(x+y) is the coefficient of xy
Answer:
12 square feet
Step-by-step explanation:
You can find out how many square feet he bought by dividing 432 by 3.
432/3=144
Now, you need to find the square root of that to find the length of just one side of the room.
Answer:
a=1 because 3x means 3 multiply 2 and it is substracted from 7 and 7-6 is 1
b=3
c=9
Step-by-step explanation:
hope you will understand from the explanation of a
tan 52 = 180/a; a = 180/tan 52
tan 43 = 180/b; b = 180/tan 43
you need to calculate, a-b = 180/tan 52 - 180/tan 43
substitute the value of tan thetas, and calculate it simply...
Answer:
1 hour
Step-by-step explanation:
25min=1 poster for the shop owner
25×4=100
100×8=800
800÷25=32 posters in 8hrs for the shop owner
1hr×8=8 posters for the apprentice
thus 40 in total
