Answer:
B. 
Step-by-step explanation:
Let l represent length of rectangle and w represent width of rectangle.
We have been given four formulas for the perimeter of rectangle. We are asked to choose the formula that displays a common student error for finding the perimeter.
We know that perimeter of a polygon is sum of all sides of the polygon. We also know that rectangle is polygon having two sets of equal sides.
The perimeter, P, of rectangle will be sum of its all sides that is:
Combine like terms:
Factor out 2:
Upon looking at our given choices, we can see that formula represented by option B displays a common student error for finding the perimeter.
Answer:
6x² + 5x - 6
Step-by-step explanation:
Given
(2x + 3)(3x - 2)
Each term in the second factor is multiplied by each term in the first factor, that is
2x(3x - 2) + 3(3x - 2) ← distribute both parenthesis
= 6x² - 4x + 9x - 6 ← collect like terms
= 6x² + 5x - 6
A. ∠ACE ≅ ∠ACE
This is correct.
Answer: If we look at the general definition - tan x=OAwe see that there are three variables: the measure of the angle x, and the lengths of the two sides (Opposite and Adjacent).So if we have any two of them, we can find the third. In the figure above, click 'reset'. Imagine we didn't know the length of the side BC.We know that the tangent of A (60°) is the opposite side (26) divided by the adjacent side AB - the one we are trying to find. tan 60°=BC15From our calculator we find that tan 60° is 1.733...
