The last one
You’re completing the square here so you have to find (1/2b)^2. In this case it’s 1. So you have to add 1 to both sides. Then you have to solve for it
It becomes
(x-1)^2 = -7
Then you have to find the square root
(x-1) = √-7
x-1 = √7 √-1
x-1= ± i √7
x= 1 ±i √7
That’s your answer and d is the only one that matches with it
A) x -y = 4
B) x + y = 30
x = 4 + y So,
B) 4 + y + y =30
2 y = 26
y = 13
x = 17
Answer:
4x2−24x4x2-24x
Factor 4x4x out of 4x24x2.
4x(x)−24x4x(x)-24x
Factor 4x4x out of −24x-24x.
4x(x)+4x(−6)4x(x)+4x(-6)
Factor 4x4x out of 4x(x)+4x(−6)4x(x)+4x(-6).
4x(x−6)4x(x-6)
4x2−24x4x2-24x

Your question was:
A triangle with an angle of 74, 6z, z+36 degree
=> apply rule: sum of the interrior angle of a triangle is 180
180 = 6z+74+z+36
=> solve for z
z= 10
Therefore, the other angles are
10+36=46 degree
6*10=60 degree
and
z = 10 degree
