Let's solve ~




It's factorized now ~ And if you want to find the zeros then equate the expression with 0.
And you will get ;

1 foot is 12 inches. So just divide 81 by 12.
81/12 = 6.75
So your answer is 6.75 feet.
Answer:
is this a joke question? it is very easy. one half or 1/2
Step-by-step explanation:
4. all for angles need to equal 360
90 +90 + 42 = 222
360-222 = 138
y = 138 degrees
x - 42 degrees
6. x = arctan(8/4) = 63.43 degrees ( round as needed)
y = 16 / tan(63) = 8.15 ( round as needed)
A number exressed using exponents is a power.
