Answers
Answer:
x = 3
Step-by-step explanation:
5x + 4 = 19
5x +4 -4 = 19 -4
5x = 15
5x / 5 = 15 / 5
x = 3

a/b = 3
(24 - b) / b = 3...multiply both sides by b
(24 - b) = 3b
24 = 3b + b
24 = 4b
24/4 = b
6 = b
a + b = 24
a + 6 = 24
a = 24 - 6
a = 18
so ur numbers are 18 and 6

We have to determine the complete factored form of the given polynomial
.
Let x= -1 in the given polynomial.
So,
So, by factor theorem
(x+1) is a factor of the given polynomial.
So, dividing the given polynomial by (x+1), we get quotient as .
So, = (x+1)

4 consecutive odd integers whose sum is 232 are : 55, 57, 59, 61
How to find the sum of consecutive integers?
Let the first integer be x and x is an odd number.
Let Four consecutive odd integers are;
x, x + 2, x + 4, x + 6
(x) + (x + 2) + (x + 4) + (x + 6) = 232
4x + 12 = 232
4x = 232 - 12
4x = 220
x = 220/4
x = 55
x + 2 = 55 + 2 = 57
x + 4 = 55 + 4 = 59
x + 6 = 55 + 6 = 61
The numbers are : 55, 57, 59, 61

#SPJ2
x, x + 2, x + 4, x + 6
(x) + (x + 2) + (x + 4) + (x + 6) = 232
4x + 12 = 232
4x = 232 - 12
4x = 220
x = 220/4
x = 55
x + 2 = 55 + 2 = 57
x + 4 = 55 + 4 = 59
x + 6 = 55 + 6 = 61
so ur numbers are : 55, 57, 59, 61

I can tell by looking that there's no easy way to factor the left side,
so we'll have to use the Quadratic formula.
Before doing that, let's just take a look at the discriminant:
( B² - 4AC ) = (9) - (4 x 3 x 1) = (9 - 12) = -3 .
The discriminant is negative, so we know that the roots will be complex conjugates.
Again: x² + 3x + 3 = 0
x = (1/2) [ -3 plus or minus the square root of (-3) ]
x = -3/2 + (1/2) j√3
and
x = - 3/2 - (1/2) j√3
