Answer:
3 coefficients in this expression are: -2x, 5y and 9 (natural number)
Step-by-step explanation:
-6x + 5y + 4x + 9
= -6x + 4x + 5y + 9
= -2x + 5y + 9
3 coefficients in this expression are: -2x, 5y and 9 (natural number)
Hope this help you :3
Answer:
x = 6
<u><em>Sorry if this answer is not correct, if it is or is not, please tell me in the comments!</em></u>
Step-by-step explanation:
All of the angles add up to 180 degrees (since it is a triangle), so
(11x - 3) + (7x + 5) + (13x - 8) = 180
Then, combine the like terms.
31x - 6 = 180
Now, out goal is to separate the x from everything. To do that, we need to add 6 to 180.
31x = 186
Then divide by 31.
x = 6
(Feel free to replace x with 6 back in the previous equation to double check it!)
1 inch =2.5cm
lenght =30.25×2.5=75.625cm
width = 21×2.5=52.5cm
area of painting = 75.625×52.5=3970.3125cm²
I think that would be 9 I am not sure.
