Factor 6x? + x – 12 by grouping.<br> C
Semenov [28]

Answer:

6x² + x - 12 =  (2x + 3) (3x - 4)

Step-by-step explanation:

Factor 6x² + x - 12 by grouping

we need to rewrite the middle term as a sum of two terms whose product is (6* −12) = −72 and whose sum is 1

The middle term = x = 9x - 8x

  6x² + x - 12

= 6x² + 9x - 8x - 12       Grouping the first two terms and the last two terms

= (6x² + 9x) + ( - 8x - 12)

From the first two terms take 3x as a common and from the two terms take (-4) as a common

= 3x ( 2x + 3) -4 (2x + 3)

Take (2x + 3) as a common

= <u> (2x + 3) (3x - 4)</u>

Which of the playground’s features are more than 25 feet away from the swings? Choose the THREE correct answers.
crimeas [40]

The playground’s features are more than 25 feet away from the swings are;

<em><u>Sandbox, Water fountain, Jungle gym</u></em>

Looking at the given graph, the distances of the other features from the swing are;

For sandbox; 8 units

For restroom; 4 units

For water fountain; 9 units

For Jungle gym; 7 units

Bench; 5 units

Now we are told that each units on the graph represents 5 ft.

Thus, the respective distances from the swing are;

Sandbox to swing = 8 × 5 = 40 ft

Restroom to swing = 4 × 5 = 20 ft

Water fountain to swing = 9 × 5 = 45 ft

Jungle gym to swing = 7 × 5 = 35 ft

Bench to swing = 5 × 5 = 25 ft

Thus, the playground’s features are more than 25 feet away from the swings are;

Sandbox, Water fountain, Jungle gym

First, move 9x^2 to the right:

7y^2 = 42 - 9x^2

Then, divide 7 on both sides:

y^2 = 6 - 9/7 * x^2
