(x+5)*7=133
7x+35=133
7x=98
x=98/7
x=14
Answer:
n = -21/4 <em>or </em>-5.25
Step-by-step explanation:
The missing numbers would be 12-6
1. Remove parentheses
-3x^2 + x^4 + x + 2x^4 - 7 + 4x
2. Collect like terms
-3x^2 + (x^4 + 2x^4) + (x + 4x) - 7
3. Simplify
-3x^2 + 3x^4 + 5x - 7
0=-x2+4x-2
+x2-4x+2=+x2-4x+2

x2-4x+2=0
(-4)^2-4(1)(2)
16-8
Final Answer: 8
