5)
Equilateral triangle, all sides are equal
So 2x + 5 = 11
2x = 6
x = 3
Answer is the first one
3; Equilateral theorem
6)
Isosceles triangle has at least two congruent sides.
So 6x = 24
x = 4
Answer x = 4
Converse of the Base Angle Theorem
7)
5x + 7 = 52
5x = 45
x = 9
Answer
x = 9
Base angle theorem
8)
5y - 14 = 3y
2y = 14
y = 7
Answer
7; Equiangular theorem
Lines cannot intersect at multiple points...so the answer would have to be C :)

Answer:
x = - 2
Step-by-step explanation:
f(x) + g(x) = x² - 2x + 6x + 4 = x² + 4x + 4, hence
x² + 4x + 4 = 0 ← This is a perfect square in the form
(x + a)² = x² + 2ax + a²
Hence 2a = 4 ⇒ a = 2, thus
(x + 2)² = 0
x+ 2 = 0 ⇒ x = - 2 ( 2 equal roots )
Value of x = - 2
