First positive number (x) = x
Second positive number (y) = x+3
Product: 180 = x · y
180 = x · (x + 3)
180 = x² + 3x
0 = x² + 3x - 180
0 = (x + 15)(x - 12)
0 = x + 15, 0 = x - 12
x = -15, x = 12
x = -15 is NOT a positive number so it can be disregarded.
Answer: 12
Answer:
a+b=b+a
Step-by-step explanation:
so 7+4=12 and 4+7=12 so addition is commutative
Answer:
infinitely many solutions
Step-by-step explanation:
3x - 2x + 4 = 2 + x + 2
x + 4 = x + 4
x = x
x = x is a true statement for every value of x, so there is an infinite number of solutions.
Answer: infinitely many solutions
Answer: 517
Step-by-step explanation:
Answer:
they are both true
Step-by-step explanation:
they are both true because of proportionalities
5/8
5x2=10
8x2=16
therefore 5/8=10/16
the second one is also true because they want you to multiply y by 2
4x2=8
therefore
5/8=5/4x2
