Answer:

the Anser is B and E

Step-by-step explanation:

In equation, (-d + e)( 4e + d) will be (-4ed - d^2 + 4e^2 +ed ) to simplify we combine the terms with the same variables such as d^2, e^2 and ed. The equation becomes, 4e^2 - 3ed - d^2 . The product has 3 terms with a degree of 2. The statements that are true are B and E.

Answer:

\frac{2}{5}.

Step-by-step explanation:

Let the unknown fraction be \frac{x}{y}  ,

where, x and y both are prime numbers less than 20.

Now, it is given that adding 1 to both numerator and denominator will make the fraction \frac{1}{2}.

Thus,

\frac{x+1}{y+1} =  \frac{1}{2}

2(x + 1) = y + 1

2x + 2 = y + 1

2x + 1 = y.

Clearly if x will be any odd number , two times x will be odd and adding 1 to it will result in even number and y should be even number , which is not possible as only even prime is 2.

Thus , x should be the even prime which is 2.

And y will be 5.

Thus the required fraction is \frac{2}{5}.

Divide a fraction by 1/2 the result was a mixed number was the original fraction less than or greater than 1/2
aliina [53]
Your original fraction was probably greater than 1/2 because if it was less than you wouldn't be able to divide it.
