Using S = ut + 1/2gt², from rest, u = 0

S = 1/2gt², g ≈ 9.8 m/s²

S = 1/2 *9.8*3²

S = 0.5 *9.8*3*3

S ≈ 44.1 m

How do you simplify, explain -3√7 -3√7 -2√32

andreev551 [17]

Since the first two numbers have the same radical, they can be combined.
-3√7-3√7=-6√7
Simplify -2√32 to get -8√2.

So simplified, you would get -6√7-8√2.

What is the solution for 2y=x+2 x-3y=-5

Mars2501 [29]

Answer:

x = 4

y = 3

Step-by-step explanation:

Given equations :-

2y = x + 2
x - 3y = -5

Second equation can be written as ,

x - 3y = -5
-3y = -x - 5

Adding them :-

-3y + 2y = 2 -5
-y = -3
y = 3

Put this in (ii) :-

x = 3y - 5
x = 3*3 - 5
x = 9 -5
X = 4
