Answer:
a right triangle
is equal to
Step-by-step explanation:
Pythagorean's theorem is a²+b²=c² with c being the longest sides. If it is true then it is a right triangle.
<u>18²</u> + <u>24²</u> = <u>30²</u>
324+576=900
This is true so the triangle is a right triangle
Answer:
A) (-5, -34)
Step-by-step explanation:
f(x) = x^2 + 10x - 9
We complete the square to get the equation in vertex form
Take the coefficient of the x term and divide by 2 then square it. We add it and then subtract it not to change the value of the equation
f(x) = x^2 + 10x +(10/2)^2 - (10/2)^2 - 9
f(x) = x^2 +10x +25 -25 -9
f(x) = (x^2 +10x +25) -34
The term in parentheses simplified to (x+10/2) ^2
= (x+5)^2 -34
= (x - -5)^2 -34
This is in the form (x-h)^2 +k
The vertex is (h,k) h=-5 and k=-34
(-5,-34)
