Answer:
240 ft^2
Step-by-step explanation:
If you know you have 6 triangles then you can just find the area of one and then multiply by 6. First find your formula: (b)(h)/ 2
Next plug in: (8)(10)/2 = 40
Now you know the area of one so multiply by 6: (40)(6) = 240 ft^2
2/6. because there are 6 part of the square and there are 2 that are shaped red.
Answer:
Step-by-step explanation:
This is exponential growth which has the form
1 + 2^1 = 3
3 + 2^2 = 7
7 + 2^3 = 15
15 + 2^4 = 31
31 + 2^5 = 63
63 + 2^6 = 127
so the next two terms in the sequence 1, 3, 7, 15, 31, is 63 and 127.
For this case we have the following expressions:
-4x-8
-2 (x + 1) -2 (x + 3)
Evaluating x = 3 in both expressions we have:
-4 (3) -8 = -12 - 8 = -20
-2 (x + 1) -2 (x + 3) = -2 (3 + 1) -2 (3 + 3) = -2 (4) -2 (6) = -8-12 = -20
Answer:
the value of each expression when x = 3 is:
-20 and -20
