Answer:
P = 26x -4
Step-by-step explanation:
The perimeter is found by
P = 2(l+w)
P = 2( 5x+7 + 8x-9)
Combine like terms
P = 2( 13x -2)
Distribute
P = 26x -4
<u>Answer</u>:
Distance of bottom of the ladder from the base of the building is 5.18 feet.
Step-by-step explanation:
Given:
Length of ladder = 20 feet
Angle formed between ladder and ground = 75 degrees.
To Find:
Distance of bottom of the ladder from the base of the building.
Solution:
Consider the below figure forming a triangle ABC.
AB is building
AC is ladder , so AC = 20 feet
BC is distance between base of building and bottom of ladder.
And angle between ground and ladder that is ∠C = 75degrees
Need to calculate BC ,
As triangle ABC forms right angled triangle , right angle at B ,
So
=> BC = AC cos C
=> BC= 20 cos (75)
=> BC = 5.18 feet
Hence distance of bottom of the ladder from the base of the building is 5.18 feet.
Answer:
$7.28
Step-by-step explanation:
The average price, or the expected price, of any item in this specialty store is given by the weighted average of each item's price. That is, the sum of the products of each individual price by its corresponding sales mix:
The average price of any item in the store is $7.28
You first have to distribute the negative to the second pair of parenthesis. So the new equation would be 2n-4-4n+3. Next you combine like terms. So your final answer is -2n-1.
