Answer:
2x^2+4x-30=0
Step-by-step explanation:
2x^2+10x-6x-30=0
2x(x+5)-6(x+5)=0
(2x-6)(x+5)=0
2x-6=0 x+5=0
x=6/2 x=-5
x=3
Yes! it is not going to be like a right triangle or idk how you call the equal triangles but you can still make a triangle
Hello
(n-2)*180 where n is the number if angles in a polygon
(38-2)*180
=36*180=6480
(29-2)*180=4860
1 angle -> 4860/29 = 167.58
You do the same here
(1026-2)*180=184,320
184,320/1026=179.64
They're complementary so 180-179.64=0.36°
(36-2)*180=6120
6120/36=174.85
180-175.85=5.15°
Answer:
-1, 0, 1
Step-by-step explanation:
the blue and red lines overlap to give a solid dot above -1 through to 2, which has an open dot above
therefore, -1 ,0, 1 are the only integers that would be in the solution set
i believe u r confused about the 5 tanks because 18 can not fit into 5. so here is what it would accurately be.
to find out how many tanks you need your going to need to find the least common multiple. the least common multiple for both are below
18: 1, 2, 3, 6, 9, 18
24:1, 2, 3, 4, 6, 8, 12, 24
the least common multiple is 3. you will need three tanks. now for part b of this equation, to find out how many of each need to be put into the tank. to find this out you need to divide 18 plant and 24 fish by 3 tanks.
18/3 = 6
24/3 = 8
6 plants will go in each tank and 8 fish will go in each tank
the ratio is 6:8 per tank
