Answer:
59.15 in^2
Step-by-step explanation:
Using Heron's formula
semiperimeter , s = 1/2 ( 28.8+18+12) = 29.4
Area = sqrt ( 29.4(29.4-28.8)(29.4-18)(29.4-12) ) = 59.15 in^2
Answer:
Step-by-step explanation:
Ive already explained this somebody else asked if you find it you will have the answer
Answer:
C
Step-by-step explanation:
switch 5 to the other part of the equation and do 5+3. Now you will have -2a=8 affectively -1a =4+
Answer:
No
Step-by-step explanation:
Because in the number 15.8, it is equal to 15.80. 80 is more than 17.
Let the short side be x.
2x+(x+12)+(3x-9)=117
6x-3=117
6x=120
x=120/6=20
Each of the short sides is 20, the third side is 32, and the last side is 51. Hope this helped!
