Making R, the subject of formula;
Answer:
-40 < x < 20
Step-by-step explanation:
step 1: -12 < 1/2(x+16) < 18 --> Distribute
step 2: -12 < 1/2x + 8 < 18 --> subtract 8
step 3: -20 < 1/2x < 10 --> Multiply by 2
answer : -40 < x < 20
Answer:
(x-3) (x-4)
Step-by-step explanation:
x²- 7x + 12
= x² - 3x -4x +12
=x(x-3) - 4(x-3)
=(x-3) (x-4)
