I think it’s D is the answer
Answer:
X = 15
Step-by-step explanation:
We move all terms to the left:
<em>x+8+2x-(2x+13)=0</em>
We add all the numbers together, and all the variables:
<em>3x-(2x+13)+8=0</em>
We get rid of parentheses:
<em>3x-2x-13+8=0</em>
We add all the numbers together, and all the variables:
<em>x-5=0</em>
We move all terms containing x to the left, all other terms to the right:
<em>x=5</em>
the answer is number B
Step-by-step explanation:
-4-2<3x+2-2<= 5-2
-6/3<x<=3/3
-3<x<=1
Answer:
Probably 5
Step-by-step explanation:
This is an extremely confusing question. Whoever wrote it most likely had a typo.
The little box in the corner of the triangle means that is 90 degrees. if that is the case, this is a simple question:
Apply pythagorean theorem (a^2 + b^2 = c^2)
In this case:
3^2 + 4^2 = x^2
x^2 = 25
x=5.
HOWEVER: the two given angles are 60 degrees and 50 degrees.
Which does not work. It creates an impossible triangle.
