(x+5)^2 - 64 = 0
(x+5)^2 - 8^2 = 0
(x+5-8) (x+5+8) = 0
(x-3) (x+13) = 0
=> x = 3 or x = -13
=> smaller x = - 13 & larger = 3
So the formula you need for this is
A=1/2bh
So count the squares on the outside of the bottom of the triangle and the left so that would be 7 and 7 so you multiply those together to get 49 then you would divide that answer by 2 and get 24.5 so your answer is 24.5 :)
Look up Pythagorean theorem and it will explain it better than i can click khan academy but basically try drawing a triangle and explain it
Answer:
it would look something like this
Step-by-step explanation:
graph the inequality by finding the boundary line, then shade the appropriate area
