Standard form means, move the variables to the left-hand-side and leave the constant all by herself on the right-hand-side, usually sorting the variables, so"x" goes first.
now, there's a denominator, we can do away with it, by simply multiplying both sides by the denominator, so let's do so,
Answer:
Step-by-step explanation:
tanA = sinA/cosA = (4/7)/(3/7) = 4/3
First combine like terms ,
5/5x=9/5x
move the variable which will cancel out because it is the same
5=9 is no solution sorry if i’m wrong lol
Answer:
A = 100 
Step-by-step explanation:
You have to use the area of a trapezoid formula:
A =
(a + b)
Now, substitute the values of the height and the bases:
A =
(10 + 15)
Finally, simplify the equation to solve for the area:
A = 4(25)
A = 100
