Step-by-step explanation:
2*
2*9=18
1 second = <span>0.000000001 Giga seconds
500 * </span>0.000000001 = <span>0.0000005 Giga seconds</span>
Answer:
x = - 3
Step-by-step explanation:
Given
3(2x + 4) = - 6 ( divide both sides by 3 )
2x + 4 = - 2 ( subtract 4 from both sides )
2x = - 6 ( divide both sides by 2 )
x = - 3
Answer:
<u>180 miles</u>
Step-by-step explanation:
- Ann's car can go 288 miles on 8 gallons
<u>Base rate</u>
- = No. of miles / No. of gallons
- = 288 / 8
- ⇒ 36 miles per gallon [Important to rememeber!]
<u>5 gallons</u>
- Distance for 5 gallons = base rate x 5
- Distance = 36 x 5
- Distance = <u>180 miles</u>
Answer:
(n+5)² - (n+3)² =
= (n² + 10n + 25) - (n² + 6n + 9)
= n² + 10n + 25 - n² - 6n - 9
= 4n + 16
= 4(n + 4) ⋮ 4
