Answer: 5a + 5b + 5 - x(a + b)
Step-by-step explanation:
(a + b + 1)2 – (a + b + 1)(x - 2) + (a + b + 1)
2a + 2b + 2 - (ax - 2a + bx -2b -2) + (a + b + 1)
2a + 2b + 2 - ax + 2a - bx +2b +2 + a + b + 1
5a + 5b + 5 - x(a + b)
Answer:
-47

Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify</em>
a⁴ - 6b + 3b ÷ ac
<em>a</em> = -2
<em>b</em> = 6
<em>c</em> = 3
<u>Step 2: Evaluate</u>
- Substitute in variables: (-2)⁴ - 6(6) + 3(6) ÷ (-2)(3)
- Exponents: 16 - 6(6) + 3(6) ÷ (-2)(3)
- Multiply: 16 - 36 + 18 ÷ (-2)(3)
- Divide: 16 - 36 - 9(3)
- Multiply: 16 - 36 - 27
- Subtract: -47
