Alejandro is correct because you do not need to add another number to 76.518, as Jiro did, but you need to round it to the nearest tenth.
Glad I could help, and good luck!
x=3y
Switch sides
3y=X
Divide 3 both sides to get
T= x/3
The answer is 3x-14 . . . . . . . . . . . .
The perimeter should be 11, since 33 divided by 3 is eleven.
Answer:
b=5V2
Step-by-step explanation:
Area =31 1/4 = b*12.5 sin45/2=b*12.5*V2/2* 1/2=12.5V2/4 *b
(31*4+1)/4=125/4
so 125/4= 12.5V2*b/4
12.5V2*b=125
b=125/12.5V2=10/V2=10V2/2=5V2
