Answer:
Step-by-step explanation:
(2x+5)(x+1) = 2x²+2x+5x+5
(2x+5)(x+1) =2x²+7x+5.....standard form
Answer:
4 hours
Step-by-step explanation:
Write an equation:
30x+97=217
Subtract 97 on both sides
30x=120
divide 30 on both sides to isolate the variable
x=4
Your answer is 10+14+18+22+26+30+34+38+42+46+50+54+58+62+66+70+74=714
For the first problem,
The definite integral from 0 to c is
[f(c) - f(0)] / (c - 0)
since the function is continuous in the interval 0 to c.
Since f(a) = f(b) = 1, then by the Mean Value Theorem, there is a point somewhere in the middle two values of x that f'(x) = 0 since the curve has a degree of more than 2.
