Answer:

Step-by-step explanation:
V = length × width × height
SO...
V = 1ft × 1ft × 2ft
V = 
Answer:
6 units
Step-by-step explanation:
This is an isosceles triangle. Thus, the side marked 'x' has the same length as the other leg (the horizontal leg): 6 units.
Answer:
b. 4 (7 + 6)
Step-by-step explanation:
Finding the GCF between 28 and 24:
We keep dividing while both numbers can be divided by the same factor. So
28 - 24|2
14 - 12|2
7 - 6
There is no number for which 7 and 6 are both divisible by, so the GCF between 28 and 24 is 4.
Simplifying in function of the GCF:
Now, we put 4 in evidence, and divide the rest of the expression by 4. So

The answer is given by option b.
The angles that make a square are 4 right angles. So 360°.
<BAC is half of the square but it's not 180°.
It's 90 because you are measuring BAC not CBA or vice versa.
Conclusion, <BAC = 90°.
