Answer:
x=6
Step-by-step explanation:
1 Add 44 to both sides.
2x=8+42x=8+4
2 Simplify 8+48+4 to 1212.
2x=122x=12
3 Divide both sides by 22.
x=\frac{12}{2}x=
2
12
4 Simplify \frac{12}{2}
2
12
to 66.
x=6x=6
P=2x+2y, y=(p-2x)/2
a=xy, using y found above in this equation gives you:
a=(px-2x^2)/2 we are told a=12 and p=16 so
12=(16x-2x^2)/2
24=16x-2x^2
2x^2-16x+24=0
2x^2-12x-4x+24=0
2x(x-6)-4(x-6)=0
(2x-4)(x-6)=0
2(x-2)(x-6)=0
So the table is 2 ft by 6 ft.
All are relations except for relation 3
Answer:
x=67
y=36
Step-by-step explanation:
x+y=103
2y=x+5
It's a computation. It would be 8!/3!(8-3)! If my memory serves me correctly.
