The equation for finding the area of a triangle is (bh)/2.
(The slash is a division sign)
So, with this equation, it would be (19*12)/2.
That would equal 114. So the answer is 114 ft squared.
It’s false because if you take a negative number away from another negative number it would give you another negative number not a positive number!
Answer:
1) 
2) 





Step-by-step explanation:
The Pythagorean Theorem is:

Where a is the hypotenuse and b and c are the legs.
The missing side lenght is one of the legs, then you must solve for one of them. Therefore, this is:

MEASURE OF ANGLE:
Keep the identities on mind:



Susbstitute values, then:






Answer:
f'(a) = -4
Step-by-step explanation:
f(x) = 3 − 4x
Take the derivative of the function
f'(x) = -4
f'(a) = -4
About 36000 because if u multiply 3000 the price of the automobile by number of payments 12 you get 36000
