Answer:
-27/5
Step-by-step explanation:
[x*4 + 3(x-1)]\12=2+x
4x+ 3x -3 =12(2+x)
7x -3 =24 +12x
7x-12x =24 +3
-5x =27
x = (-27/5)
I don’t have a pen and paper so I can’t do this. But I can tell you what to do. Use Pythagoras’ Theorem to work it out.
a2 + b2 = c2
The c2 is the hypotenuse squared and the a2 is the other measurement so
(2 x 2) + (b x b) = 100
4 + (b2)= 100
b2 = 96
b = 9.78
Answer = 9.78
