Answer:
x is greater than 0
Step-by-step explanation:
solving the inequality gives x value of greater than 0.
so on the number line from 0 to infinity
Foil it out:
(7x)(4x)+(7x)(9)+(-8)(4x)+(-8)(9)
28x^2+63x-32x-72
28x^2+31x-72
Sum of angles in a triangle is 180 degrees.
2x + 2x + 8x = 180
12x = 180
x = 180/12 = 15
Therefore, the smallest angle mmeasures 2(15) = 30 degrees.
Answer: x=6
Step-by-step explanation:
Do 4x+19x and that is 23x
And then do 12x+5x and that is 17x
Now the equation is 23x=36+17x
Now do 23x-17x and you get 6x
Now the equation is 6x=36
And then divide x by 6 and 36 by 6 and you get x=6
