58/2=29
29 is prime
prime factorization is 2 times 29
I'm pretty sure it's C. It seemed confusing at first to me, too. Good luck on your test!
YOU CAN WRITE AN EQUATION OF 7.5 Divide 2.5 = any letter
Using how tall it is over how wide
=>tall/wide
The model 15in/1.5in
The actual x/55ft
Convert everything into the same units so 55ft to inches
There are 12in in 1ft
55ft * 12in/1ft
The ft cross out leaving in
55*12in= 660 in
So
15in/1.5in = x/660in
Now solve for x my multiplying both side by 660in
660in *15in/1.5in=x
x= 6600in tall
