Answer:
2x² + x - 5
Step-by-step explanation:
(f + g)(x) = f(x) + g(x), thus
f(x) + g(x)
= - 2 + 2x² + x - 3 ← collect like terms
= 2x² + x - 5

Answer:
1/2*6(12+x)=12*x
1/2*(72+6)=12x
36+3x=12x
36=9x
4=x
Step-by-step explanation:
Check that x=4
1/2*6(4+12)=12*4
1/2*(24+72)=48
1/2(96)=48
48=48
So x=4 is the correct answer
Answer:
See attached.
Step-by-step explanation:
Answer: -2x - 10
Steps: -2(x+5)
Apply the distributive law [ a(b + c) = ab + ac ]:
a = -2, b = x, c = 5
-2x + (-2) × 5
Apply minus/plus rules: -2x - 2 × 5
Multiply the numbers: 2 × 5 = 10
-2x - 10
