the real solutions for the equation 
are -
Step-by-step explanation:
= 
= 0
We can write 64 as 
+ = 0
using the identity ( 
)
we get,
= 
= 
....................(1)
solving the quadratic equation ,
=0
solutions of this quadratic equation can be obtained by
let use y for factors
<u />
..................(2)
from the equation 1 we have,
which gives solution 
and from equation 2 we got
so the real solutions for the equation are -
no. of boys : no.of girls
100 : 140
to get the simplest ratio you gotta divide both with a common factor
Because both 100 and 140 share a common factor of 20
the simplest ratio will be
100/20 : 140/20
5:7
5:7 is the simplest ratio
Golden Gate Bridge, Mountains, Roller Coaster
Answer:
no
Step-by-step explanation:
Hello!
The angles are supplementary meaning they add to 180°
a + 2a + 3 = 180
Combine like terms
3a + 3 = 180
Subtract 3 from both sides
3a = 177
Divide both sides by 3
a = 59
the answer is 59°
Hope this helps!
