3x+3=90
subtract 3 from both sides
3x=87
divide both sides by 3
x=29
To find IJ, plug in the x value
x+8+x-9
29+8+29-9
57=IJ
Figure A best represents it because if you add 576 and 49 you get 625, which shows the theorem of a^2+b^2=c^2.
Hello,
Let's be x the length of the 3 side (9,x,23) ==>x>0
Using inequality triangular:
9<x+23==>x>9-23==>x>-14 (done)
x<9+23==>x<32
23<x+9==>x>14
SO 14<x<32
Answer: 408.2 ft^2
Step-by-step explanation:
A=2πrh+2πr2
A=2(3.14)(5)(8)+2(3.14)(5)^2
A=6.28*40+6.28*25
A=251.2+157
A=408.2 ft^2
