Answer:
<em>x</em><em> </em><em>=</em><em> </em><em>3</em>
Step-by-step explanation:
First open the brackets. While opening brackets, you've to be careful about signs. So when you open bracket of <em>(</em><em>1</em><em>5</em><em>-</em><em>x</em><em>)</em>, there's <em>negative</em> sign in front of it, so it makes the signs inside the brackets to change. Then you solve the it.
Answer:

Answer: 360/15=24 sides
Step-by-step explanation:
Must be 16 and 21 because we can see
30 and 70 has 10 as factor
24 and 44 has 2 as factor
12 and 30 has 2 as factor and all those factors are greater than one
Answer:
n = -4
Step-by-step explanation:
Step 1 :
Equation at the end of step 1 :
((6n - 2 • (4n + 7)) + 4) - -2 = 0
Step 2 :
Step 3 :
Pulling out like terms :
3.1 Pull out like factors :
-2n - 8 = -2 • (n + 4)
Equation at the end of step 3 :
-2 • (n + 4) = 0
Step 4 :
Equations which are never true :
4.1 Solve : -2 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation :
4.2 Solve : n+4 = 0
Subtract 4 from both sides of the equation :
n = -4
One solution was found :
n = -4
