Answer: 4
Step-by-step explanation:
Sqrt x + 3 = 25 : 5
Sqrt x = 5-3
(Sqrt x)^2 = 2^2
X = 4
Answer:
x = ±i, x = -3, and x = -1
Step-by-step explanation:
If x = -1 is a solution, then x + 1 is a factor. Using grouping:
x⁴ + 4x³ + 4x² + 4x + 3 = 0
x⁴ + 4x³ + 3x² + x² + 4x + 3 = 0
x² (x² + 4x + 3) + x² + 4x + 3 = 0
(x² + 1) (x² + 4x + 3) = 0
(x² + 1) (x + 3) (x + 1) = 0
All the solutions are x = ±i, x = -3, and x = -1.
What we're ultimately asking here is how many times 6 goes into 324. The problem becomes a little simpler if we break 324 up into numbers that are easier to work with. 324 = 300 + 24; 6 goes into 300 50 times and 24 4 times, so 6 goes into 324 a total of 50 + 4 = 54 times.
So, the prize-winning pumpkin weighs 54 times as much.
(8/a+4)+(10/b-6)
so common denominator is (a+4)(b-6)
=(8/a+4) *(b-6/b-6)+(10/b-6)*(a+4/a+4)
= 8(b-6) / (a+4)(b-6) + 10(a+4)/(a+4)(b-6)
