Answer:
4x^2 - 25
Step-by-step explanation:
Here you can apply the difference of two squares formula, (a+b)(a-b) = a^2 - b^2, such that:
(2x+5)(2x-5) = (2x)^2 - (5)^2
Applying the exponential rule, you receive:
(2x)^2 - (5)^2 = 2^2 * x^2 - 5^2
And simplifying, 2^2 * x^2 - 5^2 you receive:
4x^2 - 25
As simple as that!
Half of 1/5 is 1/10. one tenth plus one tenth is one fifth
We know perimeter is the amount of units around a figure. If we want to add to a composite figure without increasing the perimeter, we must add to it by using the space on the inside of the figure. For example, if we have a square, we can make it a composite figure by splitting the square with a diagonal line. This adds to the figure without adding to its perimeter.
