Answer: 
Step-by-step explanation:
For this exercise you can use the following formula for calculate the slope:
In this case you know that the given line passes through the points (-3,0) and (1.4). Therefore you can identify that:
Then, in order to calculate the slope of this line, you must substitute the coordinates of the points into the formula:
Finally, evaluating, you get that the slope of this line is the following:
Answer:30
Step-by-step explanation: act like both of the triangles are there, that is a rectangle 6 times 10 equals 60. 60 divided by 2 is 30
Answer:
23.4
Step-by-step explanation:
you use the equation for pythagorean theorem which is a^2+b^2=c^2 and plug in 12 and 18 into the a and b values to get 15^2+18^2=c^2 then you find the numbers squared so 225+324=c^2 add. 549=c^2 find square root. 23.4 rounded.
In order to maintain the similarity, both x and y has to be amplified by the same ratio
So A will be correct
