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)
Answer: 9
Step-by-step explanation: the base is 6 and the height is 3. The formula for a triangle is A = 1/2bh
6 times 1/2 is 3
3 times 3 = 9
0.0000009
.9 times 10 is 9, so then you have to move it back -6 times behind the decimal.
