Answer: (-5x2 - 8x + 7) - (5x2 - 4)
Step-by-step explanation:
= -5x2 - 8x + 7 - 5x2 + 4
= -5x2 - 5x2 - 8x + 7 + 4
= -10x2 – 8x + 11
Answer: = (-5x2 - 8x + 7) - (5x2 - 4)

Step-by-step explanation:
(18)
Since BD is an angle bisector , then
∠ DBC = ∠ ABD = 57°
∠ ABC = ∠ ABD + ∠ DBC = 57° + 57° = 114°
(19)
Since BD is an angle bisector , then ∠ ABD = ∠DBC
∠ ABC = 110° , so
∠ ABD = ∠ DBC = 110° ÷ 2 = 55°
Step-by-step explanation:
B) the sum of 3 times a number and 4

The answer for this would be 23.4.
This is because 1.3 = 1 mile. Therefore you should do 1.3 x 18
which equals 23.4!
