bixtya [17]
<h3><em>Hey! </em></h3>

<u>let the numbers be n and m</u>

<u>n+m=65</u>

<u>n=4m</u>

<em>So when we put our work in:</em>

<u>4m+m=65</u>

<u>5m=65</u>

<u>m=13</u>

<u>n=52</u>

So therefore your two numbers are 52 and 13!

<em>Hope this helped! °ω°</em>

Prove (x+y)^2=x^2+2xy+y^2
Scrat [10]
Rules of exponents and the distributive property apply.
  (x+y)² = (x+y)·(x+y) . . . . . meaning of exponent of 2
  = x·(x+y) +y·(x+y) . . . . . . . distributive property
  = x·x +x·y +y·x +y·y . . . . . distributive property
  = x² +x·y +x·y +y² . . . . . . meaning of exponent of 2, commutative property of multiplication
  = x² +(1+1)·x·y +y² . . . . . . distributive property
  = x²+2xy+y² . . . . . . . . . the desired form
Thus
  (x+y)² = x²+2xy+y²

Can someone please give me the answers to this? ... please ...
Darina [25.2K]

Step-by-step explanation:

anyway, without any further information about ground consistency, friction and stuff, we have to assume ideal circumstances.

so, the same energy that made the ball flying through the air makes it also bounce or roll across the ground carrying it exactly the same distance at the same time.

the distances with an ideal, reflective ground will be the same.

it is the same energy released with the same inertia.
