Answer: 133.63 square units

Step-by-step explanation:

Pythagoras theorem = a^2+b^2=c^2

10^2 + b^2 = 18^2

b = sqrt (324-100)

b = sqrt 224

Height is to 20 what 10 is to sqrt of 224

h/20 = 10/sqrt 224 (cross multiplication)

h*sqrt 224 = 10*20

h*sqrt 224=200

h = 200/sqrt 224 (200/sqrt 224 = (200*sqrt 224)/200) = 13.36 (height)

Area = (base times height divided by two)

Area = (13.36*20)/2 = 133.63

I can’t figure out the solution I think it is y < -10

Olenka [21]

Hey there!

<em>With negatives ( $-$ ) you have to switch your symbol to the other way</em>
$\bold{\frac{y}{-2}\leq5}$
Firstly, substitute the $\bold{y\ value }$ as an invisible 1
So, now we have to flip the equation around
$\bold{\frac{-1}{2}y\leq5}$
We have to $\bold{multiply}$ by $\bold{-2}$ on each of your sides
$\bold{-2\times\frac{-1}{2}\leq-2\times5}$
$\bold{Cancel \ out:2\times\frac{-1}{2}y \ because \ it \ equal \ 1}$
$\bold{Keep: -2\times5 \ because \ it \ helps \ us \ find \ our \ answer}$
$\bold{-2\times5=-10}$
$\boxed{\boxed{\bold{Answer:y\geq-10}}}\checkmark$

Good luck on your assignment and enjoy your day!
