Answer:

-3=x

Step-by-step explanation:

First you must add the X's on each side which gives you: 1x-2= -x - 4 - 4

Next you must add the first number 4 to the - 2 on the other side.

Then you do the exact same thing with the other number 4.

After that you get 1x+6=-x, then you subtract the 1 x with the -x to get 6= -2x.

Finally divide  both sides by 2 and your final answer is -3 = x

A square patio has an area of 170 square feet. How long is each side of the patio to the nearest tenth?
Pavlova-9 [17]
Since we know that squares have the same length on all sides, you would find the square root of 170
√170=13.03840481
rounded to the nearest tenth would be 13.1

You can check your work by multiplying 13.1 by 13.1 which equals 170.3

I try to explain the problem and give the answer, I hope this helps!

Help plz I need to fin before today help

Answer:

BD = 12.1 (nearest tenth)

Step-by-step explanation:

∆ABC is an isosceles triangle, since it has two equal sides, AB and BC. Also, this means that <BAD and <BCD = 60° each.

BD divides ∆ABC into two equal parts.

Apply trigonometric ratio to find BD.

Reference angle = <BAD = 60°

Adjacent = AD = 7

Opposite = BD

Thus, we would have:

tan 60 = opp/adj

Tan 60 = BD/7

7*Tan 60 = BD

12.1 = BD

BD = 12.1 (nearest tenth)
