Answer:

  4 1/8 inches

Step-by-step explanation:

You apparently want to find the sum (in inches) ...

  5.5 + (1 3/4) - (3 1/8)

This can be done a number of ways. One is to use an appropriate calculator.

__

Another way to do this is to add the integer parts and fraction parts separately:

  = (5 +1 -3) +(1/2 +3/4 -1/8)

  = 3 + (4/8 +6/8 -1/8) = 3 + (4+6-1)/8 = 3 9/8

  = 4 1/8

__

Another way is to convert all the numbers to decimal, then add.

  = 5.500 +1.750 -3.125

  = 7.250 -3.125

  = 4.125 = 4 1/8

__

There were 4 1/8 inches of snow remaining Tuesday evening.

What are the dimensions of a rectangular box with a volume of 50b 3 + 75b2 - 2b - 3?
Inessa [10]

Answer:

\large\boxed{(2b+3)\times(5b-1)\times(5b+1)}

Step-by-step explanation:

The formula of a volume of a rectangular box:

V=lwh

<em>l</em><em> - lenght</em>

<em>w</em><em> - width</em>

<em>h</em><em> - height</em>

V=50b^3+75b^2-2b-3=25b^2(2b+3)-1(2b+3)\\\\=(2b+3)(25b^2-1)=(2b+3)(5^2b^2-1^2)\\\\=(2b+3)\bigg((5b)^2-1^2\bigg)\qquad\text{use}\ a^2-b^2=(a-b)(a+b)\\\\=(2b+3)(5b-1)(5b+1)

Therefore the dinemsions of thisp prism are:

(2b+3)\times(5b-1)\times(5b+1)

Which of the following options correctly represents the complete factored form of the polynomial F(x)=x^4-3x^2-4?
Bumek [7]

Answer:

D

Step-by-step explanation:

Let's substitute a for x²:

x^4 - 3x² - 4

a² - 3a - 4

Now, this looks like something that is much more factorisable:

a² - 3a - 4 = (a - 4)(a + 1)

Plug x² back in for a:

(a - 4)(a + 1)

(x² - 4)(x² + 1)

The first one is a difference of squares, which can be factored into:

x² - 4 = (x + 2)(x - 2)

The second one can also be treated as a difference of squares:

x² + 1 = x² - (-1) = (x + √-1)(x - √-1) = (x + i)(x - i)

The answer is (x + 2)(x - 2)(x + i)(x - i), or D.

Help me with a question?
kherson [118]

Answer:

B

Step-by-step explanation:

y = mx + b

The slope is m.

If it was anything other than 0, the line would have an x in it. The line does not have an x associated with it.

The equation of the line is y = 1

The slope must be 0.
