Cavalieri's principle states that if two solids of equal height have equal cross-sectional areas at every level parallel to the respective bases, then the two solids have equal volume.
Answer:
(x + 7) (x - 3)
Step-by-step explanation:
Find 2 numbers that add to 4 and multiply to -21
(x + 7) (x - 3)
1.a
2.d
3. they all are the same type of number, real rationals
4. No irrational number is a rational number
5.No irrational number is a integer
Y = x^2 + 10x - 171
y = (x - 9)(x + 19)
x - 9= 0 x + 19 = 0
x = 9 x = -19
Answer B covers all requirements... the factored form is
y= (x + 19)(x - 9)
and the zeros are -19 and 9
