Answer:
46 wpm
Step-by-step explanation:
230 words in five minutes is 230/5 words per minute
When simplifying we get 46
Answer:
-3
Step-by-step explanation:
-(-3) = 3
-(-6) = 6
-3 - (-6) = 3
-c - d
c = -3
-3 - d
d = -6
-3 - (-6)
=-3+6
=3
I don't think its possible to do this... you have to have 2 equations
Answer:
The hypotenuse of a right triangle is 4m longer than the shorter leg and 2m longer than the longer leg. What are the lengths of the sides?
Just for variety, consider the hypotenuse = h, the short leg h-4 and the long leg h-2.
c^2 = a^2 + b^2; so h^2 = (h-4)^2 + (h-2)^2; h^2 = h^2 - 8h + 16 +h^2 -4h +4;
h^2 -12h +20 = 0 factors to (h - 10)(h - 2) = 0 so h = 2 or h = 10
Since (h - 2) = (2 - 2) = 0 and a triangle cannot have a side of zero length, 10 is the length of the hypotenuse.
h^2 = (h-4)^2 + (h-2); 10^2 = (10-4)^2 + (10-2); (10)^2 = (6)^2 + (8)
The hypotenuse is 10 cm, short leg 6 cm and long leg 8 cm.
