Find the square: (5x - 4y)2 <br><br> (and please put the process of solving the equation)
satela [25.4K]
(5x-4y)^2
(5x-4y)(5x-4y)

Multiply each term in one bracket in turn by the terms in the other bracket

(5x)(5x) = 25x^2
(5x)(-4y)=-20xy
(-4y)(5x)=-20xy
(-4y)(-4y)=16y^2

Put them together we have
25x^2-20xy-20xy-16y^2
25x^2-40xy-16y^2

A certain kind of bacteria multiplies at a rate of 150 percent per hour. When a person’s blood has 45,000,000 of these bacteria,
DIA [1.3K]
Initial number of Bacteria = Ao = 100
Number of Bacteria which make the person ill = A = 45,000,000

Growth rate = r = 150% = 1.50 

The equation model for this situation is:

A= A_{o}(1+r)^{t}

Using the values in above equation, we can write:

45000000=100(1+1.5)^{t}  \\  \\ &#10;450000=(2.5)^{t} \\  \\ &#10;log(450000)=log((2.5)^{t})  \\  \\ &#10;log(450000)=t*log(2.5) \\  \\ &#10;t= \frac{log(450000)}{log(2.5)} \\  \\ &#10;t=14.21

This means, the person will fall sick after about 14 hours.

Two numbers have theses properties . both numbers are greater than 6 . their hcf = 6 . their lcm = 60. what are the two numbers
aleksandrvk [35]
Let the numbers be x and y.
x*y=HCF*LCM=6*60=360
thus
y=360/x
next we find the list of combinations of x and y and test if they satisfy the conditions above:
(6,60),(12,30),(18,20),(24,15)
out of the above, only (6,60) and (12,30) satisfy both conditions. Thus our answer is:
(6,60) or (12,30)
