Both sides would be the same, so set them to equal ans solve for x.
3x+4 = 2x +7
Subtract 4 from each side:
3x = 2x +3
Subtract 2x from each side:
x = 3
The answer is X = 3.
This is my answer/how I did it :
y+5x=17 can also be 5x+y=17
5x+y=17
-y -y
5x=17-y
+17 +17
5x+17=y (answer)
38. 8•4 =32cm^2
39. 8+8+5+5=26 cm^2
40. Pi•r*2 so = 28.27in^3
41. 15/2=7.5 so pi•7.5^2 so area is 176.71m^3
Answer:
D = 0; one real root
Step-by-step explanation:
Discriminant Formula:

First, arrange the expression or equation in ax^2+bx+c = 0.

Add both sides by 9.

Compare the coefficients so we can substitute in the formula.

Substitute a = 1, b = 6 and c = 9 in the formula.

Since D = 0, the type of solution is one real root.
