Answer:
the answer is 60 x 10^3 in scientific notation
Step-by-step explanation:
Answer: I think it’s D
Step-by-step explanation:
it’s because 8^2 + 13^2 equals 233 and when square rooted equals 15.26 not 20 so no.
Do 178 times 28 which equals 4,984 then you do 4,984 decided by 7 which equals 712 because there are 7 days a week. So the answer is 712.
The two values of roots of the polynomial 
are 
<u>Solution:</u>
Given, polynomial expression is
We have to find the roots of the given expression.
In order to find roots, now let us use quadratic formula.
Given that
Here a = 1, b = -11 and c = 15
On substituting the values we get,
Hence, the roots of given polynomial are
Let b and h represent the length of the side of the base and the slant height, respectively. Then the total surface area is
A = b² + 4*(1/2)bh
A = b² +2bh
Substituting the given numbers, you have
336 = 12² +2·12·h
192 = 24h . . . . . . . . . subtract 12² = 144
8 = h . . . . . . . . . . . . . divide by 24
The slant height is 8 inches.
