Answer:
2.6
Step-by-step explanation:
Make this an equation. 5x-4=9. Add 4 to both sides. 5x=13. Divide both sides by 5. x=2.6. So the number is 2.6.

Answer:
x(2x + 3) + (x - 3) (x - 4) = 3x²- 4x + 12
Step-by-step explanation:
<em>Expand:</em>
x(2x + 3): 2x² + 3x
2x² + 3x + (x - 3) (x - 4)
<em>Expand</em>:
(x - 3) (x - 4): x²- 7x + 12
2x² + 3x + x²- 7x + 12
<em>Simplify:</em>
2x² + 3x + x² - 7x + 12: 3x² - 4x + 12
= 3x² - 4x +12
Sum of interior hexagon = 720
m<D = 720 - (100+115+105+130+95)
m<D = 720 -545
m<D = 175
answer
D. 175
Y=mx+b
m=slope
b=y intercept
just solve for y
5x+4y=16
minus 5x both sides
4y=-5x+16
divide both sides by 5
y=(-5/4)x+4
slope=-5/4
y intercept is y=4
