How to solve -12+7x=x
lord [1]

Answer:

x=2

Step-by-step explanation:

So if the equation is -12+7x=x, you need to subtract 7x, because you want to know the value of x. So the equation now looks like this: -12=-6x

you divide-6 to both sides because we want to iscolate the x

The answer is x=2

Hope it helps!

Answer ASAP!
valentinak56 [21]

Answer:

A and D

Step-by-step explanation:

Since tangent is opposite/adjacent,

Tan 40 in this case would be x/3.8 (i used x because we don't know what the value is)

So, you set it up as an algebra problem

Tan40 = x/3.8

Multiply both sides by 3.8

3.8tan40 = x, Option A

And then, angle E is 50 degrees

So tan 50 = 3.8/x

Multiply both sides by x

tan50x = 3.8

Divide both sides by tan50

x= 3.8/tan50

So, A and D are both correct

Which of the following is a solution of x2 + 2x + 4?
RideAnS [48]

Answer:

option-D

Step-by-step explanation:

we are given

x^2+2x+4

Let's assume it is equal to 0

x^2+2x+4=0

We can use quadratic formula

Suppose, we are given quadratic equations as

ax^2+bx+c=0

x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}

we can compare and find a,b and c

a=1 , b=2 , c=4

now, we can plug values

and we get

x=\frac{-2\pm \sqrt{2^2-4\cdot \:1\cdot \:4}}{2\cdot \:1}

now, we can simplify it

and we get

x=-1+\sqrt{3}i,\:x=-1-\sqrt{3}i
