Answer:
199 if it's 7b^3 + 10
9271 if it's (7b)^3 + 10
Step-by-step explanation:
You just substitute the 3 in for d. If your expression was 7b^3 + 10, then only b is being raised to 3.
So 3^3 is 27, 27*7 is 189, 189+10 is 199.
If the expression was (7b)^3 + 10, then first you multiply 7 and 3 to get 21. Then you raise 21 to the power of 3, which is 9261. Then you add 10, which is 9271.
Answer: Having your students do speed drills is a way to help them learn quite fast.
Step-by-step explanation:
The lesser x is 2 and the greater x is 3. The x values can be determined by setting each set of numbers in parenthesis equal to 0, so 3x-6=0 and -x+3=0. To solve, take the first set, 3x-6=0 and divide by the greatest common factor, 3, leaving you with x-2=0. Add 2 to each side so that x=2. On the other side, take -x+3=0 and subtract three from each side. Take your new equation -x=-3 and multiply by -1 so that x=3. Therefore x=3 and x=2.
