Silvio wants to find the perimeter of quadrilateral ABCD. He begins by computing the length of side AB using the distance formula. Finish Silvio’s work to find the length of side AB.What is the perimeter of quadrilateral ABCD?
15 units
17 units
18 units
20 units
Answers
AB = √ 16 + 9
AB = √ 25
AB = 5
AD = 4 ; DC = 4 ; BC = 7
Perimeter = 5 + 4 + 4 + 7 = 20 units
Answer: 20 units

How many real number solutions are there to the equation 0=3x^2 + x - 4?
What are the solutions of the system
Y=x + 5
Y=x^2 - x + 2
Answers
y = 3x - 1
2x² - 3 = 3x - 1
+ 1 + 1
2x² - 2 = 3x
2x² - 3x - 2 = 0
2x² - 4x + x - 2 = 0
2x(x) - 2x(2) + 1(x) - 1(2) = 0
2x(x - 2) + 1(x - 2) = 0
(2x + 1)(x - 2) = 0
2x + 1 = 0 or x - 2 = 0
- 1 - 1 + 2 + 2
2x = -1 or x = 2
2 2
x = -0.5
y = 3x - 1 or y = 3x - 1
y = 3(-0.5) - 1 or y = 3(2) - 1
y = -1.5 - 1 or y = 6 - 1
y = -2.5 or y = 5
(x, y) = (-0.5, -2.5) or (x, y) = (2, 5)
————————————————————————————————
3x² + x - 4 = 0
3x² - 6x + 2x - 4 = 0
3x(x) - 3x(2) + 2(x) - 2(2) = 0
3x(x - 2) + 2(x - 2) = 0
(3x + 2)(x - 2) = 0
3x + 2 = 0 or x - 2 = 0
- 2 - 2 + 2 + 2
3x = -2 or x = 2
3 3
x = ⁻²/₃
There are two real number solutions in the equation.
————————————————————————————————
y = x + 5
y = x² - x + 2
x + 5 = x² - x + 2
+ x + x
2x + 5 = x² + 2
- 2 - 2
2x + 3 = x²
0 = x² - 2x - 3
0 = x² - 3x + x - 3
0 = x(x) - x(3) + 1(x) - 1(3)
0 = x(x - 3) + 1(x - 3)
0 = (x + 1)(x - 3)
0 = x + 1 or 0 = x - 3
- 1 - 1 + 3 + 3
-1 = x or x = 3
y = x + 5 or y = x + 5
y = -1 + 5 or y = 3 + 5
y = 4 or y = 8
(x, y) = (-1, 4) or (x, y) = (3, 8)

Answer:
Its B 270 square feet
Step-by-step explanation:
The solution is 270 square feet. There are 3 feet in 1 yard, and 9 square feet in 1 square yard. Therefore, we can multiply 30 by 9 to get a total of 270 square feet.

How you find LCD (lowest common denominator) is that you have to look at the denominator (the bottom number) and try to find the lowest multiple between both of the numbers that is on the bottom (in this case it is 2 and 5). Sometimes you have to multiply both denominators together to get a LCD.
Example of multiplying two denominators together to get an LCD:
1/3 and 1/13 LCD is 39 because you multiply 3 and 13.
1/5 and 1/4 LCD is 20 because you multiply 5 and 4.
