Answer:
(2x + 7)(x + 3)
Step-by-step explanation:
2x² + 13x + 21
2x² + 6x + 7x + 21
2x(x + 3) +7(x + 3)
(2x + 7)(x + 3)
Answer:
-21/2 <-5/2 < - 2 < - 1.75 <-1 <1.75 <9/4
Subtract 2m from both sides : 4m + 3 = -2
Subtract 3 from both sides : 4m = -1
Divide by 4 on both sides : m = -1/4
Answer:
Each daylilies cost $7
Step-by-step explanation:
Step one:
let roses be x
and daylilies be y
so
8x+15y=193--------------1
also
3x+12y=117--------------2
we can solve equations 1 and 2 by substitution
8x=193-15y
x=(193-15y)/8
put x= (193-15y)/8 in 3x+12y=117
3((193-15y)/8)+12y=117
(579-45y)/8+12y=117
579-45y=8(117-12y)
579-45y=936-96y
collect like terms
579-936=-96y+45y
-357=-51y
divide both sides by -51
y=-357/-51
y=7
Hence each daylilies cost $7
put y=7 in eqn 1
8x+15(7)=193
8x+105=193
8x=193-105
8x=88
x=88/8
x=11
rose cost $8
