Simplify by combining like terms: -4\left(2x-y\right)+y+5\left(x+y\right)−4(2−)++5(+) − 4 ( 2 x − y ) + y + 5 ( x + y ) ; use NO
netineya [11]

Answer:

<em>-3x+10y</em>

Step-by-step explanation:

Given the expression -4\left(2x-y\right)+y+5\left(x+y\right), we are to simplify by combining the like terms. On simplification we have;

= -4\left(2x-y\right)+y+5\left(x+y\right)

Open the parenthesis:

= -4(2x)-4(-y)+y+5(x)+5(y)\\\\= -8x+4y+y+5x+5y

Collect the like terms:

= -8x+5x+4y+y+5y

Sum up the resulting expression

= -8x+5x+4y+y+5y\\= -3x+10y

<em>Hence the required expression on simplification is -3x+10y</em>

Readme [11.4K]
We know that
[surface area of sphere]=4πr²
[surface area of hemisphere]=2πr²

 (sphere)
r=12 in
[surface area of sphere ]=4π12²--------> 576π in²

(hemisphere)
r=12 in[surface area of hemisphere ]=2π12²--------> 288π in²

[the ratio of the surface area of sphere to the surface area of hemisphere]
=576π/288π-------> 2

the answer is
the ratio is 2
