about 0.4 of a biology class will be going on a field trip . write the decimal as a fraction in simplest form .

1 answer:

3 0

0.4 is $\frac{4}{10}$ and that simplified is $\frac{2}{5}$ because you take the GCF or Greatest Common Factor, which is two, and divide both parts of the fraction taking $\frac{4}{10}$ and turning it into $\frac{2}{5}$

2.) What value for c will make the expression a perfect square trinomial?

andre [41]

Answer : $\frac{49}{4}$

Given expression is $x^2 - 7x + c$

To make perfect square trinominal we use completing the square method

In completing the square method we add and subtract the half of square of coefficient of middle term

Here coefficient of middle term is -7

Half of -7 is $\frac{-7}{2}$

Square of $\frac{-7}{2}$ is $(\frac{-7}{2})^2$ = $\frac{49}{4}$

So the expression becomes $x^2 - 7x + [tex] \frac{49}{4}$ that gives perfect square trinomial

Hence , the value of 'c' is $\frac{49}{4}$
