First you have to simply distribute the + through the parentheses
16+f+4
Then you combine like terms (in this case the 16 and the 4)
f+20
16+(f+4) simplified is f+20
Hope this helps!!
This is simple mathematics. 37 - 25 = 12
She travelled 12 feet beneath sea level.
32 because all u need to do is add thirty two plus 15 and you’ll get thirty two
Answer: First Option
,
Step-by-step explanation:
We know that the sine function is defined as:
In the same way the cosine function is defined as:
Therefore it is fulfilled that:
Opposite: is the length of the side opposite angle
Adjacent: It is the length of the side that contains the angle of 90 ° and angle A
Hypotenuse: It is the length of the side opposite the angle of 90 °
So:
A = (3,2)
B = (7,5)
The difference between x coordinates is 7-3 = 4, which squares to 4^2 = 16
The difference in y coordinates is 5-2 = 3 which squares to 3^2 = 9
add up the squares: 16+9 = 25
Then take the square root: sqrt(25) = 5
So the distance from A to B is 5 units
The length of segment AB is 5 units
The scale factor of 3 tells us to lengthen the segment by a factor of 3. In other words, triple the length
new length = (scale factor)*(old length)
new length = (3)*(5)
new length = 15
Answer: 15
