HELP ASAP!!!!!!!!!!!!!! WILL MARK BRAINLIEST PICTURES BELOW!!!!!!!!!!!!!!!!!!!!!!!!!
harkovskaia [24]

5. 6√3

6.  x = 10√3     y = 30

7. x = 34    y = 17√3

8. 30

9. SinA = 3/5       CosA = 4/5

10. Tan20 = 9/x

Multiply both sides by x to get it on the other side

x(tan20) = 9

Divide 9 by tan20 to get x.

x = 9/tan20

x = 24.7

Perform the indicated operation to write given polynomial in standard form: (x+ 2)(2x^2 − 5x+7)
Elan Coil [88]

Answer:

So the expression in standard form will be 2x^3-x^2-3x-14        

Step-by-step explanation:

We have given expression (x+2)(2x^-5x+7)

We have to write this expression in standard form

For writing in standard form first we have to multiply the expression

So after multiplication number (x+2)(2x^2-5x+7)=2x^3-5x^2+7x+4x^2-10x-14=2x^3-x^2-3x-14

So the expression in standard form will be 2x^3-x^2-3x-14
