2. 2a^5 + 5b

Step-by-step explanation:

1. Simplify 4(x^2 -1) to 4x^2 -4

then add that to 6x^2

2. 4a^5 - 2a^5 = 2a^5 and

Answer:

Step-by-step explanation:

6x² + 4(x² - 1) = 6x² + 4*x² - 4*1

           = 6x² + 4x² - 4    

            = 10x² - 4

4a⁵ - 2a⁵ + 4b +b = 2a⁵ + 5b

You have to add/ subtract the like terms

4a⁵ and 2a⁵ are like terms

4b and b are like terms

Factor 36x^2 + 11x-12 please hurry​
xz_007 [3.2K]

Answer:

The answer is

<h2>(9x - 4)(4x + 3)</h2>

Step-by-step explanation:

36x² + 11x - 12

To factor the expression rewrite 11x as a difference

That's

36x² + 27x - 16x - 12

<u>Factor out 9x from the expression</u>

9x( 4x + 3) - 16x - 12

<u>Factor out - 4 from the expression</u>

9x( 4x + 3) - 4( 4x + 3)

Factor out 4x + 3 from the expression

We have the final answer as

<h3>(9x - 4)(4x + 3)</h3>

Hope this helps you

Joe hosted a praty 582 people came he charged 15 dollars for balcony seats and 10 dollars for ground seats how many people bout
hoa [83]

Answer:

Ground seats = 450 people

Balcony seats= 132 people

Step-by-step explanation:

Hi, to answer this question we have to write a system of equations:

The money raised (6480) must be equal to the product of the charge per balcony seats (15) and the number of balcony seats sold (b) ;plus the product of the charge per ground seats (10) and the number of ground seats sold (g)

15 b +10 g =6480

The total number of people (582) must be equal to the sum of balcony seats sold (b) and ground seats sold (g).

b+g = 582

Multiplying the second equation by 10, and subtracting it to the first equation:

15 b +10 g =6480

-

10b+10g = 5820

__________

5b =660

Solving for b

b = 660/5 = 132

Substituting b=132 in the second equation:

132+g = 582

g= 582-132

g= 450

In printing an article of 48,000 words, a printer decides to use two sizes of type. Using the larger type, a printed page contai
9966 [12]

Answer:

17 pages

Step-by-step explanation:

Let L = number of pages printed Larger type

S = number of pages printed smaller type

 the article is allow 21 full pages in a magazine. -->L + S = 21

1,800L + 2, 400S = 48, 000 (we can divide 100 to make the math easier)

18L + 24S = 480

Solve:

L + S = 21

18L + 24S = 480

we can use elimination by eliminating 18L so we can isolate the value of S  

-18 (L + S = 21)

18L + 24S = 480

-18L - 18S = 378

18L + 24S = 480

6S = 102

S = 17
