Perimeter is the sum of all three sides so in this case x+(3x+2)+(3x+2).
They also gave us the perimeter which is 39 so
39= x+(3x+2)+(3x+2)
Simplify so 39=7x+4. [x+3x+3x=7x and 2+2=4]
Then get x by itself so subtract 4 from both sides.
35=7x
Then divide both sides by 7 to get x by itself.
Which leaves us with
X=5

Answer:
arg (w)=π/4 and |w|=√2
Step-by-step explanation:
If z= x+iy is a complex number, then |z| is given by √ ( x²+y² ).
And the argument (z) is given by Ф = tan⁻¹ ( y/x ) where -π < x < π.
Now, in our case w= 1+i i.e. x=1 and y=1.
Therefore, arg (w) = tan⁻¹ (1/1) = π/4 and |w|=√ ( 1²+1² ) = √2 (Answer)
Assuming there is no line under the "less than" sign, this means D + 4 < 7 solves to D < 3, which is what I'm assuming you got. This is found by subtracting 4 from both sides.
Writing D < 3 means D is some number less than 3. A solution is just that. You cannot pick 3 itself because 3 is not less than 3. But you can pick something like 2 since it is less than 3.
D+4 < 7
2+4 < 7 ... replace D with 2
6 < 7 ... true
Or D could be 1
D+4 < 7
1+4 < 7
5 < 7 .... true
and so on.
