Answer:
6r+24
Step-by-step explanation:
2(r+3)=2r+6
2(2r+9)=4r+18
(2r+6)+(4r+18)=6r+24

Step-by-step explanation:
<u>Step 1: Define</u>
4(2x - y) - 3x + 2y
<u>Step 2: Simplify</u>
- Distribute 4: 8x - 4y - 3x + 2y
- Combine like terms (x): 5x - 4y + 2y
- Combine like terms (y): 5x - 2y
56*365=20440
56/4=14 (this is how many leap years are within 56 years)
20440+14=20454 days
to find miles per gallon we simply do D/G
D = distance
G = gallons
290/23.2 = 12.5 mpg
225/15 = 15 mpg
Kehinde has better gas mileage.
Answer:
1. 2³ × 2² = (2 × 2 × 2) × (2 × 2) = 23+2 = 2⁵
2. 3⁴ × 3² = (3 × 3 × 3 × 3) × (3 × 3) = 34+2 = 3⁶
3. (-3)³ × (-3)⁴ = [(-3) × (-3) × (-3)] × [(-3) × (-3) × (-3) × (-3)]
= (-3)3+4
= (-3)⁷
4. m⁵ × m³ = (m × m × m × m × m) × (m × m × m)
= m5+3
= m⁸
