Fist we find the legnth of the diagonal
a^2+b^2=c^2
3^2+4^2=c^2
9+16=c^2
25=c^2
c=5
now the other diagonal
11^2+5^2=c^2
121+25=c^2
146=c^2
sqrt both sides12.083
closest is B
4(2+3x)= 4(2+12) = 4× 14= 56
8+12x =8+12×4=8+48= 56
Yeah, it's equal! Have a great day!
DEF is a isosceles right triangle, so DE =EF. apply Pythagoras:
DF² = DE² + EF² , BUT DE = DF .then DB² = 2DE² = 28²
DE² = 28/2 = 14 and DE = √14 = 3.71 ≈3.7
Answer:
6.08
Step-by-step explanation:
For four brushes its 16 and for two rollers and trays its 16. Add that with the tax and you’ll get 33.92. Subtract 40 with the overall cost to get 6.08
