Unit Test

Fantom [35]

Answer:

x = -6, or x = 7 is the ONLY correct solution of the given equation $x^{2} + x - 30 = 12.$

Step-by-step explanation:

Here, the given expression is $x^{2} + x - 30 = 12.$

or the standard form of the above expression is $x^{2} + x - 30 - 12 = 0$

or, $x^{2} + x - 42 = 0$

Now, if the equation is of the form $ax^{2} + bx + c = 0$

Then, b = SUM OF THE ROOTS

and c = PRODUCT OF THE ROOTS

Similarly, in the above expression:

b = 1 = Sum of roots

and c = -42 = Product of the roots.

Here, for x = -6, or x = 7:

Sum of Roots = -6 + 7 = 1

Product of roots = (-6)(7) = -42

Hence, x = -6, or x = 7 is the ONLY correct solution of the given equation.

Se tienen dos libros: uno de 240 página y otro de 160 páginas. Si los 2 libros están formados por cuadernillos con el mismo núme

mafiozo [28]

Answer:

Book of 240 pages has 12 booklets in total

Book of 160 pages has 8 booklets in total.

Total booklets both the books have in total = 20

Step-by-step explanation:

Given - There are two books: one of 240 pages and the other of 160 pages. If the 2 books are made up of booklets with the same number of pages (between 16 and 28),

To find - How many booklets do the two books have in total?

Proof -

Given that, Number of pages of a booklet is between 16 and 28.

So, The number that lies between 16 and 28 will have to divide the number of pages of both the books.

(Because given that both the books are made up of booklet with the same number of pages)

By inspection, we get

The number of pages of a booklet = 20

because

240/20 = 12 and 160/20 = 8

∴ we get

1 booklet = 20 pages

i.e.

20 pages = 1 booklet

⇒1 page = $\frac{1}{20}booklet$

⇒240 pages = $\frac{240}{20}booklet$ = 12 booklet

So, we get

The book of 240 pages has 12 booklets in it.

Now,

1 page = $\frac{1}{20}booklet$

⇒160 pages = $\frac{160}{20}booklet$ = 8 booklet

So, we get

The book of 160 pages has 8 booklets in it.

∴ we get

Book of 240 pages has 12 booklets in total

Book of 160 pages has 8 booklets in total.

So, Total booklets both the books have = 12 + 8 = 20
