Simplify the following expresion. Classify the resulting polynomial 4x(x+1)-(3x-8)(x+4) A) quadratic monomial B) quadratic trino

lana66690 [7]

Answer:

Quadratic binomial

Step-by-step explanation:

4x(x+1) - (3x-8)(x+4)

Open parenthesis

(4x^2+4x) - (3x^2+12x-8x-32)

(4x^2+4x - 3x^2-12x+8x+32)

Collect like terms

4x^2-3x^2+4x+8x-12x+32

=x^2+32

Y = f(x) = 16x Find f(x) when x = 1/2

Alina [70]

Answer:

The answer depends on what the problem really is.

f(1/2) = 8

f(1/2) = 4

See below.

Step-by-step explanation:

This is the problem as it was posted:

y = f(x) = 16x

Let x = 1/2

y = f(1/2) = 16(1/2) = 8

Perhaps the problem is this:

$y = f(x) = 16^x$

If x is an exponent of 16 and not a factor, then the answer is:

$y = f(\frac{1}{2}) = 16^\frac{1}{2} = \sqrt{16} = 4$

In this fulcrum, the weights are perfectly balanced. How far must the fulcrum be located from the 40 lb. weight if the bar is 9

creativ13 [48]

So...we can write eqn as

40x = 50(x-1)
so. -10x=-50
so. x=5

therefore .... the distance of 40 lb will be 5 ft ...answer !!!

Simplify negative 3 over 2 / 9 over 6

Temka [501]

$\mathrm{Simplify} -\frac{3}2\div\frac{9}6.$

Dividing by a fraction is the same as multiplying by its reciprocal. (flipped version)

$-\frac{3}2\div\frac{9}6=-\frac{3}2\times\frac{6}{9}$

6 and 9 are both divisible by 3, so we can simplify 6/9 = 2/3.

$-\frac{3}2\times\frac{2}3$

We can multiply across right now, but we might as well cross cancel.
Look at the numbers diagonal from one another...-3 and 3 are both divisible by 3, so we can change them to -1 and 1...2 and 2 are both divisible by 2, so we can change them to 1 and 1...

$-\frac{1}1\times\frac{1}1$

Any fraction over 1 can just be expressed as a whole number.

$-1\times1$

Our final answer... $-\frac{3}2\div\frac{9}6=\boxed{-1}$

If you were to multiply across, (maybe you don't like cross cancelling, idk?) you'd get the same answer, of course.

$-\frac{3}2\times\frac{2}3=-\frac{6}6=\boxed{-1}$
