in the figures below the cube shaped box is 6 inches wide and the rectangular box is 10 inches long 4 inches wide and 4 inches h

IRINA_888 [86]

<span>The cube’s sides measures 6 inches and the measurement for the rectangular box is that it is 10 inches long, 4 inches thick and 4 inches high. To compute for the volume of a cube you must use the formula of V = a3 and for the rectangular prism is V = l x w x h.</span>
<span>Cube:    V = 6^3
</span> <span>V = 216 inches^3</span>
<span>Rectangular Prism:       V = 10 x 4 x 4</span> <span>
                                 V = 160 inches^3</span>
To identify how much greater the volume the cube from the rectangular box we subtract their volumes.
N = C – R where N stands for the unknown C for the volume of cube and R for the volume of Rectangular Box <span>
N = 216 inches^3 – 160 inches^3
</span> <span>N = 56 inches^3</span> <span>
So the cube is 56 inches3 greater than the rectangular box.</span>

the length of a rectangle is 5 inches longer than twice the width and the area is 12 inches squared. Let l represent the length

svet-max [94.6K]

Answer:

Length = 8 inch , Width = $\frac{3}{2}$ , This equation models the situation

Step-by-step explanation:

Given as ;

The Area of Rectangle is 12 inches²

The Length of Rectangle is 5 inches longer than twice the width

Let The Length = L inches

The Width = W inches

According to question ,

L = 5 + (2 × w )

∵ The Area of Rectangle = Length × width

Or, 12 inches² = [ 5 + (2 × w ) ] × w

Or, 12 inches² = 5 w +2 w²

Or, 2 w² + 5 w - 12 = 0

Or, 2 w² + 8 w -3 w - 12 = 0

Or, 2 w (w +4) - 3 (w + 4) = 0

I.e (w + 4) ( 2 w - 3) = 0

So , w = -4 , and w = $\frac{3}{2}$

∴ Length = 5 + (2 × w ) =

Length = 5 + (2 × $\frac{3}{2}$ )

so , L = 5 + 3 = 8

Hence Length = 8 inch , Width = $\frac{3}{2}$ This equation models the situation Answer

How many zero pairs must be added to the function

MakcuM [25]

1 zero pair of 25 was added to bring given function into vertex form.

<h3>What is a Zero Pair ?</h3>

A zero Pair is the set of two numbers which when added together gives 0.

The function given is

f(x) = x² -10x -4

To convert it into the vertex form

y = a(x-h)² +k

f(x) = x² -10x +25 -25 -4

f(x) = x² -10x +5² -25-4

f(x) = (x-5)² -29

Therefore this is the given function's vertex form and

1 zero pair of 25 was added to bring it into that.

Therefore Option D is the answer.
