14.4 cm

First, find side lengths,

<span>A = </span><span>12</span>bh
<span>270.633 = </span><span>12</span>b(21.65)
b = 25

<span>Thus, 25 is the side lengths of the equilateral </span>triangle.

<span>To find the </span>radius<span> use,</span>

<span>r = </span><span><span>a3</span>3</span>
<span>r = </span><span><span>253</span>3</span>
<span>r = 14.43</span>

Scrat [10]

Answer: (3x−2)(4x−1)

Step-by-step explanation:

<em>Start factoring with -11x.</em>

12x^(2)-11x+2

12x2+(−8−3)x+2

12x2+(−8x−3x)+2

12x2−8x−3x+2

<em>Factor the highest common denominator of each group.</em>

<em>Group the first two terms and the last two.</em>

(12x2−8x)+(−3x+2)

<em>Factor the highest common denominator (MCD) of each group.</em>

<em>4x(3x−2)−(3x−2)</em>

<em>Factoring the highest common denominator 3x−2.</em>

(3x−2)(4x−1)

leva [86]

Answer:

12

Step-by-step explanation:

3*4 = 12

12/6 = whole number

6/4 is not a whole number

12 is the lowest it could be.

Also those kids have issues.

hjlf

Answer:

12 miles

Step-by-step explanation:

Alyssa takes part in the triathlon. She cycles 4/5 of the route, runs 1/8 of the route, and swims the rest of the way. She swims 0.9 miles. Find the total distance of the triathlon route.

Total distance Alyssa cycled and ran =

\frac{4}{5} + \frac{1}{8}

\frac{32 + 5}{40} = \frac{37}{40}

Distance she swam =  1 - 37/40 = 3/40

3/40 of the distance is 0.9

the total distance = 40/3 x 0.9 = 12 miles
