C because the proportions are equal and multiplied by 4/4
Answer:
L=8
Step-by-step explanation:
S=smaller number
L=larger number
S+L=5 : S=5-L
L=14+2S
substitute for S:
L=14+2(5-L)
solve for L:
L=14+10-2L
3L=24
L=8
Answer:
a) 
b) 
c) 
Step-by-step explanation:
<u>For the question a *</u> you need to find a polynomial of degree 3 with zeros in -3, 1 and 4.
This means that the polynomial P(x) must be zero when x = -3, x = 1 and x = 4.
Then write the polynomial in factored form.

Note that this polynomial has degree 3 and is zero at x = -3, x = 1 and x = 4.
<u>For question b, do the same procedure</u>.
Degree: 3
Zeros: -5/2, 4/5, 6.
The factors are

--------------------------------------

<u>Finally for the question c we have</u>
Degree: 5
Zeros: -3, 1, 4, -1
Multiplicity 2 in -1

Answer: 810 cm^3
Step-by-step explanation:
v= lwh
v= 5 * 9 *18
v= 810
Okay so 300 meters per minute and he ran 8 minutes..
300x8=2400
He still had 600 left to go...
2400+600=3,000
He had to run three times longer than Eric...
3000/3=1000
Does that make sense?
