Answer:

a² + 4ab + 4b²

Step-by-step explanation:

Given

(a + 2b)²

= (a + 2b)(a + 2b)

Each term in the second factor is multiplied by each term in the first factor, that is

a(a + 2b) + 2b(a + 2b) ← distribute both parenthesis

= a² + 2ab + 2ab + 4b² ← collect like terms

= a² + 4ab + 4b²

What is the sum of the first 20 terms of the series 3 + 14 + 25 + 25 + 36 +

Fynjy0 [20]

Answer:

$S _{20} = 2150$

Step-by-step explanation:

$a _{1} = 3 \\ a _{2} = 14 \\ d = a _{2} - a_{1} = 14 - 3 = 11 \\ n = 20$

$S _{n} = \frac{n}{2} (2a + (n - 1)d) \\ \\ S _{20} = \frac{20}{2} (2(3) + (20 - 1) \times 11) \\ \\ S _{20} = 10 \times (6 + 19 \times 11) \\ S _{20} = 10 \times (6 + 209) \\ S _{20} = 10 \times 215 \\ S _{20} = 2150$

Aysha ran 400 meters in 10 minutes on Monday and she ran 825 meters in 25 minutes on Tuesday. On which day she ran faster?

LiRa [457]

Answer:

Monday

Step-by-step explanation:

Day 1 (Monday):

10 minutes to seconds: 10 x 60 = 600 seconds

$\frac{400m}{600s}$ = 0.67 m/s

Therefore day 1 she ran at 0.67 m/s

Day 2 (Tuesday):

25 minutes to seconds: 25 x 60 = 1500 seconds

$\frac{825m}{1500s}$ = 0.55 m/s

Therefore day 2 she ran at 0.55 m/s

She was faster day 1 (Monday)!
