Start from 7, then add 5 each time.
a7 is 7 plus 30, or 37.
JH = 3x-3
21. x = ?
can someone help asap please!!!
Answer:
Step-by-step explanation:
and is half of the whole measurement of . So, to find the value of , you need to write an expression by using those measurements of both and . Then, solve for :
-Solve:
So, the value of is .
x = 4 and x = –4
x = 8 and x = –8
x = 16 and x = –16
The correct statement is that the solution of this equation x² – 16 = 0, is 4 and -4.
It is a polynomial that is equal to zero. Polynomial of variable power 2, 1, and 0 terms are there. Any equation having one term in which the power of the variable is a maximum of 2 then it is called a quadratic equation. The general form of the quadratic equation is ax² + bx + c = 0
Given
The quadratic equation x² – 16 = 0
To find
The root of the quadratic equtaion?
The quadratic equation x² – 16 = 0
We know the formula,
a² - b² = ( a - b ) ( a + b )
Then
x² – 4² = 0
(x - 4)(x + 4) = 0
x = 4 and -4
Thus, the solution of this equation x² – 16 = 0, is 4 and -4.
More about the quadratic equation link is given below.
Answer: The correct option is (B) x = 4 and x = -4.
Step-by-step explanation: We are given to find the solutions to the following quadratic equation :
Since the coefficient of x is zero in the given equation, so we will be using the method of square root to solve the equation.
From equation (i), we have
Thus, the required solution is x = 4 and x = -4.
Option (B) is correct.
Answer:
A vertex on polygon ABCD and its corresponding vertex on polygon AGHBGHCGHDGH are always equidistant from the line of reflection. Each of the four line segments (, for example) is perpendicular to and cut in half by the line of reflection, . This means that is a perpendicular bisector of those line segments.
