Step-by-step explanation:
The order of operations is a rule that tells the correct sequence of steps for evaluating a math expression. We can remember the order using PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).
7×3 -4(225÷32)×2
7×3 -4(7.03)×2
21 - 8 (7.03)
21 - 56.25
= - 35.25
Answer:
14×6 = 84
7-12 = -5
.°. 7x - 12x is the answer
Step-by-step explanation:
14x²- 5x - 6
14x²- (7 - 12)x - 6
14x²- 7x + 12x - 6
7x(2x - 1) + 6(2x - 1)
(7x + 6) (2x -1)
The answer is D all u had to do was multiply and divide
