Answer- (5x-1)(2x+1)
let me know if you need to see work
The formula for the area of a triangle of base b and altitude h is A = (1/2)(b)(h).
Here, b = 18 cm and h = 9 cm. Thus, the desired area is:
(18 cm)(9 cm)
A = ----------------------- = 81 cm^2
2
This problem gives you more info than is needed to solve it. The area of the given triangle is 81 cm^2.
Answer:
The concept or process is
.
Step-by-step explanation:
Consider the provided information.
The following property can be used to rewrite each radical as an exponent.
The numerator tells the power of the resulting rational exponent, and the denominator of the rational exponents tells the root of that number.
![x^{\frac{m}{n}}=(\sqrt[n]{x})^m](https://tex.z-dn.net/?f=x%5E%7B%5Cfrac%7Bm%7D%7Bn%7D%7D%3D%28%5Csqrt%5Bn%5D%7Bx%7D%29%5Em)
For example:
![(27)^{\frac{2}{3}}=(\sqrt[3]{27})^2](https://tex.z-dn.net/?f=%2827%29%5E%7B%5Cfrac%7B2%7D%7B3%7D%7D%3D%28%5Csqrt%5B3%5D%7B27%7D%29%5E2)


Hence, the concept or process is
.
