Answer:
9) 3rd side = 2x+2y
10) 5a^2 + 6a - 3
Step-by-step explanation:
9) 10x+5y - ( 3x+ 4y) = 7x + y
7x + y - ( 5x - y ) = 2x + 2y
10)
I think it’s m(x)=-(x+7)^4-10
Angle b is 65
In order for a shape to be a triangle, all sides have to add up to 180 degrees. Since 65 + 50 = 115 and 180 - 115 = 65,
65 is the answer for angle b

Hey there!
Given equation :
... 0.2 ( x + 50 ) - 6 = 0.4 ( 3x + 20 )
Using the distributive property.
... 0.2x + 10 - 6 = 1.2x + 8
... 0.2x + 4 = 1.2x + 8
Subtract 4 on both sides.
... 0.2x = 1.2x + 4
Subtract 1.2x on both sides.
... - x = 4
... x = -4
Hence, the answer is -4.
Hope it helps!!
