I suppose we have to find the lengh of the sides.
Area = lenght × width
288 = (3x) × (2x+10)
288 = 3x (2x+10)
288 = 6x + 30x
288 = 36x
288/36 = x
8 = x
therefore the sides are
3x = 3×8 = 24 inches
2x+10 = 2×8 + 10 = 16 +10 = 26 inches
Answer:
8 is the required answer.
Step-by-step explanation:
In a polynomial, the leading term is the term with the highest power of x.
is the leading term. So, coefficient is 8.

Answer:
- area: 240 ft^2
- bases: 20 ft, 10 ft
- height: 16 ft
Step-by-step explanation:
Apparently, 4/5 of a gallon is used, so covers ...
(4/5)(300 ft^2) = 240 ft^2
The area of the trapezoid is 240 square feet.
__
The short base of the trapezoid is half the length of the longer base, so is ...
(1/2)(20 ft) = 10 ft
The lengths of the bases are 20 ft and 10 ft.
__
The area formula for the trapezoid is ...
A = (1/2)(b1 +b2)h
Filling in the numbers we know, we can find h.
240 = (1/2)(20 +10)h
240 = 15h . . . . . simplify
16 = h . . . . . . . . . divide by 15
The height of the trapezoid is 16 feet.
Answer:
10.5
Step-by-step explanation:
200 miles over 5 inches = 50 miles over x inches
200/5 = 50/x = 200x/250 =
x = 250/200 = 1.25
1.25 inches = 50 miles
