Answer:
-18.5
Step-by-step explanation:
15x +4
Let x = -1.5
15(-1.5) +4
-22.5 +4
-18.5
10(N + 3)
= 10N + 30
Hence, the answer is A.
Answer:
I will list main feature for each property and you can choose. You can comment if you want to check or have questions
Step-by-step explanation:
Isosceles - two sides are equal
Equilateral - all sides are equal
Obtuse - one angle is greater than 90 degrees
Right - one angle is equal to 90 degrees
Scalene - none of the sides is equal
Acute - all angles are less than 90 degrees
Go down the list and see if it's true or false about the given triangle
3x+y=17
=> 3x=17-y
Again, x+3y=-1
=> 3y= -1-x
now, 3x+3y= (17-y)+(-1-x)
= 17-y-1-x
= 16-x-y
Answer:
B
Step-by-step explanation:
A cylinder is like circles staked on top of each other so you want to find the are of the top circle which is 28.26 because pi r^2 (3^2)*3.14. now you found the area of the top circle. The height is 10.5 so that means there are 10.5 layers so you multiply 28.26 by 10.5 i know its confusing im new to brainly but hopefully this answer helped you You will get 296.73 because i rounded pi to 3.14 but the answer is B
