Answer:
B. f(x) = x² + 10x + 17
Step-by-step explanation:
Given:
f(x) = (x + 5)² - 8
Required:
Write in standard form
SOLUTION:
f(x) = (x + 5)² - 8
Expand (x + 5)²
f(x) = (x + 5)(x + 5) - 8
f(x) = x(x + 5) +5(x + 5) - 8
f(x) = x² + 5x + 5x + 25 - 8
Add like terms
f(x) = x² + 10x + 17
Symmetry means that one half of the distribution is a mirror image of the other half. For example, the normal distribution is a symmetric distribution with no skew. The tails are exactly the same
its D
The two given angles are Supplementary angles and when added together need to equal 180 degrees.
2x +5 + x-5 = 180
Simplify ( Combine like terms):
3x = 180
Divide both sides by 3:
x = 180 / 3
x = 60
