Answer:
n = -5/13
Step-by-step explanation:
-8+4(1+5n)=-6n-14 (from PEDMAS, expand parenthesis first)
-8+1(4) +5n(4)=-6n-14
-8+4 +20n=-6n-14
-4 + 20n = -6n -14 (add 6n to both sides)
-4 + 20n + 6n = -14
-4 + 26n = -14 (add 4 to both sides)
26n = -14 + 4
26n = -10 (divide both sides by 26)
n = -10/26 = -5/13
Answer:
6root2 × 6root2
you have to use pythagoras
a²+b²=c²
c=12
12²=144
a²+b²=144
but it is a square so I'll just change a and b to x because it shows they are equal
x²+x²=144
2x²=144
x²=72
x=6root2
