4x − 1 = −2 (x + 1) ⇒ Given
4x−1=−2x−2⇒ Distributive property (since we've multiplied out -2(x+1))
6x−1=−2 ⇒ <span>Addition or Subtraction Property of Equality (We've added 2x onto the 4x to get 6x)
</span>6x=−1 ⇒ <span>Commutative Property (We've moved -1 to the other side to get the sum -2+1 = -1)
</span>x=−¹/₆ ⇒ <span>Multiplication or Division Property of Equality (We divided both sides by 6)</span>
Okay, this is C. This is because since he has already driven 3.5miles so far, we already have that and we add it cause we have already driven that. Then, it says 100 miles for every TWO hours. For x, we need to find how many miles we drive in ONE hour. So: 100/2 miles = 2/2 hours: 50 miles = 1 hr.
Answer:36
Step-by-step explanation:
Answer:
216
Step-by-step explanation:
First find the base area
0.25 * √[(5 + 6 + 5) * (-5 + 6 + 5) * (5 - 6 + 5) * (5 + 6 - 5)] = 12
Equation:
12 * (5 + 6 + 5) + (2 * 12) = 216
