Answer:
Common factor from the two pairs
n2+2n-n-2 or
n(n+2)-1(n+2)
Rewrote in factored form
n(n+2)-1(n+2)or
(n-1)(n+2)
Solution
(n-1)(n+2)
Answer:
C.) 7 and A.) 5
Step-by-step explanation:
Constants are numbers with no variable, they have no change, they are "constant"
Coefficients are the opposite, they are the numbers that are with variables and go through some sort of change
Your answer is the Maximum which is A
The answer is 2 hours and 55 minutes. This is because 90 + 85 = 175.
2 hours is equal to 120 minutes thus needing 55 minutes to equal the 175 minutes total.
Answer:
AH = 1 or 4
CH = 4 or 1
Step-by-step explanation:
An altitude divides a right triangle into similar triangles. That means the sides are in proportion, so ...
AH/BH = BH/CH
AH·CH = BH²
The problem statement tells us AH + CH = AC = 5, so we can write
AH·(5 -AH) = BH²
AH·(5 -AH) = 2² = 4
This gives us the quadratic ...
AH² -5AH +4 = 0 . . . . in standard form
(AH -4)(AH -1) = 0 . . . . factored
This equation has solutions AH = 1 or 4, the values of AH that make the factors be zero. Then CH = 5-AH = 4 or 1.
