Looking at x^2 - x - 30, we see that 5*6=30, so we can immediately conclude that <span>x^2 - x - 30 = (x+5)(x-6).  check this by multiplication.

</span><span>2m^2 - 2m - 60 can be reduced to 2(m^2 - m - 30), which in turn can be factored as    2(m+5)(m-6).  The trick here is to notice how easily "2" can be factored out of the given equation.

C=15.7 ft The formula for the circumference of a circle is with the given circumference use 3.14 for π and round to the nearest
Scorpion4ik [409]
<h3>Radius of circle is 2.5 feet</h3><h3>Diameter of circle is 5 feet</h3>

<em><u>Solution:</u></em>

Given that,

Circumference of circle = 15.7 feet

<em><u>The formula for the circumference of a circle is:</u></em>

C = 2 \times \pi \times r

Where, "r" is the radius of circle

Given that,

C = 15.7 feet

Therefore,

15.7 = 2 \times 3.14 \times r\\\\6.28r = 15.7\\\\r = \frac{15.7}{6.28}\\\\r = 2.5

Thus radius of circle is 2.5 feet

Also,

Diameter = 2( radius )

Diameter = 2 (2.5) = 5

Thus diameter of circle is 5 feet
