Step-by-step explanation:
-4x+8=42
-4x+8-8=42-8
-4x=34
-4x=34
-4x/-4=34/-4
x= - 17/3
Answer:
2
Step-by-step explanation:
A = P( 1+r/n) ^ (nt)

so n is 2
Answer:
Concept: Mathematical Derivation
- We are given x^2 +6x+2x+12
- Hence we simplify: x^2 + 8x +12
- Now we factor: (x+2)(x+6)
- By mathematical logic we now proved that the roots are x=-2 and x=-6
- Give brainlist and rate positively
