Answer:
25
Step-by-step explanation:
Theres a ratio of 1:4
Where Jamie has driven 4 times as much as Rhonda
meaning that you can plug in values, 1:4=125
the 4 represents Jamie since she drove farther than rhonda
Rhonda drove 25 miles, and Jamie drove 100 miles
25(4)+25=124
Answer:
The discrimant of this equation is 144.
Step-by-step explanation:
First you have to move all the variables to one side to make the equation/expression into 0 by substracting 8x² to both sides :
9x² + 14x + 13 = 8x²
9x² + 14x + 13 - 8x² = 8x² - 8x²
x² + 14x + 13 = 0
It is given that the formula of discriminant is, D = b² - 4ac where a&b&c represent the number of the equation, ax²+bx+c = 0 :
x² + 14x + 13 = 0
D = b² - 4ac
= 14² - 4(1)(13)
= 196 - 52
= 144
