Hey there! :)
Answer:
x = 5/2 and 3.
Step-by-step explanation:
Factor the equation. Find numbers that will sum up to -11 involving the coefficient of 2, and that multiply into 15.
2x² - 11x + 15 = 0
(2x - 5)(x - 3) = 0
Use the Zero Product Property to solve for the roots of this equation:
2x - 5 = 0
2x = 5
x = 5/2
----------
x - 3 = 0
x = 3.
Therefore, the two values of x that are roots of this equation are:
x = 5/2 and 3.
Answer:
1/2
Step-by-step explanation:
Answer:
3:1
Step-by-step explanation:
area is 2D while the perimeter is a length which is 1D. you can also about this in how the area is units squared while the perimeter is just units. so we need the square roote of 9 and 1, sqrt(9) = 3, sqrt(1) = 1. so the ratio of the perimeter is 3:1
Answer:
a) 0
b) 1
c) 0
Step-by-step explanation:
These are common values from the unit circle but you could also just check with your calculator. Just be sure to set it to degree mode and not radian mode.
