(x + 5) / (3x + 4) + (x + 4) / (x + 3)
[(x + 5)(x + 3) + (x + 4)(3x + 4)] / (3x + 4)(x + 3)
(x² + 8x + 15 + 3x² + 16x + 16) / (3x² + 13x + 12)
(4x² + 24x + 31) / (3x² + 13² + 12)
The first option is correct.
Answer:
B
Step-by-step explanation:
X subtracted from y means y-x
h+3 subtracted from 6h+1 means 6h+1-(h+3)
din't forgtet to distribute invible -1
6h+1-1(h+3)=
6h+1-h-3=
6h-1h+1-3=
5h-2
Answer:
x = 29
y = 110°
Step-by-step explanation:
y° = (3x + 23)° => corresponding angles are congruent)
(2x + 12)° + y° = 180° => linear pair
Thus:
(2x + 12)° + (3x + 23)° = 180° => substitution
2x + 12 + 3x + 23 = 180
Add like terms
5x + 35 = 180
5x = 180 - 35
5x = 145
x = 145/5
x = 29
✔️y = (3x + 23)°
Plug in the value of x
y = 3(29) + 23
y = 110°
