Answer:

see explanation

Step-by-step explanation:

Using the rule of exponents

a^{m} × a^{n} ⇔ a^{(m+n)}

49

3b × 4b³ = (3 × 4) × b^{(1+3)} = 12b^{4}

50

5x² × 8x × 5x³

= (5 × 8 × 5) × x^{(2+1+3)} = 200x^{6}

The sum of x and 8 is less than 72​
Vanyuwa [196]

Answer:

x<84

Step-by-step explanation:

First, write an inequality. We know it is not an equation because of the words "less than". Also, x and 8 are being added because of the word "and". Here's the inequality: x+8 < 72. Now, subtract 8 on both sides so x is isolated. Our simplified inequality looks like this: x < 84.

If you replace the x with 11, the new equation would be 10+5(11)=65. First, multiply 5 and 11, your answer would be 55, then add the ten, you would get 65. Which makes the equation true, because 65=65.
I hope this helps

Finding angles , please help
jek_recluse [69]

Answer:

  • m∠C = 43.6°, m∠B = 107.4°, b = 51.2

Step-by-step explanation:

<u>Use the law of sines:</u>

  • a / sin ∠A = c / sin ∠C
  • 26 / sin 29° = 37 / sin ∠C
  • sin ∠C = 37 sin 29° / 26
  • sin ∠C = 0.6899
  • m∠C = arcsin 0.6899
  • m∠C = 43.6°

<u>Find the missing angle:</u>

  • m∠B = 180° - 29° - 43.6° = 107.4° (rounded)

<u>Use the law of sines to find the length of b:</u>

  • a / sin ∠A = b / sin ∠B
  • 26 / sin 29° = b / sin 107.4°
  • b = 26 sin 107.4° / sin 29°
  • b = 51.2 units (rounded)
