Answer:
A. The solutions are .
B. The factored form of the quadratic expression
Step-by-step explanation:
A. To find the solutions to the quadratic equation you must:
The solutions are:
B. Two expressions are equivalent to each other if they represent the same value no matter which values we choose for the variables.
To factor :
First, multiply the constant in the polynomial by where is equal to -1.
Since both terms are perfect squares, factor using the difference of squares formula
To answer this item, we let x be the measure of angle Y. If we say supplement, it is understood that when we sum up the measures of the two angles (angle Y and its supplement) the answer should be 180. Therefore the other angle is 180-x. Going back to the condition given in this item, we will be able to generate an equation,
x = 3(180 - x)
The value of x from the equation is 135. Thus, m∠Y is 135°.
Answer:
The median is -8°F
Step-by-step explanation:
Attached Table.
The median is the "middle" value from all the numbers arranged from least to greatest.
Looking at the table, we need to arrange the numbers (first week numbers) from least to greatest.
-31, -29, -9, -8, 3, 4, 6
There are 7 numbers and the middle number is the 4th one, which is -8
The median is -8°F
