The answer is 28. 7x2=14 and then 14x2=28. Remember PEMDAS
The second one is correct. 66/300 = x/100
Answer:
vertex = (4, - 8 )
Step-by-step explanation:
The equation of a quadratic in vertex form is
f(x) = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
f(x) = (x - 4)² - 8 ← is in vertex form
with (h, k ) = (4, - 8 ) ← coordinates of vertex
Answer:
A
Step-by-step explanation:
since 36=6² and the other option is not square of integer
Answer:
x =2, x = 4
Step-by-step explanation:
x^2 - 6x + 8 = 0
(x - 2)(x - 4) = 0
x - 2 = 0; x = 2
x - 4 = 0; x = 4
