Answer:
1. If x = 4 and y = 8, u = 3x - 4 would make sense because 3x, or 3 x 4 = 12
12 - 4 = 8 y = 8 (True)
2. m = 12 and n = 200 . n = 15m - 20 15 x 12 = 180 180 - 20 = 200 Would not make sense because 180 - 20 is 160 (False)
3. a = 5 and b = 48 b = 48 . 8a + 8 = 8 x 5 + 8 8 x 5 + 8= 48
(True)
4. G = 40 and h = 1000
H = 25g + 300
25g = 1000
1000+300= 1300, not 1000
(false)
Answer:
B. 271 square units
Step-by-step explanation:
The area is the sum of 3 rectangles areas
step 1 12 * 19 = 228
step 2 3 * 3 = 9
step 3 2 * 17 = 34
Now, we add all the answers we got to get the area.
= 228 + 34 + 9 = 271 square units
