SOMEONE PLEASE JUST ANSWER THIS FOR BRAINLIEST!!!Subtract 3a^2 + 5ab - 4b^2 from 8a^2 - 6ab + 4b^2.

The answer should be a polynomial in standard form.

Answers

Answer 1
Answer:

(8a² - 6ab + 4b²) - (3a² + 5ab - 4b²) distribute the negative sign and combine like terms

(8a² - 6ab + 4b²) (-3a² - 5ab + 4b²)

8a² and -3a² equals 5a²

-6ab and -5ab equals -11ab

4b² and 4b² equals 8b²

the answer is 5a² - 11ab + 8b²

Hope this helps!!

Ln(x + 1) − ln(2) = 1

Answers

Answer:

The answer to your question is: x = 4.44

Step-by-step explanation:

Data

                                          ln(x + 1) − ln(2) = 1

                                          In (x + 1)/2 = 1

                                          (x + 1) / 2 = e¹      

                                          x + 1 = 2 (2.7183)

                                          x = 5.44 - 1

                                          x = 4.44        

You have 324 ft^2 of fabric to make a circular play parachute for kids. What is the radius of the largest parachute you can make? Round to the nearest tenth of a foot.

Answers

Area of a circular play parachute:
A = 324 ft²
A =  r² π
r² π = 324
r² = 324 : 3.14
r² = 103.1874
r = √103.1874
r = 10.157987 ≈ 10.2 ft

21/4+55/6+32/3 simplify

Answers

21/4 + 55/6 + 32/3

Rules in adding fraction.
1) Get the Least Common Denominator.
multiple of 4: 4, 8, 12
multiple of 6: 6, 12, 18
multiple of 3: 3, 6, 9, 12    Least Common Denominator is 12.

21/4 * 3/3 = 63/12
55/6 * 2/2 = 110/12
32/3 * 4/4 = 128/12

2) Add the numerators and place the sum above the least common denominator

63/12 + 110/12 + 128/12 = (63+110+128)/12 = 301/12

3) Simplify the fraction

301/12 is an improper fraction. To simplify an improper fraction, a mixed fraction will result.

301/12 = 25 1/12
steps :
421/4 + 55/6 + 32/3 = 63/12 + 110/12 + 128/12 
= (63 + 110 + 128)/12 = 301/12 = 25 1/12


The correct result is 301/12 or 25 1/12.

Hope that helped =D
