Answer:

Well factorizing 16x^2-49

You can use the difference of squares

Which is when theirs 2 perfect sqaures and it’s a subtraction problem.

So 16x^2 - 49

the formula is

a^2-b^2= (a+b) (a-b)

16x^2 - 7^2 = (a+b) (a-b)

SO plug it in

(4x+7) (4x-7)

Thats simplified to the max

So your answer would be (c)

16x² - 49

= (4x)² - 7²

Identity =》 a² - b² = (a + b) (a - b)

(4x)² - 7²

= (4x + 7) (4x - 7) [3rd option]

A notary receives $ 3500 for elaborating a title property and $2000 for the constitutive act of an enterprise. In a month did a
Andrew [12]

Answer:

6 titles and 16 acts were elaborated

Step-by-step explanation:

Let the number of titles be t and the number of acts be a

Since the total is 22 operations:

a + t = 22 •••••••(i)

Total amount from titles = 3500 * t = 3500t

Total amount from acts = 2000 * a = 2000a

2000a + 3500t = 53,000 ••••••(ii)

From i, a = 22-t

Insert this in ii

2000(22-t) + 3500t = 53,000

44,000 - 2000t + 3500t = 53,000

1,500t = 53000-44000

1500t = 9000

t = 9000/1500

t = 6

But a = 22 -

= 22-6 = 16

Which measurement that does not belong 3500 km, 3.5 m, 350cm, 3500mm
scoundrel [369]
Hello! 3.5m is equivalent to 350cm, which is also equivalent to 3,500mm. 100cm = 1 meter and 10mm = 1cm. 350/100 is 3.5. 3,500/10 is 350. 3,500 km does not belong, because that measurement would be way too big. The answer is 3,500km
