Answer:
the answer would be -13n-23
Step-by-step explanation:
first you want to distribute the brackets
-7(2+n) = -14-7n
+(-9-6n)
-9-6n
-14-7n-9-6n
combine the n value with an n value and an integer that doesn't have an n value
-7n-6n-14-9
= -13n-23
<span>By similarity of triangles we have the following relationship:</span>
<span> (x) / (6) = (18) / (9)</span>
<span> Simplifying we have:</span>
<span> (x) / (6) = 2</span>
<span> Clearing the value of x we have:</span>
<span><span> x = 6 * 2</span></span>
<span><span> X = 12</span></span>
<span><span> Answer:</span></span>
<span><span> The value of x for this case is equal to:</span></span>
<span><span> <span>X = 12</span></span>

Answer:
-2y +2
Step-by-step explanation:
(x - y + 1) - (x + y - 1)
Distribute the minus sign
(x - y + 1) - x - y + 1
Combine like terms
x-x -y-y +1+1
-2y +2
Answer:
4(x + 5) = 2(10 / x) solved = - 20
Step-by-step explanation:
this may not be correct but i really think im right
Writing it in the form of a+bi we get 0+4i
Step-by-step explanation:
We need to evaluate expression -16 squared and write the result in form a+bi
The given expression is: 
We know that 
We know that 16= 4x4 = 4^2
Putting values:
So, Writing it in the form of a+bi a=0 and b=4 so, 0+4i
