Answer:
(-2, -3)
(3, 12)
Step-by-step explanation:
To solve this, we're gonna get rid of the y's with substitution
x² + 2x - 3 = 3x + 3
Let's make this equation equal to zero
Subtract 3 from both sides
x² + 2x - 3 = 3x + 3
- 3 - 3
x² + 2x - 6 = 3x
Subtract 3x from both sides
x² + 2x - 6 = 3x
- 3x - 3x
x² - x - 6 = 0
Factor the equation
(x - 3)(x + 2) = 0
This means x can be -2 or 3
Let's solve it with -2 first, plug the new x in y = 3x + 3
y = 3(-2) + 3
y = -6 + 3 = -3
Do the same for x = 3
y = 3(3) + 3
y = 9 + 3 = 12
3 Tons = 6000 pounds
300 is 5% of 6000 so the answer is 5% :)
-3/2
Down 3
Right 2
As an improper fraction it would be -1 1/2

Answer:
<em>The perimeter of the green cross is 32 cm</em>
Step-by-step explanation:
<u>Perimeter</u>
It's the sum of all the external side lengths of a given shape.
The green cross formed by two rectangles is shown in the figure below.
We have outlined the dimensions of the external sides of the resulting cross.
Note there are four corners of 2 cm by 2 cm and four sides of 4 cm each.
The total perimeter is:
8 * 2 cm + 4 * 4 cm = 16 cm + 16 cm = 32 cm
The perimeter of the green cross is 32 cm
