Answer:
X = 2 / Z = 78
Explanation:
We are given 102 degrees, and the formula across from it, the one with the x, equals the same degrees. Knowing that we have to get them to equal each other, subtract 102-86, and you'll get 16. Next, divide 16 by the given number, 8, and you'll get x = 2
Knowing a straight line equals 180 degrees, subtract 180-102, and you'll get z, which is 78
7, to find the mean add up all the numbers and then subtract by the amount of Humber a you added.
For example, 1,3,8,10 added together is 22. We added four numbers together, so divide by 4. The mean of 1,3,8,10 is 5.5
1. It is a quadratic equation.
Explanation:
A quadratic equation is any equation that can be rearranged in standard form (ax^2 + bx + c). That equation can be rewritten as -x^2 + 1, where a is -1, b is 0, and c is 1.
2. 4x^2, 3x, and 5.
Explanation:
A quadratic term is ax^2 in the formula ax^2 + bx + c. A linear term is bx in the formula, and a constant is c in the formula.
