Answer:
x=4, x=3
B is correct.
Step-by-step explanation:
Given: 
Using middle term splitting factor the left side equation.


Equate each factor to 0 and solve for x
x-4=0 or x-3=0
x=4 and x=3
Hence, The solution of the equation is 4 or 3
Answer:
dont know need points
Step-by-step explanation:
Answer:
B. x = 4 and x = -10
Step-by-step explanation:
First, expand the equation
(x + 3)² = 49
(x + 3)(x + 3) = 49
x² + 6x + 9 = 49
Subtract 49 from both sides
x² + 6x -40 = 0
Factor
(x + 10)(x - 4) = 0
Solve
x + 10 = 0
x = -10
x - 4 = 0
x = 4
So, the correct answer is B. x = 4 and x = -10
You can use greatest common factor(gcf)
list the factors of 18 and 30.
18- 1, 2, 3, 6, 9, 18
30- 1, 2, 3, 5, 6, 10, 15, 30
now the factor that is greatest is 6.
this mean you can use the largest square tile of 6in by 6in without overlap or cutting.
Answer:
Option (3)
Step-by-step explanation:
Perimeter of a regular hexagon = 30 units
Length of one side = 
= 5 units
Interior angle of hexagon = 
= 
= 120°
BC is an bisector of the angle measuring 120°.
m∠ABC = 60°
Similarly, m∠BCA ≅ ∠CAB ≅ 60°
Therefore, ΔABC is an equilateral triangle.
By the property of equilateral triangle, all sides of the triangle will be equal in measure.
AB ≅ BC ≅ AC ≅ 5 units
Perimeter of triangle ABC = AB + BC + AC
= 5 + 5 + 5
= 15 units
Option (3) will be the answer.
