Answer:
62) vertex (-1,-4) x intercepts are (1,0) and (-3,0)
63) vertex (4,-4) x-intercepts are (6,0) and (2,0)
64) vertex (-3,-4) x-intercepts are (-1,0) and (-5,0)
65) vertex (-4,-1) x-intercepts are (-3,0) and (-5,0)
Step-by-step explanation:
Answer: t is 12.5 on a scale drawing
Step-by-step explanation:
(12x5)2+(12x6)2+(6x6)2 will give you the answer. (Subtract 24 from the answer when done)
Answer:
(x+9)(3x+27)
Step-by-step explanation:
3x^2+54x+243 (243×3=729, Product=729, Sum=54) [27+27=54, 27×27=729]
3x^2+27x+27x+243
3x(x+9)+27(x+9)
=(x+9)(3x+27)
Answer:
a^2 + b^2 = c^2 (pythagorean theorem)
a^2 + 40^2 = 41^2 (plug in the known values)
a^2 + 1,600 = 1681 (simplify what you can)
a^2 = 81 (subtracted 1600 from both sides)
a= (81 under a radical) (I think this is what your answer will be, based on the problem)
a=9 (what the fully simplified answer is)
