Answer:
d. 18a² - 12a
Step-by-step explanation:
f(x) = 2x² + 4x
f(-3a) = 2(-3a)² + 4(-3a)
2(-3a)² + 4(-3a)
2(9a²) + (-12a)
18a² - 12a
Answer:
no of movies (m), by Tim = 13
Step-by-step explanation:
Julie payment = constant 70 + 4.25 per additional movie = 70 + 4.25 m
Tim payment = constant 49.5 + 5.5 per additional movie = 49.5 + 5.5 m
Julie order = 12 movies. So, final payment = 70 + 4.25 (12) = 70 + 51 = 121
Equalising Tim's equation, for finding Tim's movies for same final amount , 121 = 49.5 + 5.5 m → 5.5m = 121 - 49.5 = 71.5 → m = 71.5 / 5.5 = 13
Answer:
hi
Step-by-step explanation:
The answers are:
a = cc = db + d =180 degreesHere's how:
When a line intersects two parallel lines, then corresponding angles are formed which means the same corners are congruent.
option c = d is considered.
And, because of vertical angles,
a = d is also an answer.
