How do you solve 3+e^(2x+1)=10

3 + e^(2x+1) = 10 e^(2x+1) = 7 ln [e^(2x+1)] = ln 7 2x + 1 = 1.9459 2x = 0.9459 x = 0.473 Hope this helps...good luck!-3 + e^(2x+1) = 10 e^(2x+1) = 7 2x + 1 = ln(7) 2x = ln(7) - 1 x = (.5)[ln(7

Whats the common denominator of this

(2/x-3) and (3/2x+3)-the two denominators are (x-3) and (2x+3) multiply them together: 2(x^2)-3x-9 is your common denominator. the first fraction must be multiplied by (2x+3) over (2x+3) *this is lik

Find derivative of f(x)=x^2+6x-1 and p(x)=1-x-x^2

Please show the working so I can understand both equations and how you get the answers. Thanks!-derivative of f(x) = 2x +6 derivativeof p(x) = -1-2x

The lateral area of a cone with radius 4cm is 60cm2, what is the slant height

please explain how to answer-lateral area of a cone = pi * radius * slant height => 60 = pi * 4 * slant height => slant height = 60/4pi=4.77cm (use calculator)

What's 2x times 2x.................

Is it 2x² or 4x or 4x²? please explain why if you can-Just because some of the answers are wrong (which is really sad, actually...), I wanted to say that the answer is definitely (2x)*(2x) = (2*2)*(x

2cos^2(2t)=1-cos2t Find all solutions

2cos^2(2t)=1-cos2t Find all solutions-There are infinitely many solutions so we need boundaries, assuming 0 ≤ t ≤ 360. 2cos²(2t) = 1 - cos(2t) 2cos²(2t) + cos(2t) - 1 = 0 [2cos(2t) - 1][cos(2t) + 1]

How would you solve -3.7w= -11.1 and 1/-99y= 0 and 12.5= 4n

I really dont understand how this goes. :/-The first one all you do is divide by -3.7 to create 1 w. w = - 11.1/ - 3.7= 3 The second one is the real devil of the lot. That one is undefined since you
