Answer:

3ax−11a−9x

if $45 is divided into the ratio 4:5 the smaller part is A. $1.50 B.$3.50 C.$4.50 D.$24.50​ Asap

Answers

Answer:

Step-by-step explanation:

When you do 45 divided by 9 you get 5.

                         45 / 9 = 5

     To figure out what the smaller number (in this the 4) equals,

  you have to do 4 times 9 to get 36.

                    4 * 9 = 36

So your answer is 36.

Find the sum of x^2 +3x and -2x^2+9x+5

Answers

x^2 +3x = x ( x + 3 )

2x^2+9x+5 = − ( 2 x + 1 ) ( x − 5 )

Hope this helps you!

Answer:−x^2 + 12x + 5~Well, to get the answer you need to get both equations.Let's start with the equation x^2 +3x or [tex]x^{2} + 3x[/tex].All we need to do is factor the variable 'x' out of ''x^2 + 3x'' to get the answer,  x(x + 3) ~Next we get the other equation, -2x^2 + 9x + 5 or [tex]2x^{2} + 9x + 5[/tex].Simply add and subtract the second term to the expression and factor by grouping to get the answer, −(2x + 1) (x − 5)~Finally, we take both answers from both equations and simplify the expression, and get the final answer, −x^2 + 12x + 5~

Hope you have a good day, Loves!
