Step-by-step explanation:
Answer:
its 2 (x + 5)
Step-by-step explanation:
Because it says twice the number and 5 so that would mean the 5 and x will be in brackets and twice means multiplying
Answer:
x=4
Step-by-step explanation:
-5(4-x)=-5x+20
We simplify the equation to the form, which is simple to understand
-5(4-x)=-5x+20
Reorder the terms in parentheses
+(-20+5x)=-5x+20
Remove unnecessary parentheses
-20+5x=-5x+20
We move all terms containing x to the left and all other terms to the right.
+5x+5x=+20+20
We simplify left and right side of the equation.
+10x=+40
We divide both sides of the equation by 10 to get x.
x=4
Answer:
x = -2
Step-by-step explanation:
In order to find the axis of symmetry, we will have to find the x-value of the vertex.
Vertex = (-b/2a, f(-b/2a))
In x² + 4x + 6,
a = 1 , b = 4 , c = 6
Vertex = (-4/2,f(-4/2))
Vertex = (-2,f(-2))
We have found the x-value of the vertex which is -2.
Hence, line/axis of symmetry is x = -2
