Answer 10

@ikram002p

Answer 11

\(\bf (w+0.09)\cdot w=0.022\implies w^2+0.09w=0.022
\\ \quad \\
\implies w^2+0.09w-0.022=0\implies {\color{blue}{ 1}}w^2{\color{red}{ +0.09}}w{\color{green}{ -0.022}}=0
\\ \quad \\
w= \cfrac{ - {\color{red}{ b}} \pm \sqrt { {\color{red}{ b}}^2 -4{\color{blue}{ a}}{\color{green}{ c}}}}{2{\color{blue}{ a}}}\)

can you keep helping me here? i have 11 questions in 10 min @ikram002p

Answer 15

yes, the hypotenuse will always be the LONGEST side

Answer 16

area =30 =0.5(b) (2b+2)
60=2b^2+2b
b^2+b-30=0
a=1,b=1,c=-30
use the general formula to find b
