2x^2 - 2x - 40 = 2x^2 -10x + 8x - 40 = 2x(x - 5) + 8(x - 5)
= (x-5)(2x+8) = 2(x-5)(x+4)
Answer:
Bruh i got correlation hw that i posted on here too and nobody helped lol.
Step-by-step explanation:
y-y1 = m(x-x1)
y-1 = 4/5 (x+2)
y-1 = 4/5x +14/5
y = 4/5x +9/5
Should be your answer but feel free to check back with me (i'm not 100% sure)
<span>When given 3 triangle sides, to determine if the triangle is acute, right or obtuse:1) Square all 3 sides.36, 27, 61

<span><span>2) Sum the squares of the 2 shortest sides.1,296 + 729 = 2,025
3) Compare this sum to the square of the 3rd side.2,025 < 3,721
if sum > 3rd side² Acute Triangleif sum = 3rd side² Right Triangleif sum < 3rd side² Obtuse TriangleTherefore, it is an Obtuse TriangleSource:http://www.1728.org/triantest.htm
