Factor 5n^2 - 4n - 12 by grouping. Please show the steps.

Answers

Answer 1
the answer is (5n+6)(n-2)
Answer 2

Answer:

(n - 2)(5n + 6)

Step-by-step explanation:

Given

5n² - 4n - 12

Consider the factors of the product of the n² term and the constant term which sum to give the coefficient of the n- term

product = 5 × - 12 = - 60 and sum = - 4

The factors are - 10 and + 6

Use these factors to split the n- term

5n² - 10n + 6n - 12 ( factor the first/second and third/fourth terms )

= 5n(n - 2) + 6(n - 2) ← factor out (n - 2) from each term

= (n - 2)(5n + 6) ← in factored form

Carpect costs $16 a square foot. A rectangular floor is 16 feet long by 14 feet wide. How much would it cost to carpet the floor?

Answers

Answer:

$3584

Step-by-step explanation:

- because its a rectangle, the area of the floor is length*width, so 16*14 = 224 square feet

- one square foot is $16, so 224 sqaure feet are 224*16

= 3584

Answer:

$3584

Step-by-step explanation:

To find square feet, multiply the length measurement in feet by the width measurement in feet.

16 x 14 = 224

Now, find how much it costs, there is 224 square feet in total so since it's 16 dollar for every square feet.

224 x 16 = 3584

magine you have two friends, Jose and Jessie. Jose is a gifted athlete, but Jessie lives a sedentary lifestyle. Jose and Jessie both ask you to develop an action plan to improve their flexibility. How would your advice differ for Jose and Jessie? Consider specific exercises, frequency of exercise, level of conditioning, levels of flexibility, goal setting, and other important factors in your response.

Answers

Advice for Jose is to start to work-on a more advance level of flexibility such as Knee to chest, side lungs, seat side straddle and more. Advice for Jessie would be to start with the safety doing stretches, perform simple warmups and experiment on doing the spits.

Answer:

First of all, Jose and Jessie have a big difference when it comes to physical health and condition. Jessie is not able to perform the same exercises as Jose, neither the same intensity, and they cannot have the same goal.

So, for Jessie improve her flexibility we have to consider low intensity exercises, specifically, aerobic exercises, like walking, dancing, jogging at a low pace, pilates and yoga. Jessie, as a sedentary person most consider to do those aerobic activities three times per week, at least 30 minutes to ensure that she is demanding enough effort from her body, but all at low intensity.

Which statement correctly describes the relationship between △JKL and △J′K′L′?

△JKL is congruent to △J′K′L′ because you can map △JKL to △J′K′L′ using a reflection across the x-axis, which is a rigid motion.
△JKL is not congruent to △J′K′L′ because there is no sequence of rigid motions that maps △JKL to △J′K′L′.
△JKL is congruent to △J′K′L′ because you can map △JKL to △J′K′L′ using a translation 5 units up, which is a rigid motion.

They were obviously going further so they went more feet, So C is ruled out because it shows them not moving, plus James didn't get a 15 foot head start which is what the C graph shows. Finally it's not B because if you look at the key at the bottom of every graph, it says that Malcolm is the dotted line, and B shows James getting a 20 foot head start, not Malcolm.

Jayvyn Green Each school year, the seventh graders who study Life Science participate in a special field trip to the city zoo. In 2010, the school paid $1,260 for 84 students to enter the zoo. In 2011, the school paid $1,050 for 70 students to enter the zoo. In 2012, the school paid $1,395 for 93 students to enter the zoo. How many students would enter the zoo if the school paid $1,425?*​

Answers

Answer:

95 students

Step-by-step explanation:
