Answer:
The surface area of the larger prism is 4 times the surface area of the smaller one.
(which agrees with answer B in your list)
Step-by-step explanation:
Notice that the lateral surface area of prisms always consists of parallelograms, whose areas are given by the product base times height. = B x H
Therefore if the dimensions of the prism double, then the base and height of the parallelograms will double as well, making such individual ares of the lateral faces go from:
B x H to --> 2 B x 2 H = 4 (B x H)
that is 4 times the original lateral face's area.
with the faces for the top and bottom bases of the prism, something similar happens, so we conclude that the surface area of the larger prism is 4 times the surface area of the smaller one.
Its -3.5 hope this helpss
Answer:
x=(c-b)/a
Step-by-step explanation:
2w^2 + 44w = 48
w^2 + 22w = 24
w^2 +22w - 24 = 0
w = (-11+sqrt(145)) = 1.0416
The length is about 2w+44 = (46.0832)
Answer:
There are no positive roots
Step-by-step explanation:
The Descartes' rule posits that, given a polynomial with real coefficients ordered, the number of positive roots is equal to the amount of sign-changes OR to such amount minus a number multiple of 2. In you polynomial P(x)=x^3+6x^2+9x+5 you have NO sign-changes, as every coefficient is positive. So, we can confirm that, if the polynomial has real roots, none of these are positive. As 0 can'y be a root of P(x) (replace x=0 and confirm), if there is some root, it will be a negative root. However, the rule can't confirm that there are roots.
