1. (x+2)(x-2)(x+2)(x-2)
3. (16x+3)(16x-3)
x/2 - 5 =3
add 5 to each side. this is the addition property of equality
it says when we add the same thing on both sides of the equation, we are not changing the value of the equation
we are using this to get the variable on one side and the constant on the other
x/2 -5+5 = 3+5
x/2 =8
multiply each side of the equation by 2
we are using the multiplication property of equality
it says when we multiply each side of the equation by the same thing, we are not changing the value of the equation
x/2 *2 = 8*2
x = 16
2.5*d+5= 65
subtract 65 by 5 and divide by 2.5 to get the number of days shes had the plant :)
The equation for compound interest is:
Where r is the interest rate and n is the number of times per year it's applied.
Annually n = 1 and 7% interest r = 0.07
The quarterly rate 2% is already quartered 0.02 = r/n .
You can see that Alexander is incorrect. A quarterly compound interest rate of 2% will accrue more interest than a 7% compound annual interest rate.
1.7% compound quarterly
Well, to get the surface area, you do length x width x height. <span>Multiply the side length of the base by the slant height and divide by two. Then, multiply by 4. This will give you the lateral </span>surface area<span> of the </span>pyramid<span>.</span>
