X = approximately 633
Steps:
lnx + ln3x = 14
ln3x^2 = 14 : Use the log property of addition which is to multiply same log together so you multiply x and 3x because they have log in common
(ln3x^2) = (14) : take base of e on both sides to get rid of the log
e e
3x^2 = e^14 : e cancels out log on the left side and the right side is e^14
x^2 = e^14 / 3 : divide both sides by 3
√x^2 = <span>√(e^14 / 3) : take square root on both sides to get rid of the square 2 on x
</span>
x = √(e^14) / <span>√3 : square root cancels out square 2 leaving x by itself
x = e^7 / </span>√3 : simplify the √(e^14) so 14 (e^14) divide by 2 (square root) = 7<span>
x = </span>633.141449221 : solve
Coplanar lines are line witch lie on the same lie on the same plane. two parallel lines or two intersecting lines always lie in a plane. Thus, two line are coplanar, if and only if they are either parallel or intersecting. lines in three dimensional space are coplanar, only if they are not skewed lines.
This is all the picture showed omg toooo hard

Step-by-step explanation:
As we know that:
Sum of the measure of all interior angles of a triangle is always 180°.

Answer:
The profit is $24
Step-by-step explanation:
Step one:
given the expression for the profit made as

we are told that p is the number of pens, hence for p= 48 by substituting into the expression we can find the profit as
Step two:
Profit= 1.25p-0.75p,
Profit= 1.25(48)-0.75(48),
Profit= 60-36
Profit=24
