Step-by-step explanation:
To solve the expression, we must know about an expression.
<h2>Expression</h2>
In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations that are formed according to rules which are dependent on the context.
The solution of the expression is 2a.
<h3>Given to us</h3>
![\dfrac{4a+4}{2a}\times \dfrac{a^2}{a+1}\\\\](https://tex.z-dn.net/?f=%5Cdfrac%7B4a%2B4%7D%7B2a%7D%5Ctimes%20%5Cdfrac%7Ba%5E2%7D%7Ba%2B1%7D%5C%5C%5C%5C)
<h2>Solution</h2>
![\dfrac{4a+4}{2a}\times \dfrac{a^2}{a+1}\\\\](https://tex.z-dn.net/?f=%5Cdfrac%7B4a%2B4%7D%7B2a%7D%5Ctimes%20%5Cdfrac%7Ba%5E2%7D%7Ba%2B1%7D%5C%5C%5C%5C)
Multiplying both we get,
![=\dfrac{(4a+4)\times a^2}{2a \times (a+1)}\\\\](https://tex.z-dn.net/?f=%3D%5Cdfrac%7B%284a%2B4%29%5Ctimes%20a%5E2%7D%7B2a%20%5Ctimes%20%28a%2B1%29%7D%5C%5C%5C%5C)
Taking 4 as common from the numerator,
![=\dfrac{4(a+1)\times a^2}{2a(a+1)}\\\\](https://tex.z-dn.net/?f=%3D%5Cdfrac%7B4%28a%2B1%29%5Ctimes%20a%5E2%7D%7B2a%28a%2B1%29%7D%5C%5C%5C%5C)
Canceling (a+1) from both numerator and denominator,
![=\dfrac{4a^2}{2a}\\\\](https://tex.z-dn.net/?f=%3D%5Cdfrac%7B4a%5E2%7D%7B2a%7D%5C%5C%5C%5C)
Expanding further,
![=\dfrac{2\times 2 \times a \times a}{2 \times a}\\\\](https://tex.z-dn.net/?f=%3D%5Cdfrac%7B2%5Ctimes%202%20%5Ctimes%20a%20%5Ctimes%20a%7D%7B2%20%5Ctimes%20a%7D%5C%5C%5C%5C)
Canceling 2 and a,
= 2a
Hence, the solution of the expression is 2a.

Answer:
35
Step-by-step explanation:
Lisa will have 35 strips since 14÷0.4=35
Use the Pythagorean Theorem, substituting 8, 15, and 17 for a, b, and c respectively. Then, simplify to determine whether the equation is true.
![8^2+15^2=17^2](https://tex.z-dn.net/?f=8%5E2%2B15%5E2%3D17%5E2)
![64+225=289](https://tex.z-dn.net/?f=64%2B225%3D289)
![289=289](https://tex.z-dn.net/?f=289%3D289)
As any number is clearly equal to itself, this statement is true, so 8, 15, and 17 is a valid Pythagorean Triple.
