Solve for x :
4 - (2x + 4) = 5
1) x = -10
2) x = 5/2
3) x = 1/2
4) x = 6
<h3><u>Answer</u><u>:</u><u> </u></h3>
➛ 4 - 2x + 4 = 5
➛ 2x + 4 - 4 = 5
➛ 2x + 0 = 5
➛ 2x = 5
➛ x = 5/2
Thus, The value of x is <u>5/2</u><u>.</u><u> </u>
Answer:
The value of x is -9, 3/4 and 3.
Step-by-step explanation:
In order to find the value of x, tou have to let f(x) equals to 0 :
Let f(x) = 0,
(x-3)(x+9)(4x-3) = 0
x - 3 = 0
x = 3
x + 9 = 0
x = -9
4x - 3 = 0
4x = 3
x = 3/4
Answer:
B.2 1/41
Step-by-step explanation:
In a perfect square trinomial of the form ax+bx+c where a, b and c are constants, the value of (b/2)²=ac
In the provided equation the value of a=1, b=-3 c=?
Therefore, (-3/2)²=c since a-the coefficient of x²=1 and 1×c=c
c=2.25= 2 1/4
Thus the trinomial x² - 3x + 2 1/4 is a perfect square.
