Answer:
hypotenuse=h
h = 1 + 1,5
h= 2,5
h²= catheto²+catheto²
2,5² = 1,5² + x²
x²= 2,5² - 1,5²
x²= 6,25 - 2,25
x²=4
now you have to do the square root of 4 which is 2 (2×2 = 4)
x= 2
Answer: 1 gallon
Step-by-step explanation:
Hi there!
Using the equation (12*18)-(7*3), where 12*18 is the area of the wall, 7*3 is the area of the door not being painted, you are left with 196 square ft. of wall. further dividing 196/200 is 0.98, meaning that Mr. Smith will only need one gallon of paint for his wall.
[(12*18)-(7*3)]/200
(215-21)/200
196/200
0.98
20/100 times 12 = 2.40
then, 12 minus 2.40 = <em><u>9.60
~~~~~~~~~~~~~~~or~~~~~~~~~~~~~
</u></em><em><u /></em><u />80/100 times 12 = <em><u>9.60</u></em><em><u /></em><u />
Answer:
No.
The first term can be represented as
, whereas the second term can be represented as
. In the first term, we are only multiplying 9 by m, and in the second term we are multiplying 9 by m, and by n.
