The complete question in the attached figure
we know that
[the <span>square feet of bricks]=9*4+14*3------> 36+42------> 78 ft</span>²
the answer is the option
C) 78 square feet
Is this class economics or something?
Answer:
c=+20
Step-by-step explanation:
6c+14=-50+4+9c
move all terms to the left
6c+14-(-50+4+9c)=0
add all the numbers and variables together
6c-(9c-46)+14=0
We get rid of parentheses
6c-9c+46+14=0
add all the numbers and variables together
-3c+60=0
move all terms containing c to the left, all other terms to the right
-3c=-60
c=-60/-3
c=+20
Hope this helps!!!
