cross multiply the equation to give you
1= a(2bh+3)
divide both sides by a(2b+3)
answer is 1/2ab+3 = h
20+2•(5+4^1) keep in mind of PEMDAS, so solve in the order P: Parentheses E: Exponents(in this case you would solve the exponent before the parentheses M: Multiplication D: Division A: Addition S: Subtraction
K (-3,-3)
L (1,-1)
M (-1,-5)
N (-5,-7)
Answer:
este bien.
Step-by-step explanation:
First step: x= ± √ 121
