Answer:
11x + 12
Step-by-step explanation:
9x + 3x = 11x
8 + 4 = 12
Answer:
32 blocks
Step-by-step explanation:
distance between home (0,0) and mall (0,7) = 7
distance between mall (0,7) and movies (9,7) = 9
distance between movies (9,7) and store (9,0) = 7
distance between store (9,0) and home (0,0) = 9
7 + 9 + 7 + 9 = 32 blocks
M-30=10
It could also be 30-m=10
The answer for the first one would be 10+30=m
m=40
The answer for the second one would be 30-10=m
m=20
Hope this helps :)

Answer:
see explanation
Step-by-step explanation:
The vertex form of f(x) is
f(x) = (x - h)² + k
where (h, k) are the coordinates of the vertex
To obtain this form use the method of completing the square
add/subtract ( half the coefficient of the x- term )² to x² + 14x
f(x) = x² + 2(7)x + 49 - 49 + 36
= (x + 7)² - 13
The minimum value of f(x) is the y- coordinate of the vertex
vertex = (- 7, - 13), that is minimum value = - 13
