We have 2 numbers x,y
x=4y (1)
x+y=155<=> We are replacing the (1) => 4y+y=155 <=> 5y=155 <=> y=31
so we are replacing in the (1) x=4×31<=> x=124
so the two numbers? is 31 and 124
Hope this helps!
Guest "Exactly one of the axioms of a vector space is not satisfied"
Witch is this axiom?
Rom yes im sure the exercise say it's not.For this reason i can't solve the exercise
8 if you dont count the square ABCD and 9 if you count it
Oh ok np then!
I'm fine,you?(Post it like off-topic)
This question its like "we will take the 0" But 0 is not positive so no we will not take it!
Hope I help you to understand!
Yes right question because the exercise say solutions we will have 4 positive integer values of k
x=−b±√b2−4ac2a=−10±√102−4k22k If rational solutions means x real so must 102−4k2>0
So k=1,2,3,4
Total 4 positive integer values of k
It's (3x+4)(9x2−12x+16) because if you do distributive property you will have 27x3+64
