Answer:
5/8x+1/2x-4=5
or, 5(2x-4)+8x= 5
or, 10x- 20+8x=5
or, 10x-8x= 20+5
or, 2x= 25
or,x= 25/2
:.x= 25/2
Step-by-step explanation:
first we have to make denominator then we can criss cross multiply. we can make in same point .if there is plus we can subtract and if there is front minus if we take it back it must be plus. then we can put same point then we can divide
Short Answer B
Argument
A
A will give you x = +/- 5i
x^2 + 25 = 0
x^2 = - 25 Take the square root.
sqrt(x^2) = +/- sqrt(-25)
x = +/- (5)i which is a complex number.
B
Is the answer
x^2 = 25
sqrt(x)^2 = sqrt(25)
x = +/- 5
C
Can't be factored just by looking at it. You can show that C is not true just by putting 5 into the equation
f(x) = x^2 + 10x - 25
f(5) = 25 + 10*5 - 25
f(5) = 50
C is not true.
D
D can be eliminated as C was
f(x) = x^2 - 5x - 25
f(5) = -25 ( l'll let you show this is not true). 5 is not a solution because it does not make f(x) = 0
