Answer:

<h3>B. -84</h3>

Step-by-step explanation:

Taking the determinant of the matrices we will have;

= 4x(5y) - 2x(3y)

= 20xy - 6xy

= 14xy

Given x = -2 and y = 3

Determinant = 14(-2)(3)

Determinant = -28*3

Determinant = -84

Answer: 36 square units

Step-by-step explanation:

Divide the figure into 2 shapes: a rectangle and a triangle. Count the squares to find the dimensions of each figure. The rectangle has a width of 4 units and a length of 6 units. The triangle has a base of 6 units and a height of 4 units.

The formula for the area of a rectangle is length * width. The area of the rectangle is 4*6 = 24 square units.

The formula for the area of a triangle is (base * height)/2. The area of the triangle is (4*6)/2 = 24/2 = 12 square units.

Add the areas of both the rectangle and triangle. 24+12 = 36 square units.

Solve for y.<br> 2 (y-2) = 4y + 8 - 2 (-4y - 3)
Lubov Fominskaja [6]

Answer:

-1.5

Step-by-step explanation:

  • 2 (y-2) = 4y + 8 - 2 (-4y - 3)
  • 2y-4=4y+8+8y+6
  • 2y-4=12y+14
  • -4-14=14y-2y
  • -18=12y
  • y=-18/12
  • y=-1.5
