Answer:
product is 16 • t
Step-by-step explanation:
The first choice
Step-by-step explanation:
7(x - 3) - (x + 3)(x - 3)
(x - 3)(7 - (x + 3))
(x - 3)(7 - x - 3)
(x - 3)(4 - x)
Tan 21 44 = h / 13428.7
h = 13428.7 * tan 21 44
Height = 5353 feet
156/4=39 miles per gallon. 39*12 gallons is 468 miles, and 6 gallons is 234.
Answer:
1. 70.
2. 29.
3. 442.5
4. 289.
5. 632.
Step-by-step explanation:
The key to doing these is to split the polygons into rectangles, triangles or trapezoids as appropriate.
For example, number 1 consists of a rectangle area 8 * 8 and another of 3* 2.
So the area = 64 + 6 = 70 unit^2.
2. The area = sum of 3 rectangles 1*1 + 4*6 + 2*2.
3. Area = 11*15 + 11*15 + 1/2*15*15
4. Area = 18*12 + 1/2 * 6 * 15 + 1/2 * 7 * 8.
5. Area = area of 2 rectangles + area of a trapezoid.
= 18 * 24 + 4*10 + 1/2(12 + 20) * 10.
