Answer:
4. -2s^9
7. 8b^10
Step-by-step explanation:
First, focus on the number part of the expression. For 4), multiply -2 x -1 x -1 = -2. Then, look at the exponents. When you're multiplying exponents with the same base (in number 4, the base is s), you can add the exponents.
2+3+4 = 9; which makes it s^9. Multiply -2 x s^9, which gives you -2s^9.
Same thing for 7). Multiply all the numbers first. this gives you 8. (Remember two negatives equals a positive). Add all of the exponents of b together, which gives you 10. (when a variable has no exponent, it means that the exponent is 1.) Multiplying 8 and b^10 should give you 8b^10.
It may help to brush up on exponent rules and sign rules.
Answer:
for -11, 28. for 11, -38
Step-by-step explanation:
Typos in your question. can't tell if you need -11 or pos 11
-3(-11)-5 = 33-5= 28
-3(11)-5 = -33-5 = -38
For 1 cookie, cup of flour needed = 5
so, for 144, it would be: 144 * 5 = 720
Then, final answer is 720
Let me know, if you have some doubt
Answer: 7x+14 goes to 7(x+2). 7+7x goes to 7(1+x). 7(x-1) goes to 7x-7). To determine if two algebraic expressions are equivalent by plugging in the same variable value into the expressions. :)
