3 times a number is 54 less than the square of that number

Natasha2012 [34]

Answer:

-6

Step-by-step explanation:

3n = n² - 54

n² - 3n - 54 = 0

n² - 9n + 6n - 54 = 0

n(n - 9) + 6(n - 9) = 0

(n - 9)(n + 6) = 0

n = 9 , -6

sweet-ann [11.9K]

Given;

ABCDE is similar to VWXYZ

so, the corresponding segments are proportional

We need to find the length of XY

XY is corresponding to CD

CD = 1.2 cm

Finding another two corresponding sides

DE = 3.2 cm , YZ = 4 cm

so,

$\begin{gathered} \frac{XY}{CD}=\frac{YZ}{DE} \\ \\ \frac{XY}{1.2}=\frac{4}{3.2} \\ \\ XY=\frac{4}{3.2}\cdot1.2=1.5\operatorname{cm} \end{gathered}$

So, the length of XY = 1.5 cm

X is inversely proportional to y, and x = 18 when y = 4. Write an equation relating the two

Alenkasestr [34]

Answer:

$xy=72$

Step-by-step explanation:

If x is inversely porportionaly to y, then for some constant k,

$x = \frac{k}{y}\\xy=k$

Since y is 4 when x = 18, k is equal to 4*18=72, so the equation is:

$xy=72$
