Answer:
6.3 km.
Step-by-step explanation:
The question asks for kilometers, so all amounts have to be calculated in the same units -- kilometers.
Convert meters to kilometers.
600 m = .6 km
700 m = .7 km.
Add the amounts:
Fri.: .6 km
Sat. 3 km
Sun.: 2.7 km.
--------------------------------
6.3 km.
Answer:
B. 50
Step-by-step explanation:
5^2 +7*3 +4 = 25+21+4
= 25+25
= 50
Area of triangle=1/2(base×height)
360=1/2((4x-2)(7x+5))
720=(4x-2)(7x+5)
FOIL the binomial
720=28x^2+6x-10
Bring 720 to the other side
28x^2+6x-10-720=0
28x^2+6x-730=0
Factor 2 out
2(14x^2+3x-365)=0
Factor 2(14x+73)(x-5)=0
x-5=0
x=5
It can't be 14x-73=0 because the length can't be negative.
You're welcome.
