Answer 1

$\huge\star{\boxed{\underline{\boxed{\boxed{\pink{ANSWER}}}}}}$

Cells are the basic building blocks of living things. The human body is composed of trillions of cells, all with their own specialised function. Cells are the basic structures of all living organisms. Cells provide structure for the body, take in nutrients from food and carry out important functions.

Answer 2

Answer:

Solution :-

➜ x² - 8x + 7 = 0

➞ x² - (7 + 1)x + 7 = 0

➞ x² - 7x - x + 7 = 0

➞ x(x - 7) - 1(x - 7) = 0

➞ (x - 7) (x - 1) = 0

➞ (x - 7) = 0

➞ x - 7 = 0

➞ x = 7

Either,

➞ (x - 1) = 0

➞ x - 1 = 0

➞ x = 1

∴ The answer of this question is x = 7, 1
