Answer:
108 - 30x - 116x² - 18x³
Step-by-step explanation:
We have to get the value of - (2x + 12) (9x² + 4x - 9)
Now, using the distributive property of multiplication we get
- (2x + 12) (9x² + 4x - 9)
= -[2x (9x² + 4x - 9) + 12 (9x² + 4x - 9)]
= -[(18x³ + 8x² - 18x) + (108x² + 48x - 108)]
= -[18x³ + 116x² + 30x - 108]
= 108 - 30x - 116x² - 18x³ (Answer)
Answer:
(-6, 8)
Step-by-step explanation:
2x + 3(8)= 12
2x + 24 = 12
-24 -24 (subtract 24 from both sides)
2x = -12
x= -6
Answer:
D, -79, plz brainliestt
Step-by-step explanation:
-8(2) -3 = -16-3= -19
-19(4) -3 = -76-3 = -79
Add 2 to both sdies
now if we can facor, then if
xy=0 then x and/or y=0
note:xy=x times y and x(y) =x times y
x^2+3x+2=0
what 2 number multiply to get 2 and add to get 3
the numbers are 2 and 1
(x+2)(x+1)=0
set them to zero
x+2=0
subtract 2
x=-2
x+1=0
subtract 1
x=-1
x could be -1 or -2
x=-2, or -1
All together he made 23.40
One third of $17.55 is $5.85
When you add $17.55 and $5.85 together you get $23.40
