Answer:
60 r 56
Step-by-step explanation:
Answer:
x = 3.5.
Step-by-step explanation:
This is an equilateral triangle ( as all angles = 60 degrees) so all 3 sides are of equal length.
Thus 2x - 3 = 4
2x = 7
x = 3.5.
The answer to -6(x+3)=6 is x= -4
Answer:
(x + 1)² + 4
Step-by-step explanation:
the equation of a parabola in vertex form is
y = a (x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
to obtain this form use the method of completing the square
• add/subtract (half the coefficient of the x-term)² to x² + 2x
= x² + 2(1)x + 1 - 1 + 5
= (x + 1)² + 4 ← the second option
All -1.8
In addition and subtraction the order of the numbers does not matter, so the result will always remain the same
