Answer:
B
Step-by-step explanation:
I dont get the first statemet, that 2 angles are 90 degrees, because that isnpt possible for a triangle, but a triangle must add up to 180 degrees, and if you have one that is 90 degrees, then you are half way there, then you get 50 more degrees, and you have 40 left, so B is the answer angle C is 40 degrees,
PLS MARK BRAINLIEST IF YOU CAN :)
Its c hope that helps text me back if you want to know why it is.
Answer:
5x²(2y + 5)
Step-by-step explanation:
10x²y + 25x²
to start we have to express the parts of the function as multiplication
2*5*x²*y + 5*5*x²
then we have to see that they have both parts of the sum in common, and what they have in common we get out of common invoice and what is left we add together.
5x²(2y + 5)
9/20
explanation:
7/10 - 1/4
14/20 - 5/20
14-5/20
9/20
Answer:
1. -7.5
2. $1
3. 40
Step-by-step explanation:
For number 1, it can be solved by using the PEMDAS method, or see explanation below:
6x - 4x - 36 = 6 - 2x
2x - 36= -2x + 6
4x + 36 = 6
4x = -30
x = -15/2 or -7.5
For number 2, substitute 3 into both equations:
f(x) =1.50(3) + 2.00
and
f(x) = 2.00(3) + 1.50
This would get $6.50 and $7.50, which, if subtracted, gets $1.
For number 3, do something similar to the previous problem. Substitute 3 for x. It would be 5(2^3), or 40.
Hope this helps!
