Answer:
(x - 5)² = 1
Step-by-step explanation:
x² - 10x + 24 = 0
look for a number that can be added to give -10 and be multiplied to give 24 which is -6 and -4,
i.e -6 + (-4) = - 6 - 4 = -10
(-6) × (-4) = 24
x² - 6x - 4x + 24 = 0
factorize
x(x - 6) -4(x - 6) =0
(x - 4)(x - 6) = 0
(x - 4) = 0
x = 4
x
(x - 6) = 0
x = 6
(x - 5)² = 1
take root of both sides
√(x - 5) = √1
x - 5 = 1
x = 1 + 5 = 6
1. Living Things are Composed of Cells:
Single-cell organisms have everything they need to be "self-sufficient". In multicellular organisms, specialization increases until some cells do only certain things.
2. Different Levels of Organization:
Living things must be able to organize simple substances into complex ones.
Living things organize cells at several levels:
Tissue - a group of cells that perform a common function.
Organ - a group of tissues that perform a common function.
Organ system - a group of organs that perform a common function.
Organism - any complete living thing
3. Living Things Use Energy:
Living things take in energy and use it, for maintenance and growth.
4. Living Things Respond To Their Environment:
Living things will make changes in response to a stimulus in their environment. A behavior is a complex set of responses.
5. Living Things Grow:
Cell division - the orderly formation of new cells.
Cell enlargement - the increase in size of a cell. Cells grow to a certain size and then divide.
An organism gets larger as the number of its cells increases.
6. Living Things Reproduce:
Reproduction is not essential for the survival of individual organisms, but must occur for a species to survive.
All living things reproduce in one of the following ways:
Asexual reproduction - Producing offspring without the use of gametes.
Sexual reproduction - Producing offspring by the joining of sex cells.
7. Living Things Adapt To Their Environment:
Adaptations are traits giving an organism an advantage in a certain environment.
Variation of individuals is important for a healthy species.
