Answer:
15 units
Step-by-step explanation:
By using the Pythagoras Theorem,
C^2 = A^2 + B^2
Substitute in the given values,
25^2 = a^2 + 20^2
625 = a^2 + 400
625 - 400 = a^2 + 400 - 400
a^2 = 225
= 15
Hope this too helped! ^^
I'd recommend watching a video or two on the topic of Pythagoras Theorem, if this explanation isn't clear enough.
Answer:
4*10^-6
Step-by-step explanation:
Since any off integer is in the form (2x+1) then three consecutive integers who's sum is 183 will be in the form (2x+1)+(2x+3)+(2x+5)=183
6x+9=183
subtracting 9
6x=174
dividing by 2
3x=87
dividing by 3
x=29
so the integers are
2(29)+1=59
2(29)+3=61
2(29)+5=63
to check our answer let us sum up the integers
59+61+63=59+1+60+63=60+60+63=183
Answer:
C
Step-by-step explanation:
Answer:
Substitution, but this system of equations has no solution.
Step-by-step explanation:
2x-4y=10
2y+6=x
----------------
2(2y+6)-4y=10
4y+12-4y=10
12=10
no solution.
