(5x+15)(6x-10)
= 30x^2 + 30x - 50x - 150
= 30x^2 - 20x - 150
Answer:
0,4
1,6
2,8
3,10
Step-by-step explanation:
if x=0, 2*0+4=0+4=4
if x=1, 2*1+4=2+4=6
if x=2, 2*2+4=4+4=8
if x=3, 2*3+4=6+4=10
Answer:
x = 7
Step-by-step explanation:
Set the equations equal to each other, since the two angles are congruent.
x + 16 = 4x - 5 now solve
21 = 3x
x = 7
