Answer:
Equation C: 5/8x + 2..5 = 3/8x + 1.5 + 1/4x
Step-by-step explanation:
Let us go through each of the equations one by one.
Equation A: 
This simplifies to
which has infinitely many solutions.
Equation B: 
this simplifies to
which is exactly one solution.
Equation C: 
this simplifies to
There's no way this is going to be possible; this equation has no solutions.
Equation D: 
this gives
which is exactly one solution.
Thus we see that it is equation C that has no solutions.
Area of square =6*6= 36 cm^2
Area of trapezoid =1/2( base1+base2)*height
base 1=7
base2=21-6=15
height=6
Area of trapezoid =1/2( 7+15)*6= 66
whole area = area of square + area of trapezoid= 36+66=102
Answer 102
Answer:
I need more context ,like the graph to figure this out.
Step-by-step explanation:
I=400(0.04)(5)
Interest is 80 dollars of interest
400+80=480

Answer:
x=4
Step-by-step explanation:
√x+12=x
x+12=x2(Square both sides)
x+12=x2
x+12−x2=x2−x2(Subtract x^2 from both sides)
−x2+x+12=0
(−x−3)(x−4)=0(Factor left side of equation)
−x−3=0 or x−4=0(Set factors equal to 0)
x=−3 or x=4
x=−3(Doesn't work in original equation)
x=√x+12
