Use the formula for the area of a triangle, and fill in the given information.
.. A = (1/2)*b*h
.. 36 in^2 = (1/2)*b*(9 in)
.. (72 in^2)/(9 in) = b . . . . . . . . multiply by 2, divide by 9 in
.. 8 in = b
The base is "none of the above", 8 inches.
_____
This question has a couple of problems:
.. 1) area is not measured in "inches"; it is measured in "square inches."
.. 2) ALL of the offered answer choices are INCORRECT.
Do parentheses first according to PEMDAS.
3 squared is 9 and add 4 to get 13
Do 52 minus 13 to get 39
Answer:
-10x^2-33x+1
Step-by-step explanation:
=>6x(x-4)-16x^2-(9x-1)
multiply 6x with (x-4) and multiply - with (9x-1).
= 6x^2-24x-16x^2-9x+1
arrange the like terms with same powers of x with the respective sign.
= 6x^2-16x^2-24x-9x+1
simplify by using the respective arthematic operations.
= -10x^2-33x+1
