Will mark brainliest! Would also really appreciate it if someone could explain it as well!

Answer:

sin (x) ≥ 0, between 0° and 180° or 0 and π,

sin(x) ≥ 1/2, between 30° and 150° or π/6 and 5π/6

Step-by-step explanation:

This is how I would do it. Subtract sin(x) from both sides

2sin^{2} (x) - sin(x) ≥ 0 , then factor out sin(x)

sin(x) [2 sin(x) - 1] ≥0, then set each factor ≥ 0

sin(x) ≥ 0 and 2 sin(x) - 1 ≥ 0

sin (x) ≥ 0, between 0° and 180° or 0 and π

2 sin(x) ≥ 1

sin(x) ≥ 1/2, between 30° and 150° or π/6 and 5π/6

Solve. 2x2 + 14x = −24 A) x = 2, x = 3 B) x = 3, x = 4 C) x = −2, x = −3 D) x = −4, x = −3
Aleksandr [31]

Answer:

<em>Answer is option d</em><em>)</em><em> </em><em>x</em><em> </em><em>=</em><em> </em><em>-4</em><em> </em><em>,</em><em> </em><em>x</em><em> </em><em>=</em><em> </em><em>-3</em>

Step-by-step explanation:

given \: equation \: is \\ 2 {x}^{2}  + 14x =  - 24 \\ 2 {x}^{2}  + 14x + 24 = 0 \: \\  dividing \: this \: equation \: by \: 2 \: we \: get \\  {x}^{2}  + 7x + 12 = 0 \\ by \: factorization \\ (x + 4)(x + 3) = 0 \\ x =  - 4 \:  \:  \:  \:( or) \:  \:  \: x =  - 3

The expression n2 + n represents the total number of blocks used in the nth figure of a pattern. Use the equation n2 + n = 56 to
Brrunno [24]

We have to solve this quadratic equation n^{2}+n=56 for n to get <em>which figure has 56 blocks</em>.

n^{2}+n=56\\n^{2}+n-56=0

For middle term factorization, we need <em>two numbers that multiplied gives us -56 and added gives us 1 (coefficient of n).</em>

<em>Such two numbers are </em><em>8</em><em> and </em><em>-7</em><em>. We can now write,</em>

<em>n^{2}+n-56=0\\(n+8)(n-7)=0\\n=-8, 7</em>

<u><em>"There is no negative figure number possible, so we disregard -8"</em></u>

Our answer is 7.


ANSWER: The 7th figure has 56 blocks.
