Step-by-step explanation:
16x+4x-20=0
20x-20=0
bring -25 to other side it will become 25
20x=20
x=20/20
x=1
4+6=10 if you have 4 apples and you add 6 apples you are left with 10 apples
Answer:B
Step-by-step explanation:
4x2 =121
4x2-121=0
using the general formula
[-b( +/-) √b2-4ac]/2a
a=4, b= 0, c=-121
x= [0 ( +/-)√02-(4*4*-121)]/2.4
= ( +/-)√1936)/8 = ( +/-)5.5
x =5.5
x = -5.5
The answer is answer choice 3
