Which value of "X" is a solution to this equation? 4x2 +22x +10

Mathematics
1 answer:
Maslowich3 years ago
5 0

Answer:

Two solutions: X = -5 and X = -0.5

Step-by-step explanation:

4x^2 + 22x + 10 = 0 // divide by 2

2x^2 + 11x + 5 = 0

delta = 11^2 - 4 * 2 * 5 = 121 - 40 = 81

sqrt(delta) = 9

x1 = (-11 - 9) / 4 = -5

x2 = (-11 + 9) / 4 = -0.5

Three even numbers sum up to 252. the smallest is half the largest and the middle number is 3/4 the largest. what are the three
Mnenie [13.5K]
Let the largest number be x:
smallest number=1/2x
middle number=3/4x
total sum of the numbers is:
x+1/2x+3/4x=252
9/4x=252
solving for x we get
x=252×4/9
x=112
thus the largest number is 112
middle number=3/4*112=84
smallest number=1/2×112=56
Answer: 56,84,112
