The answer for your question is -3
So I am pretty sure the answer is never. Hope this helps.
Good luck mate :P
Answer:
X = 1/2 and X = 5/4
Step-by-step explanation:
7x^2 - 14x + 5 = -x^2
8x^2 - 14x + 5 = 0
(2x - 1) + (4x - 5) = 0
To find X1
2x - 1 = 0
2x = 1
x = 1/2
To find X2
4x - 5 = 0
4x = 5
x = 5/4
Answer:
first option
Step-by-step explanation:
Angles ABC and GFH are a pair of alternate exterior angles of these two parallel lines cut by a transversal. This means they are congruent (properties of two parallel lines cut by a transversal).
Set them equal to each other to find x.
10x + 20 = 12x
Subtract 10x from both sides.
20 = 2x
Divide both sides by 2.
10 = x
To find the measures of angles ABC and GFH, substitute 10 for x in their angle values accordingly and solve.
10x + 20
10(10) + 20
100 + 20
120
12x
12(10)
120
Answer:
x = 10; m∠ABC = 120; m∠GFH = 120
