Answer:
4.39x15.37=67.4743. Rounded to the nearest whole number is 67.
Step-by-step explanation:
First solve for one variable
solve for a in second eqatn
minus 3x both sides
a=17-3x
sub 17-3x for a in first equaiton
2(17-3x)+2x=18
34-6x+2x=18
34-4x=18
minus 34 both sides
-4x=-16
divide both sides by -4
x=4
sub back
a=17-3x
a=17-3(4)
a=17-12
a=5
a is 5
x=4
WORK SECTION (without thoughts)
2a+2x=18 to a+x=9
a+3x=17
a=17-3x
(17-3x)+x=9
17-2x=9
-2x=-8
x=4
a=17-3(4)
a=17-12
a=5
x=4
a=5
Is this what you need 4x/ [5-(2x/3)] ?
If yes, then 4x/[(15-2x)/3] = 4x•3/(15-2x) = 12x/(-2x+15)
R = 3 so d = 2r = 2 x 3 = 6
C = pi d,
semi-circle C= 1/2 pi d = 1/2 (3.14)(6) = 9.42
P of rectangle = 2(4+6) = 2(10) = 20
so P of figure = 20 + 9.42 = 29.42 m
answer
29.42 m
