Step-by-step explanation:

(9x^2+2x-11)-(11x-7x^2+3)-(5+7x)

distribute the minus sign

9x^2+2x-11-11x+7x^2-3-5-7x

Combine like terms

9x^2+7x^2-7x+2x-11x-3-5-11

Answer:

16x^2 - 16x - 19

Step-by-step explanation:

(9x^2+2x-11)-(11x-7x^2+3)-(5+7x)    (Distribute the negative signs and open the parenthesis to start adding like terms)

9x^2 + 2x - 11 - 11x + 7x^2 - 3 - 5 - 7x    (Simplify)

16x^2 - 16x - 19

To solve this question, simply use the formula to find the volume of the cylinder,

V = Pi r^2 • h

V = 3.14 • 4^2 • 4.

Then compare the value for volume to the closest number on the number line. Is it in between 2 numbers, exactly one number on the number line or very close to one number as in the number line.

Please help me answer the question 9 though 10
olchik [2.2K]

Answer:

9) slope of AC = slope of FH

Equation of the line is y = - x + 5

10) Area = 320

Step-by-step explanation:

For 9, the only thing similar IS the slope of the hypotenuse because the triangles are along the same line. Unless they're asking for the equation of the line, then that's just using the point slope equation which is:

y = - x + 5

For 10, just multiply 4 and 5 by 4 to get 16 and 20. Then multiply 16 and 20 to get 320.
