Step-by-step explanation:
step 1. what is the question? probably solve for x. okay.
step 2. 4^(2x) + 1 = 4
step 3. 4^(2x) = 3 subtract 1 from each side
step 4. ln4^(2x) = ln3 take on of each side
step 5. 2xln4 = ln3 definition of logs
step 6. 2x = ln3/ln4 divide both sides by ln4
step 7. x = ln3/2ln2^2 divide both side by 2 and replace 4 with 2^2
step 8. x = ln3/4ln2.
Answer:
pLease solve it again but that's answer is 8
Step-by-step explanation:
5x + 2(11 - x) = - 5
5x + 22 - 2x = - 5
3x = - 5 - 22
3x = - 27
x = -27 / 3
x = 9
Therefore x = 9 .
The correct question is
<span>The length of a rectangle if the length is twice the size of the width increased by 1 is it one of the following answers:
A) l= 2w-1
B) l= 2w+1
C) l= 3w
D) none of the choices given
Let
l--------------> </span>length of a rectangle
w-------------> width of a rectangle
we know that
if the length is twice the size of the width increased by 1
l=2w+1
the answer is the option B) l= 2w+1
