No, a lone variable has an invisible one in front of it, So 4z (can’t put the top number sorry) So 4z - z would equal 3z
I don’t really know but try a calculator
A trapezoid does not have a rotational line of symmetry
ok imma try...
Answer: the corresponding sides are proportional. and they arent the same shape, please correct me if im wrong
<u>Step-by-step explanation:</u>
An equation is a mathematical statement that two things are equal. It consists of two expressions, one on each side of an 'equals' sign. If the quadratic polynomial = 0, it forms a quadratic equation. Therefore, the standard form of a quadratic equation can be written as: ax² + bx + c = 0 ; where x is an unknown variable, and a, b, c are constants with 'a' ≠ 0 (if a = 0, then it becomes a linear equation).An equation with a degree of 2 is a quadratic polynomial , which means having a maximum of degree 2 .
Given below are some examples of equation with a degree of 2 :
6x² + 11x - 35 = 0.
2x² - 4x - 2 = 0.
-4x² - 7x +12 = 0.
20x² -15x - 10 = 0.
x² -x - 3 = 0.
5x² - 2x - 9 = 0.
3x² + 4x + 2 = 0.
-x² +6x + 18 = 0
