Answer:
x = 4
-4x+21 => 5
Step-by-step explanation:
The given triangle in the picture is isosceles triangle which means that two sides of the triangle are equal.
So,

Now
Putting all the values in equation for perimeter

Putting x = 4 in side 1

Hence,
x = 4
-4x+21 => 5
Is it 351,591 or is it the other wag around?
Answer:
=> Expand by applying the FOIL method

=> combine like terms

Step-by-step explanation: The first step when factoring any polynomial is to factor out the GCF. The GCF is the greatest common factor for all the terms of the polynomial. By factoring out the GCF first, the coefficients and constant term of the polynomial will be reduced.
Answer:
1
Step-by-step explanation:
i²⁵⁶ is the equivalent of (i²)¹²⁸.
(i²)¹²⁸ = (-1)¹²⁸ = 1.
