Let this number be represented by the variable "n"
product of 4 and n is multiplying4 and n
4 * n = 5.6
divide 4 to both sides to isolate the variable on one side
n=1.4
Tell him to stop buying shoes, you wouldnt have this questions.
that would be 1/2 :P
Answer:
x = -3 +/- square root(22)
Step-by-step explanation:
x = -b +/- square root(b^2 - 4ac) / 2a
ax^2 + bx + c = 0
these are both the quadratic formula but one is solved for the x and another for 0
a= 1
b= 6
c = -13
x= -6 +/- square root( 6^2 - 4(1)(13)) / 2(1)
x = -6 +/- sqrt( 36 + 52) / 2
x= -6 +/- sqrt (88) / 2
sqrt of 88 = 2 x sqrt (22)
divide 2 on each
x= -3 +/- sqrt (22)
Divide 2 from both sides
t < 5/2
Hope this helps!
