Step-by-step explanation:
The water level is 8 feet below your dock.
The tide goes out, and the water level lowers
2 foot. A storm surge comes in, and the
water level rises 3 feet. Write an addition
expression to find the new water level.
Answer:
factorisation method
4x² - 3x + 9 = 2x + 1
4x² - 3x-2x +9-1 = 0
4x² - 5x + 8 = 0
sum = -5
product= 4x8
32
factors=(try to look for the numbers when added they give -5 a!d when multiplied they give 32
press the numbers in the position of -5
factorise
each blacket equal it to 0
and solve for the two values of x
-1(x) or -x. In your case, -1(-7).
Which one the highlight one
