$x ^(2) - 8x = 3$ solve by factoring please. I really need help I have no clue how to solve by factoring like I forgot the steps so can u work the steps out also please

Answers

Answer 1

Answer:

Answer:

$x = 4 + √(19)$

Step-by-step explanation:

To solve by factoring, complete the square by dividing 8 from 8x in 2. Then square the result 4 to get 16. Add 16 to both sides.

$x^2 -8x = 3\n\nx^2 - 8x + 16 = 3 + 16\n\n(x-4)^2 = 19$

The equation is now factored. To solve, take the square root of both sides and solve for x.

$√((x-4)^2) = √(19)\n\nx-4 = √(19) \n\nx = 4 + √(19)$

low tide is 1 foot below the average water level. High tide is 5 feet higher than low tide. Write an integer that represents the average water level relative to high tide.

Answers

The integer that represents the average water level relative to high tide exist H - 2.5.

What is meant by an integer?

A number that contains both positive and negative integers, including zero, is called an integer. There are no fractional or decimal parts in it.

Zero, a positive natural number, or a negative integer denoted by a minus sign are all examples of integers. The inverse additives of the equivalent positive numbers are the negative numbers.

Given: Low tide is 1 ft below avg. water level.

High tide is 5 ft higher then low tide.

If A be the average and L exists low tide level then high tide H = L+5.

A = ½(L + H)

L = A - 1

H = L + 5, or L = H - 5.

The integer representing average water level relative to high tide. I guess this indicates to express A in terms of H.

A = ½(L + H) = ½(H-5 + H)

A = H - 2.5

Therefore, the integer that represents the average water level relative to high tide exist H - 2.5.

The complete question is:

Low tide is 1 ft below avg. water level. High tide is 5 ft higher than low tide. Write the integer representing avg water to high tide.

Low tide is one foot below the average water level. High tide is 5 feet higher than low tide. Write an integer that represents the average water level relative to the high tide.
