Answer:
Only 2 and -5 are roots. Any other number is not a root.
Step-by-step explanation:
The zeros of the function are the x-intercepts and are found by factoring the equations and solving for x using the zero product property.
The f(x) = (x2 - 4x + 4) (x2 + 3x - 10) = 0 can factor into
f(x) = (x -2)(x-2)(x+5)(x-2) = 0.
Set each factor equal to 0 and solve.
x - 2 = 0 so x = 2. This repeats twice.
x + 5 = 0 so x = -5.
So the zeros are 2, -5.
Well 500 reduced by 4 times my age is 232...
The first step to discover the age (I'll assume that's your question) is subtract 232 from 500 500-232 equals 268. Divide this by 4 to get 67. Boy, that's a pretty old age. Hope this helps!
D is the answer because if you calculate the answer correctly. that will be so.
Answer:
Weight of copper: 62,000 lbs. (31 tons). Weight of framework: 250,000 lbs. (125 tons). Weight of concrete foundation: 54,000,000 lbs. Thickness of copper sheeting: 3/32 of an inch, the thickness of two pennies placed together. the answer in 125
