One edge of a cube measures 5.4 meters. What is the volume of the cube?

matrenka [14]

157.464m^3

This is because using the formula, a^3, you get 5.4^3 which equals 157.464.

Drag each part of the equation to categories it as a term or a coefficient in the expression. Parts that are neither a term nor

faust18 [17]

Answer:

In the given expression:

Term = $x , x$

Coefficient= $-2, (\frac{3}{4})$

Neither one = 5

Step-by-step explanation:

Here, the given expression is : $-2x+\frac{3}{4} x +5$

Now, in the polynomial of the form $ax^{2} + bx + c$

All the x terms involving any powers of x are 'TERM'

Like $x^{2} , x$

All the co efficient of the x in the polynomial are called 'Co -efficient.

Here, a , b are co efficient.

The terms in the polynomial which are neither coefficient nor terms are called 'Constants' . Here, c is constant.

Now, in the given expression:

Term = $x , x$

Coefficient= $-2, (\frac{3}{4})$

Neither one = 5

Which trinomial is a perfect square trinomial? a2 – 18a + 36 a2 – 16a + 64 a2 – 8a + 64 a2 – 6a + 36

Komok [63]

Answer:

$a^2-16a+64$

Step-by-step explanation:

we have the options

$a^2-18a+36\\a^2-16a+64\\a^2-8a+64\\a^2-6a+36$

the one that is a perfect equare tinomial is:

$a^2-16a+64$

because we can rewrite this as follows:

$(a-8)^2$ this is because we know that

$x^2-2xy+y^2=(x-y)^2$

thus

$a^2-16a+64=(x-8)^2$

and the other options cannot be represented as a perfect square trinomial, so the correct answer is:

$a^2-16a+64$
