How do I simplify ((3x^2+12x+12)/(2x^2+x-6))/((4x^2-9)/(3x^3+x^2-10))

Shalnov [3]

$\dfrac{ \frac{3x^2+12x+12}{2x^2+x-6} }{ \frac{4x^2-9 }{3x^3+x^2-10} } =$

$= \dfrac{3(x + 2)^2}{(2x - 3)(x + 2)} \times \dfrac {3x^3+x^2-10} {(2x + 3)(2x - 3)} }$

$= \dfrac{3(x + 2)}{2x - 3} \times \dfrac {3x^3+x^2-10} {(2x + 3)(2x - 3)} }$

$= \dfrac{3(x + 2)(3x^3+x^2-10) }{(2x - 3)^2(2x + 3)}$

450 meals served at 75 campus cafeteria 98 had less than 10 grams of fat but not less than 350 calories;110 had less than 350 ca

igor_vitrenko [27]

Incomplete question. The remaining question read;

What percentage of meals had less than 10 grams of fat? Round your answer to the nearest tenth of a percent.

Answer:

21.7%

Step-by-step explanation:

Remember, we are told that 98 out of the 450 meals served at 75 cafeterias had less than 10 grams of fat.

To calculate the percentage, we divide 98 by 450 and then multiply by 100:

$\frac{98}{450}*100=$ 21.7% approximately to the nearest tenth of a percent.

Find the lengths of the sides of the triangle PQR. Is it a right triangle? Is it an isoseceles triangle?(a)P(3,−2,−3),Q(7,0,1),R

lawyer [7]

Answer:

(a) It is an isosceles triangle with sides of lengths: 6, 2√10, and 6 units.

(b) It is a right-angled triangle with hypotenuse side of 3√5 units, and opposite and adjacent sides of 6 and 3 units

Step-by-step explanation:

(a) P(3,−2,−3), Q(7,0,1), R(1,2,1)

|PQ| = √[(7-3)² + (0+2)² + (1+3)²]

= √(4² + 2² + 4²)

= √36

= 6

|QR| = √[(1-7)² + (2-0)² + (1-1)²]

= √((-6)² + 2² + 0)

= √40

= 2√10

|RP| = √[(3-1)² (-2-2)² (-3-1)²]

= √[(2² + (-4)² + (-4)²]

= √36

= 6

|PQ| = |RP|

So, triangle is isosceles.

(b) P(2,−1,0), Q(4,1,1), R(4,−5,4)

|PQ| = √[(4-2)² + (1+1)² + (1-0)²]

= √(2² + 2² + 1²)

= √9

= 3

|QR| = √[(4-4)² (-5-1)² (4-1)²]

= √[(0 + (-6)² + 3²]

= √45

= 3√5

|RP| = √[(2-4)² + (-1+5)² + (0-4)²]

= √((-2)² + 4² + (-4)²)

= √36

= 6

|PQ|² + |RP|² = |QR|²

So, triangle is right-angled
