Step-by-step explanation:
so what you need to do is answer the questions with () and then do the other part
A) 90-55=35 since a right angle is 90 total\
b)ii
Answer: I found the answer of A=9h
X(x - 2) = 4 [upon multiplying and moving the 4 becomes x² - 2x - 4 = 0] x(2x + 3) = 12 [upon multiplying and moving the 12 becomes 2x² - 3x - 12 = 0] 3x(x + 8) = -2 [upon multiplying and moving the -2 becomes 3x² + 24x + 2 = 0]
2nd subtraction property.
