Answer:

Step-by-step explanation:

Hello,

Let 's notice that

$x^2-25=x^2-5^2=(x-5)(x+5) \ \ and \\\\x^2-3x-10=(x-5)(x+2) \ \text{as sum of the zeroes is 3 and the product is -10}$

So the least common denominator is

$(x-5)(x+5)(x+2)$

The Solution:

GIven:

$A=\pi r^2$

Required:

$Find\text{ }r\text{ when }A=81\pi in^2$

Substitute:

$\begin{gathered} \pi r^2=81\pi \\ \\ r^2=\frac{81\pi}{\pi}=81 \end{gathered}$

Take the square root of both sides:

$\begin{gathered} r=\sqrt{81}=\pm9 \\ \\ r=9in\text{ \lparen discard r=-9 since }r>0) \end{gathered}$

-2k = k - 7 - 8 whats the answer

emmasim [6.3K]

Answer:

−2k=k−7−8

−2k=k+−7+−8

−2k=(k)+(−7+−8)(Combine Like Terms)

−2k=k+−15

−2k=k−15

Step 2: Subtract k from both sides.

−2k−k=k−15−k

−3k=−15

Step 3: Divide both sides by -3.
