Answer:
1.8
Step-by-step explanation:
Hello :
<span>A(-2, -5), B(-3, 2), and C (1, -2)
calculate : AB² , AC² ,BC²
</span> AB² = ( -3 +2 )² + ( 2 +5 )² =50
AC² = ( 1 +2 )² + ( -2 +5 )² =18
BC² = ( 1 +3 )² + ( -2 - 2 )² = 32
by petagor rule : AB² = AC² + BC²....(<span>ABC is a </span>right triangle in : C )
Answer:
x^2(x – 9) + 5(x – 9)
Step-by-step explanation:
x^3 – 9x^2 + 5x – 45
To factor by grouping, we can take out an x^2 out of the first group of 2 terms
x^2 ( x-9) + 5x -45
We can take out a -5 out of the last 2 terms
x^2 ( x-9) + 5( x-9)
Good morning

Answer:
2/3 < 3/4
___________________
Step-by-step explanation:
2/3 = (2*4)/(3*4)=8/12
3/4 = (3*3)/(4*3)=9/12
Since 9/12>8/12 then 3/4>2/3

Answer:
x = 3
Step-by-step explanation:
x^2 - 9 = (x+3)(x-3)
[(x + 3)*(x -3] /x+3) = x-3
x - 3 = 0
x = 3
