Answer:

3a² + 13ab - 10b²

Step-by-step explanation:

(3a - 2b)(a + 5b)

Each term in each bracket multiplies each term in the other bracket.

3a(a + 5b) -2b(a + 5b)

3a² + 15ab - 2ab - 10b²

aalyn [17]

Answer: 111.4m

Explanation:

1) Trigonometric ratios

You only need to use tangent ratio.

tangent ratio = opposite-leg / adjacent-leg = balloon height / horizontal distance

2) First, find the height of the ballon when he is watching at an angle of elevation of 28°

tangent ratio = opposite-leg / adjacent-leg = balloon height / horizontal distance

tan(28°) = balloon height/65m ⇒balloon height = tan(28°)×65m

balloon height = 34.56m

3) Second, find the height of the balloon,when he is watching at an angle of elevation of 66°

tan(66°) = height of the balloon / 65m ⇒ height of the balloon = tan(66°)×65m

height of the balloon = 145.99m

4) Vertical distance the balloon ascended while Charlie watched.

Subtract the final initial height from the final height:

145.99m - 34.56m = 111.43m

4) Round to the nearest tenth: 111.4 m

Please send more context as of the "green numbers".

For the multiplication,

i 49 x 10 = 490
490 ÷ 10 = 49

ii 2.3 <span>÷ 10 = 0.23
0.23 x 10 = 2.3

iii 0.034 x 1000 = 34
34 </span><span>÷ 1000 = 0.034

iv 876 </span><span>÷ 100 = 8.76
8.76 x 100 = 876

Hope this helps :)</span>
