Answer:
3b
Step-by-step explanation:
if each brick is 3 inches tall, and there are b bricks, each b is 3, therefore 3b
4 5/8
4 1/8
20 1/2
4 3/8
0.25 or 16
right 3 units down 5 units

right 3 units = (3,0)
down 5 units = (0,-5)
vertex = (h,k) therefore.

Then convert the vertex form into standard form for the equation in the choice.

Thus, the answer is B.
B. 18.37
1990 - 1960 = 30 = t
Plug in the variable "t" to the equation and solve.
P (t) = 18.37
16x² - 49
= (4x)² - 7²
Identity =》 a² - b² = (a + b) (a - b)
(4x)² - 7²
= (4x + 7) (4x - 7) [3rd option]
