Answer:
-2 +/- [(sqrt 88)/ 4]
or
0.35, -4.35 to the nearest hundredth.
Step-by-step explanation:
2x^2 + 8x - 3 = 0
Using the quadratic formula:
x = [ -8 +/- sqrt (8^2 - 4*2*-3) ] / 4
= -2 +/- (sqrt 88)/ 4
First your going to use commutative property to reorder the terms , so it would be
5x^4-x-35x^3+7 , then your going to factor out x & -7 from the equation once you factor that out you should have x(5x^3-1)-7(5x^3-1) after you got that your going to factor out 5x^3-2 and get the answer (x-7)(5x^3-1) which is your final answer.

Answer:
5, 10, 15
Step-by-step explanation:
the increase in the sequence is 5 so since it starts from 0 which you can find out because 25 is the 5th sequence and that means that +2*5 =25 . x=0
0+ 5 = sequence 1
0+ 5+5 = seq 2
0+5+5+5= seq 3
Answer:
Rounding up to the nearest hundredth, 907.49
Step-by-step explanation:
10% of 824.99 is 82.499 so all you have to do is 824.99 + 82.499 which will get you 907.48900 and rounding to the nearest hundreth will get you 907.49
