Answer:
-3, 5/2
Step-by-step explanation:
What are the roots of the function y = 4x2 + 2x – 30?
To find the roots of the function, set y = 0. The equation is 0 = 4x2 + 2x – 30.
Factor out the GCF of : 2, so the equation becomes 0 = 2(2x2+x-15)
Next, factor the trinomial completely. The equation becomes: 0=2(x+3)(2x-5)
Use the zero product property and set each factor equal to zero and solve.
x+3=0 2x-5 = 0
x = -3, 5/2
The roots of the function are -3, 5/2.
Hope this helped!
The answer would be 69 km.
Answer:
-84 would be next in the sequence.
Step-by-step explanation:
The formula is x - 17.
-16 - 17 = -33
-33 - 17 = -50
-50 - 17 = -67
-67 - 17 = -84
-84 - 17 = -101 and so on...
This is geometry and you have to add the numbers from adding multiplying iron subtracting or dividing
