6. 4
Step-by-step explanation:
5. x =√[3×(3+5] = √3×8 =√24=2√6
6. x(x+5)=6²
x²+5x=36
x²+5x-36=0
(x+9)(x-4) =0
x=-9 or x=4
The eighth multiple of 8 is 64 .
The fifth multiple of 8 is 40 .
Their difference is 24 .
Let x is the <span>unknown number
</span><span>quotient of an unknown number and 12 : x/12
</span><span>49 more than the quotient of an unknown number and 12 : x/12 + 49
so equation:
</span>x/12 + 49 = 53
