Find the zeros of x^2+4x=-10 using the quadratic formula
ipn [44]
X^2+4+10=0
x=(-4(+/-)root16-40)/2, so we now know that the zeros are imaginary, because you can't square root a negative number and 16-40 is -24
so the two roots are…
-2+iroot6 and -2-iroot6

In a scale drawing, a building has a length of 15 cm. The actual length of the building is 37.5 feet. Whats the scale of the dra
Feliz [49]

Answer:

\frac{15}{37.5}\ \frac{cm}{ft}

or

1.31:100

Step-by-step explanation:

we know that

The scale of the drawing is equal to divide the length of a building in the scale drawing by the actual length of a building

so

\frac{15}{37.5}\ \frac{cm}{ft}

That means

15 cm in the drawing represent 37.5 ft in the actual

Remember that

1\ ft=30.48\ cm

Convert 15 cm to ft

divide by 30.48

15\ cm=15/30.48\ ft

substitute

\frac{15}{37.5}\ \frac{cm}{ft}=\frac{(15/30.48)}{37.5}=\frac{0.0131}{1}

or

1.31:100

That means

1.31 units in the drawing represent 100 units in the actual

elena55 [62]

Answer:$32


Step-by-step explanation: So if the double pack of CD's is 20 dollars and that $4 less than 3/4 of the triple pack, then $20 + $4 = $24, then to find how much 1/4 of the cost is we divide 24 by 3, getting $8. Finally we multiple $8 by 4 to get $32, so the cost for a triple pack is $32.
