Answer:
C. Yes Devon should have evaluated f(3).
Step-by-step explanation:
She substituted the wrong value. For x - 3 to be a factor f(3) must equal 0.
f(3) = 3^3 + 3^2 - 10(3) + 8 = 27 + 9 - 30 + 8
= 14, so x- 3 is not a factor anyway but she did substitute the wrong value.
The is number 3 or c. I hope this helps.
2l+2w=perimeter <= equation for perimeter
<span>w+4=l <=length is 4 greater than width </span>
<span>2w+2(w+4)=24 <= plug in the l in the first equation with the second equation </span>
<span>2w+2w+8=24 <= solve the equation </span>
<span>4w=16 </span>
<span>w=4 </span>
<span>and, since </span>
<span>w+4=l <= length is 4 greater than width </span>
<span>then l=4+4 </span>
<span>l=8</span>
17(k + 6) > 3(5k + 4)
17(k) + 17(6) > 3(5k) + 3(4)
17k + 102 > 15k + 12
- 17k - 15k
2k + 102 > 12
- 102 - 102
2k > -90
2 2
k > -45
Answer:
C
Step-by-step explanation:
The correlation is becoming stronger, with a negative direction.
The closer a number is to the zero in the number line when its negative the more value it has.
Now if the number is negative and its away from zero in the number line the less value it has.
