Answer:
A
Step-by-step explanation:
Given
x² + 6x + 4 = 0 ( subtract 4 from both sides )
x² + 6x = - 4
Solve using the method of completing the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(3)x + 9 = - 4 + 9, that is
(x + 3)² = 5 ( take the square root of both sides )
x + 3 = ± 
( subtract 3 from both sides )
x = - 3 ± , thus
x = - 3 - → A
x = - 3 +
Equating "equal" as symmetrical:
Two windows of the same size and placed in the same position is considered symmetrical. In an example where one window is placed at a certain distance from a wall and a certain distance from the floor, another window of the same size is also placed in the opposite side of the first window (based on a constant center) with the same distance from the floor and wall. The two windows can be considered equal.
Answer:
9
Step-by-step explanation:
Distance between two points is given as;
Square root [(X2-x1) 2+ (y2-y1)2]
= (6-(-3))2 +(-4-(-4))2
=Square root (81 +0)
=9
Answer:
10 scholars
Step-by-step explanation:
you just to count all of the ones taller than 36 and the subtracrt by all the ones shorter than 36.
scholars = 13 - 3 = 10
