"find missing lengths and leave your radicals in simplest form"

simple right triangles

idk what the answer is but for the points

step-by-step explanation:

the first one and the second one that's the answer

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol

60.9774

step-by-step explanation:

because when you add 47.6 plus 7.32 equals 54.92

and when you add .0574 + 6= 6.0574

and when you add 54.92 and 6.0574 you get the answer of 60.9774.
