Answer:
1218
(14x25)x3=1050
because you have three sides
14x12=168 then 168+168=336
then add al together 1050+336=1 386
Answer:
3x + 4y +8 = 0
Step-by-step explanation:
(X1,Y1) = (4,0)
(X2,Y2)=(0,3)
(X3,Y3)=(0, - 2)
Slope(m)=(Y2-Y1)/(X2-X1)
= (3-0)/(0-4)
= -3/4
Equation of the line,
Y-Y3 = m(X-X3)
Y-(-2)= (-3/4) × (X-0)
Y+2= (-3/4)X
Y+2= -3X/4
4(Y+2)= -3X
4Y+8= -3X
4Y+3X+8=0 is the required equation.
Ok so first off you need to get rid of the clauses in the equation.
So 4.5 ( -4) becomes -18 and -2.5(3+28) becomes -77.5
-18 + 36 = 202 - 77.5
Now you are going to solve the equation.
18 = 122.5
Hope this helped ;),
