Answer:
<u>Step-by-step explanation:</u>
I am going to use Synthetic Division.
The divisor is: x + 2 = 0 → x = -2
The coefficients are: 1x³ + 0x² + 0x - 6 → 1, 0, 0, -6
-2 | 1 0 0 -6
<u>| ↓ -2 4 -8 </u>
1 -2 4 -14 ← remainder
Reduced Polynomial is: x² -2x + 4 - 14/(x + 2)
Distance = speed * time
for curtis d = st = 6t (where t is the time that he walks)
sean walks 20 seconds longer than curtis so we have the equation
d = s(t+20) = 5(t+20)
as the distances are the same we have
So sean has walked 100+20 = 2
6t = 5(t+20)
6t = 5t + 100
t = 100
so Sean walks 120 seconds when they had both walked the same distance.
Answer:
The answer is B
Step-by-step explanation:
Answer:
The correct option is (A).
Step-by-step explanation:
The expression Carey is solving is:
Simplify the expression as follows:
So, in Carey's calculation the third step is incorrect.
Instead of 27 the three-fourth must be multiplied by 36 to get the correct answer.
Thus, the correct option is (A).
scale factor=shadow: real figure
s.f=4:6
=2:3
applying the same to the pole
let x be the real height of the pole.
2:3=20/x
3×20=2x
60=2x
60/2=2x/2
x=30feet
