Answer:
x= 36
(it is positive since 78 is larger than 42, everything else is correct)
Step-by-step explanation:
It would be D. 5/20 because the other 2 you would add then subtract and then you would just put the answer yo get from subtracting it over 20.
Answer:
d(1) = -3 and d(2)= -28
Step-by-step explanation:
Given that the distance d, in centimeters, that a diving board bends below its resting position when you stand at its end is dependent on your distance x, in meters, from the stabilized point
For finding out the distances for x=1 and x=2
let us substitute 1 and 2 for x
d(1) = -3 and d(2)= -28
Rewriting the formula in standard form would be x^2-8x+14=0
Answer:
x² - 4x + 3
Step-by-step explanation:
When multiplying binomials (two terms in an expression), use FOIL. It stands for the first, outside, inside, and last terms in each bracket.
(x−3)(x−1) Expand with FOIL
= x² - x - 3x + 3 Collect like terms
= x² - 4x + 3
