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
You can set this up as 5(3+4)....then, distribute by multiplying the terms in parentheses by 5. This gives you 15+20, which equals 35.
Answer:
1/2
2 is the total parts. you can visualise it as a circle or another form of a diagram. so theres 2 parts. 1 might mean one segmented is shaded or cut depending on the context
Step-by-step explanation:
In ∆ABC, m∠B = 90°
Therefore ∆ABC is a right angled triangle with sides AB = 4 & BC = 3. AC is the hypotenuse.
Hence, by Pythagoras theorem:
