(-1,-4) plug it into the calculator on the graph and you’ll find your answer
A = 1/2[(7)(19) + (12)(19)]
A = 1/2[133 + 228]
A = 361/2
A = 180.5
answer
D. 180.5 square inches
(ab+3)(ab−3)
=(ab+3)(ab+−3)
=(ab)(ab)+(ab)(−3)+(3)(ab)+(3)(−3)
=a^2b^2−3ab+3ab−9
=a^2b^2−9
Answer:
4
Step-by-step explanation:
Because when you multiply the 9 by x you get 9x and when you multiply the 9 by 3 you get 27. So then your final answer would be 9x + 27.
I hope this helps!! :)
