Answer:
distribute -5 and -4
Step-by-step explanation:
-5(-6x-9y)-4(-10x+7y)
(30x + 45y) - (- 40x + 28)
30x + 45y + 40x - 28
45y + 70x - 28
Answer:
A triangle equals to 180. Given that it is a right triangle, one angle should be 90.
So, 90+20 = 110
180-110= 70
Therefore, the other two angles are 90 and 70.
The one that makes most sense is the last one, but I would define it as "Two times some number divided by 4".
The square root is 21025 and to 3 sf would be 21000?
