Answer:
(x-1)(x+5)=0
x=1; x=-5
Step-by-step explanation:
x²+4x=5
x²+4x+2²=5+2²
(x+2)²=3²
(x+2)²-3²=0
(x+2-3)(x+2+3)=0
(x-1)(x+5)=0
(x-1)=0 ; x=1
(x+5)=0; x= - 5
Positive add a positive plus positive equals positive neg plus neg equals neg
Answer:
15%
Step-by-step explanation:
not that hard just make it a decimal then at the point go back twice and there its 15%
<span>x-y=192 or x=192+y
y=x/5 now replace y with (x/5) in the first equation & solve for x
x=192+x/5
x-x/5=192
4x/5=192 cross multily
4x=5*192
4x=960</span>
Answer:
A quadratic function has the formula y equals a x squared right and once you have a square.
