Answer: 2/3 + 1/4 = 11/12
The least common denominator of both denominators is 12.
The first fraction , 3 x 4 = 12
2 2x4 8
— = —— = —
3 3x4 12
The second is the same , 4 x 3 = 12
1 1x3 3
— = —— = —
4 4x3 12
Add both fractions:
8 3 8 + 3 11
— + — = ——— = —
12 12 12 12
Width = w
Length = 3w - 6
Area = 360
Equation Area = wl
w (3w-6) = 360
3w^2- 6w = 360
3w^2 - 6w - 360 = 0
3 (w^2 - 2w - 120)=0
3(w + 10)(w - 12) = 0
w = -10 & 12
l = 3w-6 = 3 (-10)-6= -30 - 6= -36
l = 3w-6 = 3(12) - 6 = 36-6 = 30
Answer: -10 and 12. Yet, since this is a measurement, it must be positive so 12 ft
No
0.04 is actually smaller than 0.4 because the four is in the hundredths place which is smaller than the four in the tenths place of 0.4
Answer:
Convex, since none of the angles are greater than 180°
3 over 2 and 3 over 4 (1.5 and .75)
