Answer:
b. x² + 8x + 12 =
1. use the factoring X (see attachment)
2. 6 x 2 = 12; 6 + 2 = 12
3. (x + 6)(x + 2) = 0
4. x = -6, -2
c. x² + 13x + 12 =
1. 12 x 1 = 12; 12 + 1 = 13
2. (x + 12)(x + 1) = 0
3. x = -12, -1
c. x² + x - 12 =
1. 4 · (-3) = -12; 4 - 3 = 1
2. (x +4)(x - 3) = 0
3. x = -4, 3
f. x² + 15x + 36 =
1. 12 x 3 = 36; 12 + 3 = 15
2. (x + 12)(x + 3) = 0
3. x = -12, -3
hope this helps :)
Answer:
A:
The perimeter of the parking lot is 302 yards.
The area of the parking lot is 5,544 yards squared.
B: Perimeter
C: Area
Step-by-step explanation:
A:
To find the perimeter of the parking lot, we add all the sides up. 2L + 2W = Perimeter.
2(63) + 2 (88) = 302
To find the area, we multiply the length by the width. 63 × 88 = 5,544.
B: We need to know the amount of chain needed to surround the parking lot. In other words, we need to line the perimeter with a chain.
C: We would be paving the entire area of the parking lot.

Answer: correct answer is B
Step-by-step explanation: I know this because for example if you run one mile it will take you less time than it would if you walked 1 mile
The slope of first line is m 1= ( 1 - 0 ) / ( - 2 - ( - 6 ) );
m = 1 / 4 ;
Because the second line is perpendicular to the first line, m2 * m1 = - 1 ;
m2 * ( 1 / 4 ) = -1;
m2 = - 4 ;
The equation of the second line is : y - 3 = ( - 4 )( x - 2 );
y - 3 = -4x + 8 ;
y = -4x + 11.
