we are given

it's factor as (x+p)(x+q)
so, we can write as

we can simplify it

now, we can compare both sides
coefficient of x must be equal
so, we get


now, we can look at the table where p+q =3
so, we can see that when p+q=3 .... then p=-2 and q=5
so, option-A.......Answer
Answer:
11.7 Inches
Step-by-step explanation:
9/10 is 0.9, so 3+0.9= 3.9
3.9 x 3 is 11.7 inches, or you can round it to 12 inches or a foot.
P = paddling speed
C = speed of the current
Upstream: 6 = 4 (P - C. Downstream: 6 = 3 (P + C)
4P - 4C = 6
3P + 3C = 6
12P - 12C = 18
12P + 12C = 24
Add the equations:
24P = 42. P = 42/24 = 1.75 mph
Subtract the equations:
-24C = -6
C = 0.25 mph
Answer:
Step-by-step explanation: you multiply 5.38 and 8 and you get the answer 43.04
Answer: x = 15, 95 degress, 85 degrees
Step-by-step explanation:
(2x + 65) + (3x+40) = 180
5x +105 = 180
5x = 75
x = 15
2 (15) +65 = 95 deg
3 (15) +40 = 85 deg
