So you’d add 5 and 3 so it’s 8 ft/s
You then divide 220/8
So it should be 27.5 seconds.
Sorry about that other guy. Hope this helps!
Answer:
Part a) The measure of the sides of triangle DEF are



Part b) Is a scalene triangle
Step-by-step explanation:
we know that
the formula to calculate the distance between two points is equal to

we have the coordinates
D(8,-6) E(-1,-3) F(-2,5)
step 1
Find the length side DE
D(8,-6) E(-1,-3)
substitute in the formula



step 2
Find the length side EF
E(-1,-3) F(-2,5)
substitute in the formula



step 3
Find the length side DF
D(8,-6) F(-2,5)
substitute in the formula



step 4
Classify the triangle by the measure of its sides
we have



so
Is a scalene triangle, because is a triangle in which all three sides have different lengths.
Answer:
x = 5
y = 7
Step-by-step explanation:
<em>Since they are both equal to </em><em>y</em><em>, we can set them equal to each other.</em>
2x - 3 = x + 2
<em>Combine like terms and isolate the </em><em>x</em><em>.</em>
x = 5
<em>Plug in the x to either equation to get the value of </em><em>y</em><em>.</em>
y = (5) + 2
y = 7
