You are multiplying. If you have the problem 3x, then this is 3 multiplied by the number x. But this does not work for regular numbers. If you tried to combine 3 and 4, you would have 34 which is nothing more than thirty-four. Hope this helps!

(Find the length of the missing side in each triangle)

Answer:

see attached

Step-by-step explanation:

The relevant trig relations are summarized by the mnemonic SOH CAH TOA. This means ...

Sin = Opposite/Hypotenuse

Cos = Adjacent/Hypotenuse

Tan = Opposite/Adjacent

So, for each triangle, determine the relationships of the given sides to the given angle: adjacent, opposite, or hypotenuse. Then write and solve the equation using one of the above templates.

Complete the table below to solve the equation $2x + 12 = 4^x$

IrinaVladis [17]

2(2) + 12 = 4^(2)
4 + 12 = 16
16 = 16

only x = 2 will have f(x)=g(x) so x = 2 is answer

What are the potential solutions to the equation 2ln(x+3)=0

skad [1K]

$2\ln(x+3)=0\implies \ln(x+3)^2=0\implies e^{\ln(x+3)^2}=e^0\implies (x+3)^2=1$

Expanding the left side gives

$x^2+6x+9=1\implies x^2+6x+8=0\implies (x+4)(x+2)=0$

which gives two solutions, $x=-4$ and $x=-2$ . But if $x=-4$ , then $\ln(x+3)=\ln(-1)$ , but this number isn't real, so $x=-4$ is an extraneous solution. Meanwhile if $x=-2$ , you get $\ln(-2+3)=\ln1=0$ , so this solution is correct.

"Potential solutions" might refer to both possibilities, but there is only one actual (real) solution.

How do you find the x-intercept in sentences?

yulyashka [42]

Answer:

To find the x-intercept of any equation, set the y-value to 0.

Step-by-step explanation:

Example:

y=1x+4

To find x-intercept:

0=1x+4

1. Subtract 4 from both sides

2. Divide both sides by 1

The x-intercept is -4
