Answer:
Step-by-step explanation:
(x⁴+ax²+b) ÷ (x+1) = x³-x²+(a+1)x-(a+1) remainder b+(a+1)
Since x+1 is a factor, b+(a+1) = 0.
(x³-x²+(a+1)x-(a+1)) ÷ (x+2) = x²-3x+(a+7) remainder -3a-15
Since x+2 is a factor, -3a-15 = 0
a = -5
b = 4
x⁴+ax²+b = x⁴ - 5x² + 4 = (x²-4)(x²-1) = (x+2)(x-2)(x+1)(x-1)
The 30th caller because you have to find a common "denominator" for both numbers. 10 multiplied by 3 is 30 and that person will win both prizes
She will need 5 and a half hours. First step is to do 360-112.5 the pgs she read and her goal. then you'll get 247.5. To find how many hours you need to find the unit rate. so 247.5 divided by 45 is 5.5 hours.
hope this helped. can u mark me as the brainiest answer
The coordinates of R are (6,9)
Step-by-step explanation:
Given
S(6,7) = (x2,y2)
R = (x1,y1)
M = (6,8)
The formula for mid-point is:

Putting values

Putting respective coordinates equal

Hence,
The coordinates of R are (6,9)
