Answer:24+4x
Step-by-step explanation:
a=5. PHOTO
b=7. PHOTO
a1=5+x. FRAME
b1=7+x. FRAME
Pf=2*(a1+b1)
Pf=2*(5+x+7+x)
Pf=2*(12+2x)
---------Pf=24+4x. - - - - - - PERIMETER OF FRAME
5/6+3 3/4
Well first you make 3 3/4 a mixed fraction so that would be 15/4 then find the GCF of 4 and 6 and that would be 12 so multiply everything by 12
12(5/6 + 15/4) = 60/6 + 180/4 now make the fraction into whole numbers
60/6= 10
180/4=45
Now all u simply have to do is add them together 10+45=55
HOPE THIS HELPS!!! :)))
When dividng fractions, we do keep change flip. So, it would become:
3/5 * 7/6 = 21/30
21/30 = 7/10
Simplest form = 7/10
