Answer:

Step-by-step explanation:

-14 1/9 is close to - 14

-2 and 9/10 is close to - 3

Let's see what the actual answer is. 40.92222 which is close to 41.

42 is a pretty good estimate.

she went down the slope 10.2 meters, -10.2

then she jumped down to the lake 1.5 meters, -1.5

X2 - 4x + 3 = 0<br> lesser x =<br> greater x =<br> o
Levart [38]

Answer:

lesser x is 1

greater x is 3

Step-by-step explanation:

Here, we want to solve the equation so as to get the bigger and the lesser x values

We proceed as follows;

x^2 -4x + 3 = 0

x^2 - x-3x + 3 = 0

x(x-1) -3(x-1) = 0

(x-3)(x-1) = 0

x = 3

or x = 1

Greater x is 3

lesser x is 1
