10 × 0.1 × t = 200
1 × t = 200
t = 200
The values of x for which the denominator is equal to zero is +2 or -2-2
<h3 /><h3>What is equation?</h3>
An equation is a mathematical expression that contains an equals symbol. Equations often contain algebra.
Given function is: y= ![\frac{(x-1)}{x^{2} -4 }](https://tex.z-dn.net/?f=%5Cfrac%7B%28x-1%29%7D%7Bx%5E%7B2%7D%20-4%20%7D)
As, for the denominator is equal to zero. We have
x²-4=0
x²=4
x=√4
x= ± 2
Thus, by putting either x= +2 or x= -2 in denominator which will gives the denominator equals to zero.

In mathematics, an inverse operation is an operation that undoes what was done by the previous operation. The four main mathematical operations are addition, subtraction, multiplication, division. The inverse of addition is subtraction and vice versa. The inverse of multiplication is division and vice versa.

If base is x
congruent side = 2x-8
perimeter=2 congruent sides +base
2(2x-8)+x=74
4x-16+x=74
5x=58
x=11.6
length of the base is 11.6 inches
