Base is 12 feet square so 12 *12 = 144 square feet
each triangle has base of 12 feet and height of 8 feet
area of triangle = 1/2 x base x height = 1/2 x 12 x 8 = 48 square feet
48 x 4 triangles = 192 square feet
total: 192 + 144 = 336 square feet
Answer:
irrational
are the numbers like 7.55782902..where the numbers aren't repeated
Answer: Choice #2
Step-by-step explanation: The slope of -1/4 means that the line is ascending to the left, which rules out the first and last choice. The y-intercept of -3 means that it crosses the y-axis at (0,-3). This is why it is #2.

i read in class 4 but I don't explain the answer
X-intercepts
f(x) = 0
4x² - 15x - 4 = 0
4x² - 16x + x - 4 = 0
4x(x - 4) + 1(x - 4) = 0
(x - 4)(4x + 1) = 0 ⇔ x - 4 = 0 or 4x + 1 = 0
x = 4 or 4x = - 1 ⇒ x = - 1/4
Answer: -1/4 and 4.
