Answer:

  • (12, 12, 156) and (9, 9, 162)

Step-by-step explanation:

<u>Since AB = AC and the triangle is isosceles:</u>

  • ∠ABC ≅ ∠ACB
  • 3x² - 2x + 4 = 9x - 6
  • 3x² - 11x + 10 = 0
  • x = (11 ± √(121 - 4*3*10)/6
  • x = (11 ± 1) / 6
  • x = 2, x = 10/6

<u>The angles:</u>

  • m∠B = m∠C = 9*2 - 6 = 12°
  • m∠A = 180 - 2(12) = 156°

  • m∠B = m∠C = 9(10/6) - 6 = 9°
  • m∠A = 180 - 2(9) = 162°

Can somebody help me with this
neonofarm [45]

The sum of the expression (–x² + x) and (x² – 3x – 1) will be –2x – 1. Then the correct option is D.

<h3>What is Algebra?</h3>

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

The expression can be written as

(–x² + x) and (x² – 3x – 1)

Then the sum of the expression (–x² + x) and (x² – 3x – 1) will be

(–x² + x) + (x² – 3x – 1) = –2x – 1

Then the correct option is D.

Two thirds of a number reduced by 11 is equal to 4 more than the number. Find the number. n= Answer
Ira Lisetskai [31]

Answer:

-45

Step-by-step explanation:

2/3x - 11 = x + 4

  • I created an inequality representing the above statement first. This makes things look less complicated than what the question is asking.

2/3x = x + 15

  • solve for x. I started by adding 11 to both sides.

-1/3x = 15

  • multiply both sides by -3

x = -45
