3x^2 + 4x - 21x - 28
x(3x + 4) - 7(3x + 4)
(3x + 4) (x - 7)
Answer: B).
Answer:
x<7
Step-by-step explanation:
4(5−2x)−3x>8x−113
−11x+20>8x−113
−11x+20−8x>8x−113−8x
−19x+20>−113
-20 -20
-19x>-113
/-19 /-19
(flip the sign)
x<7
i can't do the greater than or equal to sign so just remember to add that in :)
Answer:
D
Step-by-step explanation:
-2x+8.1y
+9x-5.3y
________
get the answer 7x+2.8y
<span>B. (x + 1)2 + (y - 7)2 = 16
</span>D. (x + 2)2 + (y - 5)2 = 9
Step-by-step explanation:
5x+8-x=3x+6
5x-x-3x=-8+6
4x-3x= -2
1x= -2
Therefore,LHS is not equal to RHS
