We can calculate the width of the rectangle patio with pythagorean theorem:
![\begin{gathered} \text{Base of triangle=15-12=3} \\ c^2=a^2+b^2 \\ 5^2=3^2+b^2 \\ b=\sqrt[]{25-9} \\ b=\sqrt[]{16} \\ b=4 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20%5Ctext%7BBase%20of%20triangle%3D15-12%3D3%7D%20%5C%5C%20c%5E2%3Da%5E2%2Bb%5E2%20%5C%5C%205%5E2%3D3%5E2%2Bb%5E2%20%5C%5C%20b%3D%5Csqrt%5B%5D%7B25-9%7D%20%5C%5C%20b%3D%5Csqrt%5B%5D%7B16%7D%20%5C%5C%20b%3D4%20%5Cend%7Bgathered%7D)
Then, she need to put trim on the edge of the floow of the patio that is wood planks and DOES NOT share and edge with the brick part:
Loretta need to put 28 feet of trim.

Answer: second one, then the 4th one
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Here the vertex = (- 2, - 3 ) , then
y = a(x - (- 2))² - 3 , that is
y = a(x + 2)² - 3
To find a, substitute any point on the graph into the equation
Using the coordinates of the y- intercept (0, 5 )
5 = a(0 + 2)² - 3 ( add 3 to both sides )
8 = a(2)² = 4a ( divide both sides by 4 )
2 = a
y = 2(x + 2)² - 3 → B
Answer:
B
Step-by-step explanation:
It cannot be D, because it costs way more, it cannot be C because there are other options that provide better value. We can finally determine that it is B because for 3 pens more it is only 9 cents more
