Answer:
Step-by-step explanation:
7x + 3 = 9x - 19
-2x + 3 = -19
-2x = -22
x = 11
DE= 7(11) + 3 = 77 + 3 = 80
EF = 9(11) - 19 = 99 - 19 = 80
80 + 80 = 160 for DF
Answer:
-2<x<1
Step-by-step explanation:
-5 < 8x + 11 < 19
Subtract 11 from all sides
-5-11 < 8x + 11-11 < 19-11
-16 < 8x<8
Divide by 8
-16/8 < 8x/8 <8/8
-2<x<1
Hello,
To solve, factour out the expression: <span>9a^4b^4-27a^3b^3+18a^3b^2.
Once factoured out you get the GCF 9a^(3)b^(2)
