Answer:

4

Step-by-step explanation:

use the Pythagoras' theorem

formula for an ABC triangle( right angled)

AB is height

BC is hypotenuse

CA is length

BC^{2} = AB^{2} + CA^{2}

in your case

AB is 7

BC is 8

CA is unknown so we write x

8^{2}=7^{2}+x^{2}

64=49+x^{2}

64-49=x^{2}

15=x^{2}

\sqrt{15} =x

3.87=x

4=x

Theres only one way, but if you're putting it as a decimal then you just divide 7 from 3 to get your answer

•So, 7 ÷ 3 = 2.3
•And 2(3) + 1 = 7 / 3 (if that makes sense)

Answer:  " -2y³ + 3y²<span> + 27y " . 
_______________________________________________________
Refer to the completed chart below (image attached).</span>
_______________________________________________________
Using the completed chart below (image attached), we can write out the terms:
__________________________________________________
  y³ − 3y³ + 9y² + 3y² − 9y² + 27y ;

Then, we can combine the "like terms" ;
__________________________________________
y³ − 3y³  = -2y³ ;

+9y² + 3y² − 9y² =  + 3y² ;
___________________________________________________________
to get:  -2y³ + 3y² ;   and bring down the "+27y" ;
