Answer:
The term 2lw is independent of the height
Step-by-step explanation:
This formula is usually obtained reasoning like this: the rectangular prism has 6 faces, thus the surface area is the sum of the areas of these faces.
2 faces are l×w rectangles, so their area is lw+lw=2lw. Note that we are not using the height to compute the area, then this is the independent term.
The 4 remaining rectangles involve the height as one of their dimensions, so their areas (2hw+2lh) depend on the height.
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
If you take your calculator and enter in -82+28 it should give you the answer easily If you dont have one use ur phone.
