal to 15, and greater than or equal to -15. This solution set falls in between the two values, hence, the conjunction.
<span>By by pythagorean theorem
12 (squared) + r (</span>squared) = (8+r) squared<span>
so 144 + r ( </span>squared) = 64 + r (squared)<span> +16r
so solving for r:
144 -64 = r </span>squared –r squared<span> + 16r
80 = 16r
so r = 80/16= 5
the second is the same
21 </span>squared + r squared = (9 + r ) squared<span>
441 + r </span>squared = 81 + r squared<span> + 18r
441 – 81 = r </span>squared – r <span>squared</span><span> + 18r
r = 360/18 = 20</span>

Step-by-step explanation:
WHats the question here bud
Answer:
solve for x
4x-6=26
4x=26+6
x=32/4
x=8
area of rectangle=l*b
=26*14
=364
area of triangle=b*h/2
=18.4*20.4/2
=375.36/2
=187.68 m^2
for another side of a triangle
(18.4)^2+(20.4)^2=c^2
338.56+416.16=c^2
=c
27.47=c
27.5=c
now, perimeter of triangle=a+b+c
=27.5+18.4+20.4
=66.3 m^2
radius=diameter/2
=26/2
=13 ft
diameter=26 ft
circumference=2πr
=2*3.14*13
=81.64
Area of a circle=π
=3.14*(13)^2
=3.14*169
=530.66 ft^2
