Answer:

Infinite solutions

Step-by-step explanation:

Substitute -2x - 5 for y in 6x + 3y = -15

$6x + 3 (-2x-5)=-15$
$6x + (3)(-2x)+(3)(-5) = -15$ (simplify both sides of the equation
$6x -6x-15 =-15$
$-15 = -15$
$-15 + 15 = -15 + 15$ (add 15 to both sides)
$0 = 0$

Therefore, the answer is infinite solutions.

Answer: 840 square inches

1. Split the figure into two rectangles.

2. Find x (there are other missing sides, but you do not need to know them).
x = 40 - 10
x = 30

3. Find the area of the two rectangles. Remember: A = lw.
Top rectangle: (10)(30) = 300
Bottom rectangle: (18)(30) = 540

4. Add the rectangles' areas together.
300 + 540 = 840
