2x-3(2x-3)+2=45 pls solve fully
mash [69]

Answer:

Step-by-step explanation:

2x*2x=4x^2

2x*3=6x

Keep in mind 4x^2-6x

then next part:

3*2x=6x

3*3=9

6x-9

So totally

(4x^2-6x)-(6x-9)

Minus and minus is equal to +

(4x^2-12x+9)+2=45

4x^2-12x+11=45

-11 on both sides

4x^2-12x=34

X= -17/-2

Sonbull [250]
Hi there! So Andy's total lunch bill was $20 and the drink was 15% of the bill. Percents are parts of 100 and 100 - 15 is 85. That means 85% of the total bill was Andy's food cost. Let's multiply 20 by 85% ti get the cost of his food. 20 * 85% (0.85) is 17. Andy's food costed $17. Here are the answers broken down to be easier to read.

Percent of Andy's bill with food: 85%

Verify the identity. <br><br> tan x plus pi divided by two = -cot x
kogti [31]
Recall that sin(π/2) = 1, and cos(π/2) = 0,

\bf \textit{Sum and Difference Identities}&#10;\\\\&#10;sin(\alpha + \beta)=sin(\alpha)cos(\beta) + cos(\alpha)sin(\beta)&#10;\\\\&#10;sin(\alpha - \beta)=sin(\alpha)cos(\beta)- cos(\alpha)sin(\beta)&#10;\\\\&#10;cos(\alpha + \beta)= cos(\alpha)cos(\beta)- sin(\alpha)sin(\beta)&#10;\\\\&#10;cos(\alpha - \beta)= cos(\alpha)cos(\beta) + sin(\alpha)sin(\beta)\\\\&#10;-------------------------------\\\\&#10;

\bf tan\left(x+\frac{\pi }{2}  \right)=-cot(x)\\\\&#10;-------------------------------\\\\&#10;tan\left(x+\frac{\pi }{2}  \right)\implies \cfrac{sin\left(x+\frac{\pi }{2}  \right)}{cos\left(x+\frac{\pi }{2}  \right)}&#10;\\\\\\&#10;\cfrac{sin(x)cos\left(\frac{\pi }{2}  \right)+cos(x)sin\left(\frac{\pi }{2}  \right)}{cos(x)cos\left(\frac{\pi }{2}  \right)-sin(x)sin\left(\frac{\pi }{2}  \right)}\implies \cfrac{sin(x)\cdot 0~~+~~cos(x)\cdot 1}{cos(x)\cdot 0~~-~~sin(x)\cdot 1}&#10;\\\\\\&#10;\cfrac{cos(x)}{-sin(x)}\implies -cot(x)

If tan of theta =3/4 what is sec of theta​
zhannawk [14.2K]

Answer:

<u>5/4</u>

Step-by-step explanation:

Given :

  • tanθ = 3/4 = opposite/adjacent

Finding the missing side :

  • The hypotenuse must be found
  • √3² + 4²
  • √25
  • 5

Taking the sec ratio :

  • secθ = hypotenuse/opposite
  • secθ = <u>5/4</u>
