Answer:
49
Step-by-step explanation:
So it seems theres some sort of pattern. When you mutiply 7 by 3 you get 21. When you multply 5 by 7 you get 35. So basically 7 times 7 would be 49. Correct me if im wrong.
X^2-10x+25 = (x-5)^2 or (x-5)(x-5)
[7×(-3)] × (-2)²
= (-21) × 4
= -84
Step-by-step explanation:
ratio of the right handed to left handed is 13 to 2
