Yes you will regroup because 8+3 equals 11 so you would bring the 1 down and add the other to the 4 and 2
let the unknown side be x , so we have :
25^2 = 20^2 + x^2
625 = 400 + x^2
x^2 = 625 - 400
x^2 = 225
x = √225
x = 15
Answer:
The graph that matches is D.
Answer:
x² + 3x - 10
Step-by-step explanation:
(x-2)(5+x)
5x + x² -10 -2x
simplifying:
x² + 3x - 10
334 is the answer to the question
