Answer:

\frac{-89}{40}

As a Proper Fraction: -2\frac{9}{40}

Step-by-step explanation:

So i assume the fraction sits like this:

\frac{-5}{8} + \frac{-8}{5}

This essentially becomes:

\frac{-5}{8}  -  \frac{8}{5}

Now multiply the denominators for a LCM (Lowest common denominator)

8*5 = 40

And now multiply the top parts with the respective denominator (-5 * 5) and (8 * 8)

So Now you get

\frac{-25}{40} -  \frac{64}{40}

and now that u have same denominators, just subtract -25 - 64  and get -89

Final Simplified answer: \frac{-89}{40}

As a Proper Fraction: -2\frac{9}{40}

What is the volume of the composite figure?<br> 12in<br> 4 in<br> 3 in.<br> 7 in.
Minchanka [31]

Answer:

Step-by-step explanation:

V_p = b \cdot h \cdot w, where b, h, w are base, height and width respectively.

V_{sp} = \frac{1}{3} \cdot {A_b} \cdot h, where h is the height, and A_b is the area of the base.

First let's calculate the volume of the paralelipiped by the first formula.

V_p = 7 \cdot 4 \cdot 3 = 84 in^2

Then let's find out the height of the pyramid, which is 12 - 4 = 8 in.(See drawing)

Then the area of the base of the square pyramid is simply.

A_r = 3 \cdot 7 = 21 in^2

Now we can find the volume of the pyramid.

V_{sp} = \frac{1}{3} \cdot 21 \cdot 8 = 56 in^3

To find the total volume, let's add both volumes.

V_T = 84 + 56 = 140 in^3

3. Complete the square for 3x2 - 6x = 21.<br> Help
PSYCHO15rus [73]

Answer:

x=1+2√2 or x=1−2√2

Step-by-step explanation:

Let's solve your equation step-by-step.

3x2−6x=21

Step 1: Since the coefficient of 3x^2 is 3, divide both sides by 3.

3x2−6x

3

=

21

3

x2−2x=7

Step 2: The coefficient of -2x is -2. Let b=-2.  

Then we need to add (b/2)^2=1 to both sides to complete the square.

Add 1 to both sides.

x2−2x+1=7+1

x2−2x+1=8

Step 3: Factor left side.

(x−1)2=8

Step 4: Take square root.

x−1=±√8

Step 5: Add 1 to both sides.

x−1+1=1±√8

x=1±√8

x=1+2√2 or x=1−2√2

F(x)=x+2,translation 2 units right
weeeeeb [17]

Answer:

when you translate you move the "x" term.  

so moving to the right is x-2 (sign opposite of direction)

g(x) = (x-2) + 2
