Answer:
D) 30
Step-by-step explanation:
3(a + 4b)-6 = 3 ( 4 + 4*2) - 6
= 3( 4+8 ) - 6
= 3*12 - 6
= 36 - 6 =30
Answer:
You could use the polygon area formula OR here's an easier solution
We draw the lines DC and DE
Angle ADC = 120°
Triangle ADC is a 30 60 90 triangle
In such a triangle Line AE = hypotenuse * sq root (3) /2
Line AE = 3 * 0.8660254038 = 2.5980762114
Line DE = 1.5
Area of Triangle ADE = .5 * 1.5 * 2.5980762114 =
1.9485571586 square meters and entire area of Triangle
ABC = 6 * 1.9485571586
which equals 11.6913429513 square meters
Step-by-step explanation:
Each person should ride the bike for 4 miles, so that every one has to walk 8 miles and ride 4 miles.
If they had 2 bikes, each person will ride for 8 miles, 4 miles on each bike, and then walk 4 miles.
The answer is A because 24 3/8 inches is roughly 2 feet, 100/2 is 50, and since there is a small 3/8 value, the answer is 49
The answer is -31 2/5<span />
