5 7/8 - 2 9/10

we can make 5 7/8 into an improper fraction of 47/8

we can also make 2 9/10 into an improper fraction of 29/10

find a common multiple between the denominators 10 and 8 - the smallest would be 40

47/8 will be made into 235/40

29/10 will be made into 116/40

235/40 - 116/40 = 119/40

simplify 119/40 and you get 2 39/40

decimal form is 2.975

If two sides in one triangle are 9 and 21 , then the third side might be
slamgirl [31]

Answer:

13

Step-by-step explanation:

there is a rule that says that if you add any 2 sides, it should be more than the third. 9+21 is greater than 13. 21+13 is greater than 9. 13 is the only number which if you add 9 to it it will be greater than 21. 12 will equal 21, but it still wont work.

hope this helps :))

Which equation represents the polynomial function with zeros −1, 1, and 3 (multiplicity of 2), and a y-intercept of −18? (4 poin
Vlad [161]
Correct Answer:
3rd option is the correct answer

Solution:
The zeros of the polynomial are -1,1 and 3. The multiplicity of 3 is 2. So the polynomial can be expressed as:

y=a (x-3)^{2}(x-1)(x+1)

The y-intercept of the polynomial is -18. This means the polynomial passes through the point (0,-18). Therefore, y must be -18 when x = 0. Using these values of x and y in previous equation we get:

-18=a (0-3)^{2}(0-1)(0+1) \\  \\ 
-18=-9a \\  \\ 
a=2

The final equation of the polynomial becomes:

y=2 (x-3)^{2}(x-1)(x+1)
