Simplify completely quantity 12 x plus 36 over quantity x squared minus 4 x minus 21 and find the restrictions on the variable..
Softa [21]
To simplify the expression stated, it is better to write it in the numerical form. The statement is:

<span>quantity 12 x plus 36 over quantity x squared minus 4 x minus 21

The numerical form is:

12x+36 / (x</span>²-4x-21)

Simplifying,
12x+36 / (x<span>²-4x-21)
</span>12 (x+3) / (x+3)(x-7)

We can cancel the x+3 term, leaving only:
12/(x-<span>7)</span>

Convert the number to standard form.<br><br> 8.71 xx10^(12)
ExtremeBDS [4]

8.71 xx10^(12)

The exponent is a positive number. This means the decimal point moves to the right by  the number of the exponent.

There are two digits to the right of the decimal point, so to move the decimal 12 places, you would need to add 10 zeros.

8.71 x 10^12 becomes 8,710,000,000,000.

A 150-N bird feeder is supported by three cables. Find the tension in each cable.
Irina-Kira [14]
X axis : -t1 cos 60 + t2 cos 60 = 0
 
            t2 cos 60   = t1 cos 60    ; t2   = t1

Y axis : t1 sin 60  + t2 sin 60 - 150 = 0

since t2 = t1

2t1 sin 60 =  150

t1 ( sqrt(3)/2)  = 150/2

t1   = 50 [sqrt(3)]

t2 = 50 [sqrt(3)]

t3 = 150 N

hope this helps

X^3+x²-36 Find all real zeros.
Harman [31]

Answer: x=3

Step-by-step explanation:

To find the zeros, you want to first factor the expression.

x³+x²-36

(x-3)(x²+4x+12)

Now that we have found the factors, we set each to 0.

x-3=0

x=3

Since x²+4x+12 cannot be factored, we can forget about this part.

Therefore, the zeros are x=3. You can check this by plugging the expression into a graphing calculator to see the zeros.
