Because you know the area and that the shape is a square... if the side length is "s"... to find "s" you would say...

s²=1.69

Take the root of both sides and...

s=1.3 km

6(8-x)(x+4)=0 what’s the solution set?

Travka [436]

Answer:

$x_{1} = -4\\\\x_{2} = 8$

Step-by-step explanation:

6(8-x)(x+4)=0

(48 -6x )(x+4) = 0

48x +192 -6x^2 -24x = 0

6x^2 -24x -192=0

using quadratic formula:

$x =\frac{-b+-\sqrt{b^{2}-4*a*c}}{2*a}$

a= 6 b= -24 c= -192

we have:

$x_{1} = -4\\\\x_{2} = 8$

(35+27)÷4×12= what??

Slav-nsk [51]

We have to do BIMDAS

so starting with the brackets we do

35+27

which is 62

62÷4×12

then we work left to right for multiplication and division

62÷4

which is 15.5

then we finish with 15.5×12

which is 186

hope it helps.
