Answer:
x={7,3}
Step-by-step explanation:
x^2-2x+9+12=0
x^2-2x+21=0
(x-7)(x-3)=0
x-7=0
x=7
x-3=0
x=3
so
x={7,4}
Answer:
95 cm^2
Step-by-step explanation:
perimeter(p)=39cm
L=3x-1
B=2x+3
Now,
p=2(l+b)
39=2(3x-1+2x+3)
39=6x-2+4x+6
39=10x+4
39-4=10x
x=35/10
x=3.5
Putting the value of x
L=3x-1; =3×3.5-1; =10.5-1; =9.5cm
B =2x+3; =2×3.5+3; =7+3; =10cm
Again,
A= L×B
=9.5×10
=95cm^2
The answer will be p = i/rt instead. You just flipped the process by mistake :)
