Simplify: (5s +7s +3)+(78' -5s) A 12s + 2s+3
B 12s + 2s? + 3s
C 12s + 2s* + 3
D 12s + 12s +3

just find the gcf and solve the gcf's until you get each answer i have a really good feeling somethings missing xd (like the dimensions of the fence) *cough *cough *hint *hint

step-by-step explanation:

the answer is 48m^2!

step-by-step explanation:

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2

150.6

all i did was i multiplied 5.02 by 30
