It would either be C or D I think.
Answer:
7
Step-by-step explanation:
ab - cd = ?
Put the numbers into the correct variables of the equation.
(5)(3) - (4)(2) = ?
Now multiply 5 and 3 with each other. This leaves you with:
15 - (4)(2) = ?
Now, multiply 4 and 2 with each other. This leaves you with:
15 - 8 = ?
Now, you are able to solve the equation.
15 - 8 = 7
Answer:
y = - 2(x - 1)² + 18
Step-by-step explanation:
- 2x² + 4x + 16 ← factor out - 2 from the first 2 terms
= - 2(x² - 2x) + 16
using the method of completing the square
add/subtract ( half the coefficient of the x- term)² to x² - 2x
= - 2(x² + 2(- 1)x + 1 - 1) + 16
= - 2(x - 1)² + 2 + 16
= - 2(x - 1)² + 18 ← in vertex form
Answer:
Step 4
Step-by-step explanation:
because 100/20=5
so 60/5=12
