Answer:
32.5 square feet.
Step-by-step explanation:
The formula for a triangle is Base times height divided by 2. So, you must divided this shape into a square and a triangle. Now, we must find the base of the triangle, which is 3 and find the height of the triangle, which is 5. Multiply 5 by 3 to get 15. Divided by 2 by 15 to get 7.5. Then find the area of the square. Simply find the base of the square, which of 5 and find the height of square, which is also 5. Multiply 5 by 5 to get 25. Add, 25 to 7.5 to get 32.5.
If i did it right that should equal to -2
The width and length of this rectangle are 3 7/12cm and 4 1/12cm respectively.

Answer:
a) 1.28
b) 2.57*10^-7 mg²
c) 8.14*10^7 dm
d) 3.79 m/s
e) 9.78*10^-3 mg
Step-by-step explanation:
a) 7.31 / 5.7 = 1.28, km/km is the same unit, so they cancel each other out. The answer is 1.28 without unit.
b) (3.26*10^-3) * (7.88*10^-5) = 2.57*10^-7 mg², here, mg * mg, this is mg²
c) (4.02*10^6) + (7.74*10^7) = 8.14*10^7 dm, here, the unit are added together, so we maintain it
d) (7.8 - 0.34) m / (1.15 + 0.82) m = 7.46 m / 1.97 m = 3.79 m/s, here, the numerator has the unit of m, and the denominator has the unit of s. Giving us m/s.
e) (9.88*10^-3) - (9.66*10^-5) = 9.78*10^-3 mg. Here, the unit was subtracted from each other, so we maintain it.
